Variable Valve Timing.
The Toyota version (essentially same as the Alfa Romeo one)
uses oil pressure to rotate the intake camshaft relative to
its pulley. This is activated by means of an electrically controlled
valve of course. It is therefore possible to use very agressive
cams for good top end power: the 4A-GE VVT peaks 165hp@7800rpm!!!,
while still having decent low end torque and idle.
This is not a new technique, Alfa had it in production in mid-80's,
and Toyota was experimenting with it too in prototypes,
at least during the development of 1G-GTE engine but the VVT
was dropped in the production versions.

To me this seems a bit strange as the exhaust change shouldn't increase
maximum boost (that's controlled by the wastegate) it only allows you to
reach maximum boost more quickly. The turbo may be spinning up so quickly
that it is over-boosting before the wastegate can react which is unusual
as wastegate creep (slight opening before max boost) is a problem common
to most turbo systems and incidently a good source of horsepower if you
can fix it. Anyway as i understand it (and i'm only guessing here) this
fuel cut defencer just bypasses the standard computers fuel cut (rev
limiter?) allowing you to get the extra fuel required if you run extra
boost. Sounds good to me although it's bloody expensive for what it does.
I have seen 'do it yourself' boost limiter by-pass systems that cost under
$50 Aust. to make. The only problem I can see with using this system with
the standard injectors is that if you increase the boost to a level where
the standard injectors can't keep up (above the 90% duty cycle is getting
iffy) then you run the real danger of running lean, which at max boost
gives your motor about ten seconds before it shits itself. Just something
to think about anyway.

Just for your information, after removing the catalytics from my RX-7, boost
went from 6psi-10psi with no other change.. the wastegate dump has too small
of an opening to maintain correct boost pressures.. it wasn't really boost
"creep" (atleast not like the Talon/Eclipses).. it stayed consistently 4psi
higher than stock :) and your're right, it was a good source of additional
horsepower.. :)

--------------------------
I have a friend with a Mazda 323GTX (the turbo, AWD, 16V rally special)
which came with an overboost alarm from the factory. He has an HKS
air filter (the cone type) and exhuast system on the car. On cold days
the overboost alarm comes on repeatedly. This can be cured by intalling
an airflow limiter in the intake (which the previous owner did), but then
all gains from the new parts is lost. (BTW, we removed that stupid limiter
and the car ran far better.) Ond bad thing is that the car doesn't have
a boost gauge, so we don't know if the car really is making more than the
allowed 10psi or if some sort of airflow sensor is being fooled by the
increased airflow. But it seems that minimal modifications to turbos will
result in overboosting.

Also, it turns the car into a booming resonator at 3200-3800rpm. Yes, I
know I shouldn't be down that low, but on the highways here in the US,
maintaining the 76mph it takes to get above this zone can play havoc on

had to do some minor revisions to get mine to fit properly, but some of that

Sorry I didn't make it very clear at first time. I meant that Toyota
experimented with VVT already over 10 years ago, but it only got
into production very recently (not sure exactly when, between 93-95).
So far it's only available in Japan. I'd guess it should be
an easy task to replace an older 4A-GE with the VVT/20-valve one.

If they are 550cc, and are compatible with the 7MGTE ECU (as they seem

an HKS FCON and not have to fool with the Lexus airflow meter and 300ZX

BTW Reg, any further update on how the Lexus injectors & airflow

Well, I'm looking to run 15-20 psi on my rebuilt motor, which I
expect will be in the range of 400-500 hp. If I could get 400 hp with my
current injectors, then down the road replace them and get 500 hp,
that'd be great. As it is I'd have a lot of trouble paying the full
$2600 for the HKS FCON & injectors, but if I could get 400 hp without
having to upgrade the injectors that'd probably hold me until I could
afford the injector upgrade.
So what's necessary to get 400 hp worth of fuel from the stock
injectors? Just an FCON? What else?
Thanks a bunch for the help.

Christopher,
Most of the cams for the 4AG-E motor made by TRD
and HKS were pretty much the stock lift i.e ~7.6mm. The most radical
was I believe 302/10mm and this according to the TRD book required
machining the head for the extra clearance. I am running 288/288 cams
with no problems as regards the stock valvetrain, however, these cams
are the limit for the EFI system. Some people I have talked to said
it would not work (including TRD) . TRD recommends their high
performance valvetrain from 288 up along with sidedrafts but the
price of the parts is kind of prohibitive.

As usual the theoretical is trashed by real world experience. It seems
that if the wastegate is a bit on the small side then it can't shed the
excess exhaust gases resulting from improved flow and over boosting
results. I'm not sure if this is a good thing or not. On one hand you get
the benefits of that extra boost but on the other hand that boost is
uncontrolled, a possibly expensive situation. The turbos i have
experience with are either standard or the boost is turned way up (over
standard) so i have never come across a wastegate that couldn't maintain
the specified level of boost. There you go, live and learn. Still can't
decide if this is a good or bad thing to happen, any ideas ?

What volume does the stock MR2 flow? Isn't 750cc a bit of an overkill as
500cc will be good enough for about 500 horses. I guess nothing is overkill

Hi Bruce,
I saw this motor used in a car that was similar to the MR2 in Car

was rear wheel drive. So why would this not be a good drop in for the MK1

Hi Aly,
I think Bruce meant "not a good drop in for a Front-engined RWD". For

HKS recommends you limit boost to 13.5 psi until you upgrade the
injectors. Do you agree with this? I can already get 11.5 psi without
buying the FCON, and $1000 for the FCON seems like a lot of money for
just 2 more psi (about 9% more power).
Anyway, to bring you up to speed on some of the tales about my car
that the older folks have already heard, I originally had Turbonetics
upgrade my CT26 with a Super-S compressor wheel, and that thing had
incredible response. Boost was obtained almost instantly, it would hit
full boost below 3000 rpm (with the EVC). But I noticed the boost would
drop just a bit around 6000 rpm at 11 psi of boost. Anyway, that turbo
blew apart due to a failure in manufacturing on Turbonetics' part. They
rebuilt the turbo for free (didn't pay the mechanic labor costs though).
At that point, I already knew I wanted to run more boost and figured
the Super-S couldn't keep up, so I was going to go the next step up, the
Super-V. For whatever reason they were out of stock on V wheels and I
didn't want to wait, so they urged me to get the next step up, the
Super-H. I was worried about boost response, but they said it would be
fine. So they put in the Super-H and clipped the exhaust wheel.
Anyway, turbo lag is fairly significant with the Super-H. I can't
get full boost below 4000 rpm even with the EVC. But this thing should
be able to flow tremendous amounts of air without excessive heating. But
I can't take advantage of that until I upgrade my fuel system. :(
So I already have been running the Turbonetics CT26-Super-H upgrade,
and my other mods are HKS EVC III, HKS 75mm exhaust, Cartech Intercooler,
no EGR, no cat. I was using a K&N replacement filter (not FIPK), but
with the recurring controversy about filtering ability I just put in a
stock Toyota filter last time the engine was rebuilt. :(
BTW, anyone have a source for replacment 7MGTE downpipes without the
downpipe-cat? For off-road uses only of course.

I doubt a normally aspirated Lexus V8 would use 8 550cc injectors.. but, the
so-called HKS 550cc injectors are just Mazda RX-7 Turbo II injectors (I
think the 87-88 only).. I'm sure you'd be able to pick them up at a Mazda
dealer for much less.. the 84-85 RX-7 GSL-SE used 2 680cc injectors if you
can find those..

FWIW, I've found an excellent source for fuel injectors. A company named
Python makes reconditioned injectors for almost any type of car, and
they cost less than half as much as from other suppliers. For example,
Beck-Arnley (probably the largest distributor of OEM repair parts for
imports) sells 3SG injectors for around $85 each. The Python injectors
would be about $40-$45 each. If anyone is interested in finding out
the availability of injectors for a particular application, I only
need to know what the stock application was (year/make/model.)
As for the comment that the HKS injectors are the same as those found
stock on the 87-92 RX-7 T, that could be true, but I think the years may
be off a little bit. I've got a Python part number 627-091 listed for
the 86-88, then a 627-093 listed for the 89-92. I'll check price on
these and post it later today.

To the list,
The VVT motor, which is 5 valve has been available since 1991 in Japan, there
are a few examples in Australia which have been imported. The engine looks
very different to a normal 4AG, the EFI looking like an electronic Webber.
The compression is 10.5 and all other details can be found on the Toyota CDROM
EPC for the AE102. Also for those who are actually measuring the duration of
their CAMS, like Bill S, it might shock you to know that an HKS 264 will
measure around 280 when cold. The VVT (5 valve) is not a good drop in for RWD
as the distributor is at the back, I think its better to fit the VVT cam to the
4 valve 4AG.

To the list,
The VVT was found in a front and 4WD Corolla. It was also available in a
126KW Supercharger version I seem to remember. The car that some of you have
written to me about is probably the MRJ or its prototypes. This is NOT the
1600 VVT but an 1850 I think. The VVT will fit in the early MR2, this is
technically a RWD but we tend to think of it as a FWD as its the same assembly.
For 'real' FWD's like the AE86 the VVT and for that matter the 3SG distributor
will hit the fire wall. To fix this you need to run crank fire ignition such
as Electromotive and have a laptop. I have helped install a 3SG in this manner.
The crank fire system is worth as much as the VVT 4AG.

Hi Chris, good timing on that injector source. I need some replacement

but unfortunately these injectors have a weird design and won't fit my

fit, so firstly do you (or anyone else) know if this injector is an o-ring

Subject: Panasport Wheels Order/Group Buy
(snip snip)
Panasport is a premier maker of road wheels for racing and street purposes.
I bought
4 for the race car about a year ago. Those who get SportsCar can take a look
through
the ad section in the back and see a picture if you don't know what they
look like.
If you've got web access, http://www.emi.com/~bownes/spit.html has some pictures
of my race car with them on it.
Panasport offers two types of wheels, street and Lights. Lights are for racing.
The race wheels are marked as such and are NOT DOT approved for street use. Most
of what we bought last time were Lights.
Last time I gathered orders over the net and went through a local guy who
offered
to sell them with little markup. The Lights prices ended up looking like this
(more or less,as I recall)
13" $130 + S&H
14" $145 + S&H
15" $155 + S&H
There were a couple of oddball wheels we ordered that were not in this
range, so
it's not +/- 3 sigma or anything, but it's close. (The 17"x13" stick in my
mind...)
This time I'm going to try something a little bit different. If we can get
enough
wheels ordered, I will get them directly through Panasport and set 0.030"
Over up as
a distributor. But I expect that that's going to be something on the order of
20-30 wheels, which is about the volume we has last time. So, we are faced with
a chicken and egg problem. I won't know the pricing until I get a wheel
count, and
most of you are bright enough to not commit to something without knowing
what it's
gonna cost. If we don't get enough, I'll go back to my local guy and see if
we can
get the deal again with whatever count we have. But my gut feel is that
we'll have
enough.

Here is the scoop on the Python injectors. Most common part numbers

While this is not possible if you are putting an RX-7 injector into

these. (At least I don't _think_ they'll take a 7M injector in place
of an RX-7. On second thought, I'll bet that they don't even look at
them...)
Here are some part numbers:
3SG Turbo injector: 640-167

7MG injector: 640-181
7MGTE injector: 640-164

Get the poly ones. You will need to lubricate them once a year (install

Along the same lines as what Bill posted, I am attaching the "cut-n-paste"

Since then, I am willing to make concessions only for ECU's that are
able to increase the boost on a turbo-charged engine. In other words,
these at least have a _hope_ of working. Pouring more gas and timing
into the car with total disregard for what level of performance upgrades
have been added to the car has negligible benefit at best.

-------------Begin CAP's cut-n-paste answer to ECU upgrade req's---------
Here at CAP, we're asked literally every day if we carry a line of
prom/ECU upgrades for various cars. It makes sense if you consider
our market: Folks familiar with computers, who typically have newer
"computer controlled" cars that are less performance upgrade
friendly. As a matter of fact, our Web site still reflects a
section that we planned on devoting to just this topic--and never
did.
After much consideration, we have decided that at this time, we will
not carry a line of prom/ECU upgrades. The bottom line: we're
still not sold on them. There are just too many folks out there
running around selling super-proms that are just of marginal
improvement at best and detrimental to performance at worst. As a
matter of fact, we personally know of one situation where a
prominent upgraded prom manufacturer was caught selling a prom that
was an exact duplicate of the auto's original prom, along with an
upgraded wastegate. (It was a turbo application.) When confronted,
the president of the company admitted what was done, and justified
his actions by stating that everything he sold had a money back
guarantee, and that none of the customers who bought that package
had requested their money back. He sold them a valve (which I've
been told can be purchased for roughly $15 through an aquarium
supply distributor) and the duplicate prom for several hundred
dollars. As a company founded on the priciples of value and
honesty, we have a real problem with that!
Even if the prom upgrade manufacturer is honest (and I'm sure many,
if not most of them are), a "prom upgrade" is a bit like vapor-ware.
The automobile manufacturers spend billions of dollars designing
engines that are powerful, efficient, and operate cleanly. They
don't just leave out power for no reason. If they don't get every
possible horsepower that an engine is capable of producing with
it's stock components, it is because they've traded a small amount
of performance for economy, reliability, or for the sake of the
environment. Fortunately, with the advances in manufacturing tech-
nology, these tradeoffs are minimal. The improvements are usually
insignificant next to other variables such as tuning, driver
ability, and weather.
There is a real need for prom upgrades that will allow a car to take
full advantage of available upgrades. Certainly, the enhancements
offered by performance upgrades commonly sought through aftermarket
dealers (such as K&N Filtercharger Filters, Magnecor competition
spark plug wires, Jacob's ignitions, and DynoMax exhausts, as well
as others) are valuable. However, to be able to take advantage of
other upgrades, such as cams or high compression pistons, one must
reprogram the ECU on today's high-tech engines. There are some
in-car programmers available today, unfortunately they are still
quite expensive, and usually limited to a very small group of auto-
mobiles. They are definitely not for the average driver who just
wants to add little more pep to the daily driver.
We appreciate our customers' interest in performance prom upgrades.
However, it is in these same customers interest that we have chosen
to avoid them for now. We realize that we will lose some sales
because of this, but feel that there is something more important
than sales at stake: our reputation.

Chris, do they list injectors for the 18RGEU ? If so are these
interchangeable with those from a 7mgte. Trying to find an appropriate

turbo. This used but good T3 has 0.63 A/R turbine housing and
45-trim compressor. Yes, I know the compressor is too small
for my needs and I may get a larger one even before I get back
on the road. The T04B S-trim compressor seems to be the best
affordable choice. The T3 50L would also be ok, but is more expensive.
As I had to stop driving during the Xmas holidays due to the
excessive oil burning (coming through the turbocharger oil seals),
I could at this point start as well disassembling the old setup.
Once the plumbing was removed, I could check the clearance of
the turbo bearings. Heheheh... some 4 mm radial on the turbine
side, 2 mm on the compressor side, 3 mm axial = toast.
Getting the turbo out required removal of something from the way,
in this case we picked the exhaust manifold.
After measuring the exhaust ports I got the feeling that at least
they COULD be larger, but is it really needed? I know already
of one porting work on the exhaust side of 3T-GTEU which went
to the oil channels, was welded but didn't hold after that.
These are rectangular in shape, about 32*26mm (approximately
equal to a 32mm round port). This is small compared to the 45mm
exhaust valves... Bill?
The CT20 has approximately equal turbine side to a .48 A/R T3,
and the compressor side size is between 40 and 45 trim T3.
The compressor wheel inducer diameter is 38mm and tip diameter 58mm
The T4 S-trim has a 48mm inducer and 70mm tip diameter.
Next I need an adapter to connect the T3 to the current manifold,
everything else (intake tubing, oil lines, exhaust) is then much easier...
I'll also move the battery to the rear and put the air flow meter
in its place.

Does anyone have any experiences of superchips, turbochips, starchips

Hi James,
Where did you get this number? Is it something you timed or you just
guessing? 2.8 seconds is pretty fast. A BMW M formula engine is at 2.1
seconds.

According to Turbo magazine it is a '73 -> KE20...
But probably no longer with a K-series engine ;)
It ran 12.25@106mph

Those numbers are very realistic for a MA70 with 330 REAL horsepower.
I ran a quick simulation and came up with about 2.7 seconds 60-80mph,
4.8 seconds 0-60, top speed 163mph.
I'm aiming for 2.6-2.7 seconds 60-80mph myself, but with a lot less
top speed - 150-155mph (it's a brick and I run out of revs anyway).

Matti,
If you run your simulation, how many HP is needed to accelerate a car (given
the supra's weight) from 60-80 in 2.1 secs? Just curious. I remember the
formula engine has a rating of about 900 horses.

Hm, that does sound interesting. So you do recommend a supplemental
second fuel pump? What brand and model? How hard is it to install?
Also, what's involved in tweaking the GCC?

I just ran cartest on the stock '89 supra turbo.
60-80 in 3rd gear 4.3 seconds (230HP@5600, 254ftlb@3200rpm, 3770lbs)
60-80 in 3rd gear 3.2 seconds (299HP@5600, 330ftlb@3200rpm, 3770lbs)
supposed to approximate an HKS stage IV supra.
60-80 in 3rd gear 2.0 seconds (453HP@5600, 500ftlb@3200rpm, 3770lbs)
approximate an HKS state VIII supra. (okay, so it's a wild guess)
60-80 in 1st gear 2.2 seconds (625HP@5700, 630ftlb@4900rpm, 3570lbs)
60-80 in 2nd gear 2.0 seconds (625HP@5700, 630ftlb@4900rpm, 3570lbs)
Vector W8 TT (my other dream car, 0-60 3.6s, 11.8@129.2 1/4mi)
these are just guesses at torque figures, and the HKS stuff doesn't
list rpms for anything. But stage III and IV are rather common so I
took the 299/330 from a fax I got from a friend who had his dyno'd
2 years ago with a makeshift wastegate valve bleedoff a pacesetter
exhaust and a K&N FIPK. Um. that's stage III, he was running just
under the fuel cut. (he also had some internals strengthened, but I
don't think that should throw things off that much)
I can't imagine driving something with 390 ftlbs of torque.

all the figures quoted were from their literature
i'm gonna send Reg Riemer photocopies of these and see what he
thinks.
basically you get the chip and the downpipe (replacing the cat -
a good thing anyway) for your dosh. The best way to do this is
(alledgedly) to take your car to superchips itself and they put
it on a rolling road, and custom blow a chip.
I can type in some info from the literature if people are interested
(other than Reg - i'll send him the info). I notice HKS do a chip
upgrade of sorts - anyone got of them ???

Hmmmm....I can only speculate. I would (1) make sure the alignment was done
correctly (did it act this way between the time you put in the struts to
when you had the alignment done?) (2) Make sure everything is tight (strut
assembly, nuts at top of strut mounting, bottom, etc.), (3) are the tires in
good condition?
By the way, did you get the Illuminas? or the blue shocks? Really
have the alignment checked, try to get a printout of the alignment specs
that were done on your car. You may be shocked to see how off they may be.
The first place I went to after I put in my Illuminas had the car running
worse than when I brought it to him. He had the front left tire at .5
degree neg. camber and the right at .5 degree pos. camber. He said, "It's
within specifications.". Needless to say, I did not go back to him. Later,
I had the car aligned at a place that was in the boonies, but that was
recommended by fellow autocrossers who said that these other guys were
pretty accurate. They did a much better job and I was pleased. So it can
make a big difference. This car is very sensitive to setup, and is very
adjustable.
Hope this helps :^)

Matti,
What is the formula you use? Because I'd also like to know how much
hp is needed to accelerate an '85 MR2 from 0-60 in about 5 seconds, or a
little less. I'm supposing it would take not more than 230-250 hp,
factoring in that it only takes 255 for the 93+ RX7 twin turbo to do it in
4.7 seconds and that car weighs close to 3000 lbs, while my '85 MR2 only
weighs about 2400 lbs. And the rx7 isn't even mid engined, which is a big
plus for Mister 2.
Thanks,

Hi all,
Well, now that we've got to talking about computer upgrades, Does
anyone have any experience, direct or indirect with full replacement
aftermarket computers like the Haltech E5 or a similar computer? And how
much does a computer like this cost?

Guys,
I would suggest you check with Chris before buying any
parts elsewhere. His prices are pretty good, in fact I wish I had
known he was around before I started to modify my 4AG motor.
If you are looking for headers Dobi makes a pretty good TRD
imitation, in fact I bought their Tri-Y and it cost me around
$120.00. I also got one for my buddy's Civic and this cost $85.00
and is a replica of a Lightspeed. The only problem with them is that
you would have to order it now to get it by mid-summer but the price
is right. If you are interested I can get the number for you.
If you are going to put a cam bigger than 272you will definitely
have to modify the EFI as it will NOT idle. I put 2-288 cams in and
it would not idle anywhere even if I turned it up. I had to drive
with my right foot on both pedals until I figured out what to do.
If you are interested in this modification let me know.

All I'd like to know is can anyone else attest to this statement?

I don't want the ride to be very harsh as it is my daily driver. I plan to

Thanks - did you notice any improvement (other than weight) with the header?
What sort of muffler are you using? Did you eliminate the Cat (I killed
mine)? And did you notice any leanness after installation of the header?
The ignition amplifier - Jacobs. I did notice a small bit of improvement when
I installed it. Mainly right off idle the car was much smoother.
Unfortunately, I changed the cap, rotor, wires, plugs, coil and 86'd the Cat
at the same time, so it's really difficult to say what did what. However, I
installed a Jacobs box on my '87 F150 5.0 and it made a big difference in
mileage. An MSD6AL is cheaper and is comparable IMHO. I think the MR2 has a
pretty sturdy ignition right from the factory.

Hi Bruce,
I have an '85 MR2. Since you mentioned the TRD header, I thought
I'd mention that I bought mine from Select Sales in Miami, Florida for $250
and saved about $75. You can reach them at (305) 888-2828. If this number
is wrong, email me and I'll double check it. Just thought I'd help

I'd like to know how the car acted differently with the addition of
the Ignition amplifier (Jacobs). I'm planning on buying one this summer,
after I get my car fixed (had a small accident).

OK,
I have NO experience with poly on an MR2, but do have a lot of
expierence with them on my truck, a BMW, and a VW. In the truck, the ride
actually got better, since teh poly allowed the springs to work much better, and
eliminated some of the suspension slop.
In the BMW (which had SUspension Techniques springs, KYB struts) the
ride was slightly firmer on the straights (could be same, might be my
imagination...), but the control in the corners was 100% better... what I paid
for worked so much better (springs, struts, sway bars) so they definately were a
good inexpensive improvement.
On the VW, I just swapped to Poly bushings on the sway bars, so not a
complete change, but again the straights were un-affected, and bumps didn't
change a whole lot, but the cornering made a 200% improvement (since the old
ones were shot anyways, it was like night & day.)
Conclusion: Go for it, you notice a slight firming of the suspension, if
the bushings were totally shot, but al in all things will work to their fullest
potental.

I was told, quite recently, no one makes poly bushings for the MR2, and that
right now, TRD was the only source of bushings for the MR2 and they were hard
rubber, AND, they were unavailable. I just installed ST swaybars F&R (my '89
MR2 only came with a front bar stock) and they have noticeably improved the
feel of the car. I put 15x7 Borbet wheels and 205/50 A509's on at the same
time. Next step - Eibachs and Illuminas.

using cartest I pulled up the specs for an '86 MR2 (112hp?)
and tried the following:
0-60 4.7sec 250HP@6600rpm 260ftlbs@4800rpm clutch dump from 1100rpms
Gear ratios 1st: 3.17:1 4th: 0.97:1
2nd: 1.90:1 5th: 0.82:1
3rd: 1.31:1 6th: :1
Final drive ratio: 4.31:1
Car test weight: 2525 lb.
on 185/14R60's (the stock tire size) BTW this resulted in endless
wheelspin. With this power to weight the car could probably to
better. So I'd say 230ish and you're in the 5 second 0-60 area.

Hi aly, I have replaced every bush in my car with the polyurethane style
bushes (it's a 77 model celica) and i wouldn't say the ride is harsher
but rather that everything is much more direct. If your suspension is set
up properly bumps etc are taken care of by the shocks and springs. The
bushes are only there to provide some protection for the metal on metal
joints in the suspension system (a bit like cartilage in your own
joints). The advantage polyurethane has over rubber is a greater
torsional stiffness ie much harder to twist (plus it lasts heaps longer)
so it reduces the sloppiness (highly technical term) produced by standard
rubber bushes which distort more under stress and reduce the
responsiveness of the suspension. For those that care polyurthane bushes
come in a multitude of colours and can be custom made to replace any
standard rubber bush. Just my experience and i would never by a rubber
relpacement bush again.

About 440hp, depending on the shape of the torque curve. It's not just
the peak value, you know.

About 240hp, maybe slightly less if you improve the launch from stock
(should be possible with good tyres). Time to turbocharge that 4A-GE,
and there you go...
These numbers I got by using RevAnalyzer (for Amiga only so far
and only available as part of RevPro package which in itself is
free). Link is on my WWW page for more info.

I am not sure, I'm not sophisticated enough to put a number on it, but my
basic plan was to have a healthy streetable car. So the plan unfolds:
unshroud the valves a bit and clean up the head - nothing fancy - , a set of
yet to be determined cams (this is a plug for a suggestion), a TRD header
(that I just ordered minutes ago), and a set of individual runner throttle
bodies to feed the whole thing. At this point I am anticipating having to
fabricate the the individual runners from aluminum tube and plate that the
throttle bodies mount to, and use an existing TWM fuel rail and linkage. I
still have a hope (or delusion) that TWM will have something useable to avoid
that step. The whole thing controlled by an Electromotive/Haltech, etc ECU.
Otherwise, I have to develop some sort of plan to open up that stock EFI
manifold and find a larger throttle body. The goal here is to approach 175HP
to 200HP or so and keep the car streetable enough to be a daily driver while
I finish the "other" car. Then on to plan B - which is why the individual
runners. That's another story.

I had heard that someone was making a Weber setup for the 4AGE, but hadn't

Where, or better yet, how far into the boonies is this guy? I have yet to
find a good alignment guy here in Staten Island, NY, despite several
attempts. I've considered driving to Florida to see my brother to get a
decent job done (and it's a hell of an excuse to go on vacation). Anyone know
a good front end guy in Central NJ or NYC? I just replaced F&R ball joints
and front tie rod ends one afternoon last week and can't seem to get the
alignment job done right.

Hmmmm....I can only speculate. I would (1) make sure the alignment was done
correctly (did it act this way between the time you put in the struts to
when you had the alignment done?) (2) Make sure everything is tight (strut
assembly, nuts at top of strut mounting, bottom, etc.), (3) are the tires in
good condition?
By the way, did you get the Illuminas? or the blue shocks? Really
have the alignment checked, try to get a printout of the alignment specs
that were done on your car. You may be shocked to see how off they may be.
The first place I went to after I put in my Illuminas had the car running
worse than when I brought it to him. He had the front left tire at .5
degree neg. camber and the right at .5 degree pos. camber. He said, "It's
within specifications.". Needless to say, I did not go back to him. Later,
I had the car aligned at a place that was in the boonies, but that was
recommended by fellow autocrossers who said that these other guys were
pretty accurate. They did a much better job and I was pleased. So it can
make a big difference. This car is very sensitive to setup, and is very
adjustable.
Hope this helps :^)

4.7 sec 0-60 sounds a bit too optimistic for the RX7 TT. The mags I have
seen list it around 5.2 sec, similar to the NSX. In real world 0-60 races,
the NSX and RX7 are very close. After 80 mph or so, the NSX begins to pull
ahead. The NSX is rated at 270 hp and around 3000 lb. Sorry that this has
nothing to do with Toyotas...

I have the front/rear Suspension Technics sway bars on my 85 MR2 which come
with the poly urethane bushings (red in color). The car is stock otherwise.
The bars are almost exactly the same diameter as the stock bars. I did not
notice *any* improvement (reduced lean) with these bars, or any increased
harshness. The only advantage I can see with these bars are that they are
adjustable. Spend your money on the shocks, springs, and tires first, IMHO.
I was very disappointed in the ST sway bars for my MR2, compared to the ST
bars for my 1980 Celica. These were much larger than stock, and reduced the
lean significantly.

Subject: Next Holtville event
To: "mr2-interest@validgh.com" ,
Forwarded by Bryan Zublin (bzublin@gi.com):
I just thought you Californians might like to know about this event.
I was talking to Dave @ Dave Turner Motorsports (800-854-6640) and he
mentioned that the next Holtville Raceway event is going to be held
on May 11, from 2 PM till ? (a day/evening/night event). So here is
the deal if you want to put your car on the track and drive fast with
some other cool people (yes at the same time), here is your chance.
It costs $100.00 and you get lots of track time. It doesn't cost
anything to watch and talk.
You have to have a helmet and seat belts. Night running will require
functional headlights.
A fire extinguisher, roll bar, fire suit, window net, harnesses are
all recommended but not required. The field is usually broken into 3
groups 1) race cars : spec. first gen. RX7's and IT cars. 2) Regular
street cars : CRX, Integra, stock first gen. RX7's etc. and 3) Fast
street cars : RX7 turbos, NSX's, Corvettes, M3's etc. (I have gone 3
times so far twice in group 2 and now in group 3) Each group get to
run for 15-20 minutes. Then is called in and the next group runs. You
can come in and go out as you please during your session to check tire
temps, get a drink, let your breaks cool off what ever. This goes on
cycling through each group time and time again until we break for
lunch or diner in this case at which time everyone usually sits around
eating pizza while talking about there cars, the track and racing
stuff. (everyone usually pitches in for pizzas form town at the
beginning of the day ~5.00 each). After food its back to the track and
cycling through the runs groups again.
There is limited passing (front and back straight only) and corner/flag
people can wave aggressive people off to the pits, so I have not seen
any automotive contact as of yet, and I don't expect to in the future.
I do not want dents in my new RX7, nor do I wish to scuff a new NSX.
The event has not been crowded (last event had 26 cars total) and you
can usually find a time in your group where you are the only car on
the track. (by the way last event had 3 NSX's, 2 third gen. RX7's, an
M3, and various other interesting cars)
I can hit 110 MPH in a stock 3rd gen. RX7 so you can go fast.
If you go to watch, you will want to drive (especially if you go for a
ride in one of the race cars) so bring $100.00
Holtville is just past El Centro on highway 8 (1.5 hrs from San Diego).
The course is set up with cones on two alternate field runways all
concrete surfaces.

Just got an 88 camry and the muffler was replaced at midas before I bought it
Needless to say it's allready rusted out, so I'm looking to replace it.
I called around and found a place that would sell me an an
ultraflow II, installed, for $170. He said it was all stainless and
straight through pipes. I'm more concerned with the construction and
durability, than I am about the performance, but am warry since I know it
doesn't fit exactly to my car and some fabrication will have to be done
using aluminized pipes.
I also don't want it to be loud on the freeway, since it's more of a
commuter car. I'd really like something to help out in the low range,
but that will humm nicely on the freeway. Any suggestions are welcome.

I've done my own front end alignment for years and with primative
tools. Some thought, time and desire to do it right are worth more than a
$50,000 Bear alignment machine. For setting camber, level the front wheels;
you may have to drive one wheel onto plywood or something. Use a regular
carpenter's level against the tire. Do not center it on the tire because of
the bulge at the ground contact. By measuring the distance that the level
has to be moved out from the tire to read level, and knowing the length of
the level, you can easly calculate the camber angle(arctan). If you jack up
the car in the process of adjusting things, always roll it back and forth
several feet to level out the suspension before remeasuring.
There's a real neat trick for setting toe-in with a carpenter's square,
masking tape and a tape measure. I'll give you that one at another time.

I just secured a TRD header (chromed) from my brother in FL in "good shape".
We'll see. He got it from an IT guy he knows. Too bad I didn't get on the
list a few days sooner. Anyway, I was figuring on putting cams into the
motor, but haven't done much research on the 4AGE yet. The head looks like a
pretty good design as is. To date, I got rid of the cat and made up a 2 1/2 "
exhaust from the flex pipe back and installed a K&N. No other mods were made
to the motor yet. I figured the header won't change much, as the real problem
with the motor is intake restriction with the stock airbox, airflow meter and
assorted plumbing. I was figuring on variable potentiometers from the coolant
sensor to trick the ECU. The vacuum problem from a hotter cam is another
matter. I'm looking for a bit more than the stock cam, especially since I
figue they're getting round by now, but am not ready at this stage for
anything over 7500rpm. This motor has 113,000 on it, feels Ok, but until I
freshen it up, I don't want a statistic. Please me know about your
experiences in this matter, I am interested.

Guys,
I would suggest you check with Chris before buying any
parts elsewhere. His prices are pretty good, in fact I wish I had
known he was around before I started to modify my 4AG motor.
If you are looking for headers Dobi makes a pretty good TRD
imitation, in fact I bought their Tri-Y and it cost me around
$120.00. I also got one for my buddy's Civic and this cost $85.00
and is a replica of a Lightspeed. The only problem with them is that
you would have to order it now to get it by mid-summer but the price
is right. If you are interested I can get the number for you.
If you are going to put a cam bigger than 272you will definitely
have to modify the EFI as it will NOT idle. I put 2-288 cams in and
it would not idle anywhere even if I turned it up. I had to drive
with my right foot on both pedals until I figured out what to do.
If you are interested in this modification let me know.

Subject: Re: Magnecor Wires
Brian asked about carb tuning. I'm not the master, but here is my
best shot:
Tuning is kind of an art, or a soft science at best. Not only do you
have to fiddle with the idle and mixture, as you mentioned, but you
need to be checking the timing while you do it. Unfortunately, I am
not a guru at this, and what I do know doesn't lend itself to being
taught via email! If you think your timing is about right, let that
go. You want to set your idle first (assuming the mixture is rich
enough that the engine will run) then screw the mixture down until the
idle drops, then back off about half a turn. I think this is pretty
much the "standard line" about adjusting carb's.
Weber provides these instructions:
1.) With engine off, open the choke completely, by hand.
2.) Back-off idle speed screw completely (until the screw no longer
contacts the screw stop.)
3.) Readjust the idle speed screw to a point contacting the idle stop,
then proceed 1/4 turn further.
4.) Screw the mixture screw (needle valve screw) all the way in. DO
NOT FORCE!
5.) Back-off the idle mixture screw 1.5 turns.
6.) Start engine.
7.) Smooth out idle by moving the idle mixture screw in or out to
achieve the smoothest idle.
8.) Set idle speed to specified rpm and readjust mixture screw(s) to
achieve smoothest idle.
9.) Repeat 7 and 8 until a smooth idle at specified rpm is achieved.
Ok, yes, that is different than what I said in the first paragraph--
I'm allowed to have my own opinion, eh? (right or wrong...) This is
a bit trickier on a 38 DGS because of the dual mixture screws. I try
to adjust these at the same time and keep them exactly at the same place,
but this is kind of trickey.
I know that Koji is better at this kind of stuff than I am. Any words
of wisdom, Koji?

Dear Bruce,
The place is Brewster Tire, in Brewster, NY. He was recommended to
me by the head of the Westchester County Sports Car Club. A good handful of
people attest that this place does very accurate alignment to your specs. I
can get you the number for them soon if you like. They've mounted tires for
us before and done two alignments and I am pretty happy with their service
and prices.

If you only intend to put the poly bushings in the swaybar mounts, the harshness
when driven in a straight line will not be very noticeable unless the roads are
significantly rough, but cornering response will be more firm.
If you intend to upgrade other suspension bushings as well, yes the ride will be
more harsh since the stock rubber bushings absorb some of the shock, whereas
poly bushings tend to transmit it.

Here's something interesting I was told when I had a new front bar
installed, along with poly bushes on the links : (apparently) using
poly bushes on a bar of a certain width gives the same effect as if
a 1mm larger bar with rubber bushes is being used. Don't know how
true this is though.

I noticed slight top-end improvement with my TRD header - above 4300rpm.
I'm still running a cat, and I have a Monza exhaust on my car (not highly
recommended due to noise). I haven't noticed any leanness. Overall, I
wasn't impressed with what the header did for my car relative to the other
cars I've put headers on, mostly due to the better factory design of the
Toyota compared to these other makes. However, the combination of header,
tailpipe, and K&N open filter has given me more power on top than a stocker,
as proven in side-by-side comparisons with my friend's car.
Also, that number for Select Sales is correct. Ask for Steve.

I have a 1988 MR2 which came with only an 18mm front bar (no rear bar).
I have installed the Addco bars on my car (irritating story as to how
that happened...), which are 22.2mm front and 19mm rear. I noticed a
HUGE difference in the behavior of the car. It previously had absolutely
awful understeer, as set up by Toyota to protect the weenies who can't
handle rear weight bias, and this setup has cured most of that problem.
The car doesn't lean at all now (it is otherwise a stock suspension) and
it is much more neutral. I would suggest an ST front bar (21mm) set on
maximum with the big 19mm rear bar I have - I think this setup would be
ideal as the car still has a bit too much understeer for my taste right
now. I have also driven my friend's 1986, which is stock other than the
addition of a 1985 rear bar, and that car was set up much better from
Toyota. Thus, earlier cars may not need such a drastic rear end upgrade.
I felt the bars were a very good place to start for a suspension upgrade.
Just some thoughts....

I had/have a similar problem. On my MKI I had severe shimmying in the front
end. It turned out the tires on the car were never balanced from the
previous owner! New tires (A509s) solved that problem. I still have a "clunk"
in the front end on certain bumps that I believe is the steering rack. I've
eliminated everything else I can think of, including struts, wheels, rack
bushings, and tires.

Thanks - did you notice any improvement (other than weight) with the header?
What sort of muffler are you using? Did you eliminate the Cat (I killed
mine)? And did you notice any leanness after installation of the header?
--------------------
I have the TRD header in my basement to be installed this spring, along with
the HKS pipe and a set of 260 degree cams. I plan on doing the mods in
stages and will be posting the changes as I see them.

This is very interesting. I have the stock front and rear bars on my '86
right now, and with the A509s I like the understeer/oversteer characteristics
as is. I'll be installing light wheels with an old set of A008Rs this spring,
along with ST Bars (also in the basement... :) ) and hope to get even better
handling with reduced lean... I'll let you guys know how it goes.

I yanked all the intake plumbing off my '86, and replaced the right angle
inlet hose between the MAF and TVIS with a $5 rubber hose from the local
hardware store. This hose is only about 6" long, so it allowed me to install
a 6" cone filter I got from Select Sales. Now I have a direct shot into TVIS
with a HUGE inlet area on the filter. This is the only mod I was able to get
done before winter because of delivery problems with my exhaust. I noticed a
significant change in intake noise (which sounds pretty cool...) and for the
first time was able to *feel* the TVIS kick in at around 4200 RPM. I can now
hear the change and feel it.
Note, I'm still running stock exhaust right now (with a hole in it!!) and I
expect to see more effect when the TRD header and HKS pipe go on this spring,
and even more gains when the cams are installed.
If anyone wants details on what it took to put the rubber pipe in I'll be

--------------
I've driven Chris' 88 MK1 back to back with my '86, and I have to agree with
the assessment above. Before he put the ADDCO bars on his car, I took his car
out for a test run through a very familiar corner that I routinely "fly"
through in my '86. Chris was laughing hysterically after the turn as I was
stuffing my eyeballs back their sockets and sopping up the excrement I laid
in my pants... His car went STRAIGHT while my '86 would have taken the turn
with a slight initial plow followed up by the rear end coming nicely around,
and he's the one with the AVS Intermediates!!!
His car now (with the bars) doesn't lean much at all and has totally different
characteristics. I've yet to take it through that corner again... but I will!

Replace the rear bushings first. This will reduce some of the understeer while
stiffening the cornering response.

Check your CV joints. Grease around the outside of the rubber boots could
indicate a cracked boot, and thus contaminated bearings.
The "juddering" under braking sounds like a CV joint problem. How is it under
hard acceleration?

True. Rubber bushings don't allow the suspension to work as much. Just
swapping out the sway-bar bushings will give a very noticeable improvement in
cornering flattness, and using a different type at each end is an effective way
to tune handling if the bars are relatively well matched.

Hi list,
I am starting to have a problem with my steering, it is
getting stiff when I turn the wheel, only in places, but it seems to
be getting stiffer. I also have a rattling on the front end
somewhere, could this have anything to do with the steering ?
I have noticed quite a bit of grease near the left hand disc brakes
by the rubber boot on the driveshaft. It seems to be affecting my

The sensor tells the ECU how hot/cold the engine is to adjust the fuel
delivery to the motor. Cooler engine - more fuel, Hot engine - less fuel.
This is a gross adjustment, not a fine tuned one.
I just got my Mar/Apr issue of Grassroots Motor Sports yesterday, and they
have an article on doing exactly that. They're apparently way smarter than I
am. I was figuring on a Haltech meter (about $130) and a couple of 10K
potentiometers to obtain the full range of 0-20,000K that the sensor
provides. However, in the article, it says Select Sales if offering this
exact setup with their meter for $55. I'm buying it -it's cheaper than I
could do myself. When I get it in I'll post the results.

I am VERY interested in this "trick" or even more so with the Select Sales
unit. I read about this in the Toyota Performance Handbook and have been
wondering how effective it is. As for Select Sales, "Mad Man" Steve mentioned
he had something better but didn't elaborate (a first for him... if you've
talked to him you know what I mean...). I have their catalog but don't see
it there... hmmm... What is it called?
Oh, and by the way, a full description on the intake modification is
forthcoming... lots of interest!

Subject: MK1 Intake Mod
I've received several requests for info on removing *all* the intake plumbing
on the MK1, so here goes (this gets long)...
The MK1s have a rubber pipe that goes from the MAF to TVIS. On the 85/86 this
pipe is about 8-10 inches long and has a slight bend, on '87/88 the pipe is
longer and has two severe (90 degree) bends. This pipe can be replaced with
a single, straight rubber pipe about 6" long for around $5. Procedure:
85/86: Remove *all* the intake plumbing including the airbox, rubber hose,
MAF, filter, resonance box, etc. This will require you to remove a couple
bolts and brackets, disconnect the MAF, and (if you have air conditioning)
disconnect the vacuum line for the idle-up circuit (?). You will now have a
BIG hole where the airbox used to be.
Measure the inside diameter of the rubber pipe or the outside diameter of the
TVIS side of the pipe. If I remember right it's about 2.5 inches (65mm or so).
Go to your local hardware store -- I've seen the rubber pipes at Builder's
Square, Home Depot, and the local stores, so they're common. In the pipe
section you'll find several diameters of a rubber pipe with wall thickness
of about 1/4 inch (7mm) and about 5-6 inches long. Choose the one closest to
the diameter you measured... don't rely on the writing on the package, for
some reason a 2" pipe is really something like 2 3/8. It should be under $10.
The MAF diameter is about 1/4 inch larger than the TVIS side, so once you have
the pipe you'll have to MASSAGE (stretch) the pipe onto the MAF. This is
difficult because the rubber is stiff, but it works (stretch it with your
hands first, then work it onto the MAF in a circular manner). Clamp it in
place and go back to the car. The other end of the pipe will slide right onto
the TVIS.
Next you'll have to make some brackets to support the MAF because you've
moved it closer to the opening in the hood (higher in the engine compartment).
Simple brackets will work, and there are plenty of places to bolt them down
inside the engine compartment (thanks, Toyota).
If you have an '85/86, you'll need the adaptor to go on the end of the MAF.
This is a small cast aluminum plate that bolts to the MAF where the airbox
was and provides a round flange to mount your filter on. This can be bought
from Select Sales or Options (Chris, do you have this?). The '87/88 already
have this built into the MAF so you won't need it.
I installed the Select Sales cone filter, which *just* fits inside the shock
tower. This is a nice cone filter, but I suppose you could use K&N or any
other filter of 6 inches or less.
If you don't have air conditioning, THAT'S IT! You're done. It took me
about 1 hour. If you have air conditioning, you need to figure a way to
reattach the vacuum line. I haven't reattached mine yet (just unplugged the
connector that turns on the vacuum), but I'll be either installing a fitting
into the MAF flange (drill, tap, screw in place) or using the fitting from
the old rubber pipe, drilling an undersized hole in the side of the new
rubber pipe, and inserting the fitting there with an interference fit. I
don't know if this will work yet though. The fitting WILL work.
I think that's enough for now. If there are additional questions feel free
to ask. Chris Berchin removed all the plumbing from his '88 (significantly
different) so I'll ask him to post on removing that.

Subject: Air intake info
The number for Options is 1-800-678-2886.
It's been about 9 months since I did this...hope I remember everything!
If you have an 87-89, you'll need to rip out the ducting around the stock
air filter. Note that the intake actually passes through the front of the
trunk - you'll need to seal that hole or else your trunk will get wet.
I haven't found a good method yet for this, but so far 100mph tape has
been working well enough.
To remove the piece of the intake that goes through the trunk, you'll
need to remove the trim pieces in the trunk. Fortunately Toyota
used those little plastic re-usable pins, so this is easy.
You will have to unbolt the resonator box - there are 2 bolts that
hold this in. Be careful not to mangle any mounting points - I think
they will be good to use for relocating the MAF. Once you get this
out, you should be able to pull the hose leading into the MAF off,
exposing the flange that you will attach the new filter to. At this point,
I simply attached my K&N filter to the MAF - this required unbolting the
MAF to fit the filter on. Once the filter was on, I could only reinstall
2 of the 3 MAF bolts. However, none of this will matter once I relocate
my MAF in the same way Dave has.
There is still some ducting left in the trunk and right quarter - I haven't
yet removed mine (Ever wonder why golf bags don't fit in 1987-89 MR2's?
Now you know.), but I plan to this summer. When I do, I'll post info
on it. I figure the whole system is good for about 8lb minimum weight
reduction, as well as a major flow increase. My MR2 became much more
responsive with just this mod. I also got some cool intake noise.
If anyone has any questions, please drop me a line!

----------------------------
I bought the adaptor plate and filter from Steve at Select Sales about 6
months ago. The filter is one they developed themselves through their
development wing of the business. Mine has a plastic cone center and a
material similar to K&N on the outside... This funnels the air directly into
the MAF. I talked to Steve the other day and they have a new version of the
same filter that puts filter material where my plastic cone is. This gives
you much more breathing area than I currently have.
I *think* I paid around $110 US for the filter and adaptor. I don't know
what the current price is or what they are separately (just the filter). My
friend Chris bought the plate from Options by mistake (didn't need it in his
'88) and it was roughly $40. Clamps are included.
The filter looks **really** cool, and works just as well. It's positioned
RIGHT under the hood vent and can be seen from outside the car if you look for
it. Downside? No protection from the elements (rain), but not much goes in
there when you're driving. If you wanted you could make a deflector shield,
but that would limit the amount of fresh air you get from the vent and
increase the hot air intake from the engine bay.
There ya go! A long winded answer to a short question. Just ask for Steve,
mention the sytem (and me if you want)... he'll know what you're talking
about. I believe they're calling their filter the "Powermax."

Uh, uhm, ..the Select Sales dash mounted digital air/fuel gauge with
potentiometers. I also noticed they've got and add in GRM for something
called the "MapFueler" which is a user programmable injector driver that
works in conjunction with the factoru ECU. It sez "from $269 and up"..and
looks like a pretty neat device. Another thingy I saw them advertising was
the "Superchips ICON" supplementary computer which lists at $295.It doesn't
look programmable. Anybody have any experience with these goodies?

Looks like the weather is supposed to be nearing 10 degC (50 F) this
weekend, so it'll be warm enough to go into the unheated garage and
slowly start playing. I'm going to be tearing everything apart first
(since I can only afford to kill one day this weekend), so I can start
figuring out all the bits that'll require fabrication work (trailer
hitch, intake, brake ducting). The first actual changes I'll make are
the front bushings, since those are the ones that are questionable
(packaging indicates that they will NOT go on a '91 or '92), but we don't
believe the packaging :-) Doubt I'll get to it this weekend, but likely
in two weeks.
First event is April 28, assuming winter has left us (it was -27 degC,
-17 F in the morning yesterday), so I need to get all the work done by
then. Once the autox season gets into gear, I don't have a lot of time
to do any extra work, so I try to get it all done in the off-season.

>computers like these? :^)
They are usually critical if you are trying to squeeze every last
living, breathing HP out of an engine, but kinda pricey otherwise.
When I build my ultimate Celica (my life's project) it will have
a MoTec computer. This approximately $2000 mother of all engine
controllers is one sexy package. Here's some info:
MoTec M SEQ-P Engine Control Unit
=================================
Motorola 32-bit Processor (33MHz)
Programs via Flash Prom (In-Car Programming)
840 point fuel matrix
840 point spark matrix
User Defined Speed Density, Mass Air Flow, and Throttle Mapping
10 bit A/D converter
6VDC-16VDC operating range
Asynchronous TTL Microwire serial port
1-12 Cylinders
2 or 4 stroke
15,000 rpm max
8 sequential injector drivers, 4:1 peak and hold w/switch mode
Ignition Timing 0-51 degress with .2 degree (crank) resolution
4 user defineable logic outputs
Input for knock sensor
Boost, Idle Speed, and Lambda Control
Max 512K SRAM for On-board Data Logging
Data Logging of 5 samples/second of 38 channels for 12 minutes
Radio Telemetry ready with addition of radio modems
Once you've got all this stuff, it would be really nice to see all of
this, right? The controller includes PC software called Graph View
which is just absolutely awesome! It looks like a really cool virtual
dashboard. My ultimate goal is to find a way of embedding a Color LCD
screen into the dashboard and using this as my guages. The intended
purpose is to give you a recorded playback of the data stored in the
SRAM mentioned above.
Graph View Program includes display of:
Vehicle Speed
Engine Speed
Gear Selection
Fuel Octane
Throttle Position
Clutch Slip
Lambda (Air/Fuel Ratio)
MAP/EMAP
Fuel Pressure
Fuel Tank Level
Engine Temperature
Air Temperatur
4 Auxilary Inputs (User Defined)
Battery Voltage Level
(Um, some of these are guesses from looking at the small amount of
literature that I have.)
BTW, that $2000 covers _none_ of the many parts that you would need
to install and acutally use this beauty--sensors, actuators, injectors,
solid state electronics, etc.
But I digress--the subject was HalTech. I have literature on several
different HalTech products. Here is some of it...
HalTech Products
================
F3 and F7B Engine Management System
-----------------------------------
If you're looking for an inexpensive system to feed a non-forced induction
engine, the F&B system is for you. The F7B is a throttle position
controlled injection system. If your application includes a turbocharger or
other forced induction unit, manifold pressure must be used as the primary
load sensor. The F3 system computes air flow based on manifold absolute
pressure and engine speed. The F3
can also be used to drive an throttle position controlled (naturally
aspirated) engine if you need more than the F7B's limit of 8 injectors (the
F3 can drive up to 16.)
E6 Engine Managment System
--------------------------
The E6 System is the optimal programmable fuel injection system. This unit
manages both the fuel and ignition timing requirements of an engine. Like
the F3 system, it can sense engine load using either manifold pressure or
throttle position. However, for manifold pressure readings, the E6 uses a
more accurate and faster response pressure guage than the F3, and rpm
resolution is doubled.
IG4 Ignition Timing Computer
----------------------------
A standalone fully mappable ignition timing computer. Programmed in a
similar fashion as the F3, F7B, and E6. Can be used with a variety of
ignition systems.
F5 Supplementary Fuel Injection Computer
----------------------------------------
A supplementary fuel injection computer for control of additional injectors
for turbo or supercharges engines. It can be used in conjunction with a
carburetor or OEM computer. Can also be used to manager the injection of
water or methanol in turbocharged engines.
Retail Prices as of May 1994
----------------------------
F7B for 1-4 Injectors......................$802.00
F7B for 5-8 Injectors......................$842.00
F3 for 4/6/8/12/16 Injectors...............$883/915/948/1166/1304
E6 for 4/6/8 Injectors.....................$1450/1482/1515
IG4........................................$640
F5.........................................$350
(Plus necessary wiring harnesses, etc.)

Yes, I'm afraid that is pretty much true, as far as I am aware. You
can get Sway bar bushings and endlinks made out of poly, and this is
useful. You can do like the original owner of my Mazda 323 did after
he drove this then brand-new 86 from the port--take all of the suspension
pieces, off, toss them into a fire and burn all of the rubber out, then
take them to a machine shop and have custom brass bushings machined for
about $100 a whack! Not the cheap way out, ride is like being drug
down a pothole-filled road in a wooden box, but I've never been in
ANYTHING that would corner like that baby! Of course now, 80K miles
later, the brass bushings are long gone and replaced by new stock pieces
with rubber bushings again. Hmmmm, memories!

The S/T rear bar requires a small bracket be installed on the lower spring
perch. The recommended drilling a hole and bolting the bracket on. I thought
that was a little cheesy, so I welded mine on. Anyway, the threaded rods and
spherical rod end bearings the S/T bar uses may be a better way to go than
replacing the struts and buying the Toyota links. I'd think it'd be easy to
duplicate the link design. Pretty much any race supplier carries spherical
bearings rod ends to make your own links (I used a lot of stuff from AFCO
when I was fooling aroung with suspension links for another car a while back.
I'd guess that'd be a much superior way to have end links than with urethane
or rubber insuated links.

Subject: Re: rubber vs. poly bushings
To: mr2-digest@cyberspace.cyberauto.com, Toyota-mods@cyberspace.cyberauto.com
Assuming that on a car with all else kept constant, the distance between the
frame mounts is 100cm, and with a bushing thickness of 1.5cm around the bar.
Take a hypothetical compression of 1cm for the rubber bushing under full
cornering load (a reasonable figure I think), and .125cm compression for the
poly bushing under full load.
Consider that under full load the bushings on each end will be fully compressed,
giving a combined total of 2cm and .25 respectively.
From these numbers, the rubber bushing is allowing the swaybar to slosh around
1.15 degrees to each side from level.
The poly bushings on the other hand force the bar to work sooner by only
allowing .14 degrees of total slosh from level to one side.
This is a difference of 1.01 degrees between the two compounds for straight line
vs. steady state cornering. The combined difference for cornering from side to
side is 2.01 degrees. Of course this may or may not translate to 2.01 degrees
difference in body roll due to spring rates and other minor factors, but the
reduction in roll is noticeable.
A larger bar will obviously provide more roll stiffness, but some tuning of the
bar can be done by using different bushings either at the frame mounts or the
end-links. With two swaybars in use, this gives a range of 16 different
combinations of bushings for fine tuning the handling.

I have an extra set of strut carriers that DO have the mounts on them. I
doubt I will have use for them, so if anyone has an 87/88 and wants to
install the rear bar "cleanly" let me know. We could probably work out a
deal.

Bruce,
Thanks for the plug! :) It sounds like your car will be very similar to
mine this summer. I'll have the intake, TRD header, HKS pipe, potentiometer
(or Select Sales gadget) for tuning fuel flow, and a set of Chris Meyer 260
degree/7.6mm lift cams. It will be interesting to see how we compare.
I'll be posting the effects of the 260/260 setup. My going in position is
that I won't need to do much except put them in and maybe adjust the fuel
flow. I expect a good idle and better response... we'll see.

I was hoping for the 130-140HP range or so, depending on how I degreed the
cams. I'm expecting soemthing much crisper than what I've got now. As a

Hello List!
A few months ago I asked if anyone had ever taken weight off a stock 20R
or 22R flywheel. I dont think anyone had, or replied on the 20R flywheel.
I wanted the quickness a lighter flywheel provided, but did'nt want to get
off my wallet to the tune of $349 for a 9 lb pound aluminum one from LC eng!
Nor did I think the 9 lb would work well for a street car with the stout
camshaft that is being installed (280/280 480lift). You would imagine it
would beat you to death at idle and be way to jerky on and off the throttle,
because the car will decelerate much quicker also. Anyway, the trick I heard
through the grapevine was to cut the large ridge off the backside of the
flywheel. The stock flywheel weight is 22 lbs. I wanted to try and get five
pounds shaved off the backside without even messing with the face of the
flywheel. That would leave me with a 17 pounder without alot of trouble.
Well I can tell you the ridge is worth about 2 lbs, an important 2 lbs
beacause it's out at the edge of the flywheel, the other 3 lbs I got off the
back by countersinking the flat part. You may be able to take another pound
or so from the backside but I'd like to keep my bellhousing intact for now!
For about an hour on the lathe you can lighten the stock flywheel by 5 lbs
easily and keep your money!
Do ya think 5 lbs will make a difference? Later!

Heim-joints are quite common on more upper-end sports car. Trying
not to detract from the Toy_mods list... but I gotten into an accident
recently in my 3rd gen RX7 (which required 3.6k worth of suspension pieces)
and lo and behold the rear suspension was done in Heim-joints with a rubber

Nope, I'm still looking for the cams I want (hint for Chris Myer) and looking
for a head to work on. Are the shims he's looking for unusual sizes? However,
I've had good luck getting everything I've needed from Price Toyota, Newark
DE. I just called them and they confirmed all the manufactured sizes are
readily available from Toyota. They advertise in the back of car mags. I've
ordered stuff from them for years. I've never had luck with the local
dealer.
Makes me wonder where my old 22R pickup is now?

Hiya all,
The computer I use in my AE-86 is (Like the Haltech & Motec
systems) a local Australian-made device, though by no means is it as good as
the other two brands. The only advantage my Microtech D4 has over the others
is that the fuel scheduling can be completely re-adjusted as you drive -
without the need for a computer at all. What the Microtech has got is
screwdriver adjustable points to control how much fuel goes in when, eg, at
idle, just off idle, mid-range, top-end, the transition from off-throttle to
on, and so on. When you buy the computer you tell the dealer exactly what
has been done to your engine and he pre-programs the initial base paramaters
into it, then when the unit is on the running engine the screwdriver
adjustable pots are used to 'fine tune' the fuel scheduling. This means that
the same computer can be used for reasonably similar engines without any
great dificulty, or, in the case where you might change the cam or
manifolds, etc, you don't have to return the computer to the manufacturer to
get it reprogrammed. Very handy.
The fuel scheduling is good, but not quite as good as a Haltec or
Motec (Did everyone know these are made in Aus??) because Microtech have (by
necessity) had to assume a general volumetric efficiency curve. This means
that occasionally at certain points the engine may get a little too much
fuel or a not quite enough.
One function of the Microtec that's rather handy is that you can
quite quickly go from what I call 'economy mode' to 'grunt mode' - all you
have to do is grab a screwdriver and raise the rev limiter up from, say,
7000 odd to 8500, and reset the '+ - 10% fuel trim' pot from '-5%' (where I
have it normally) to '+10%' to get an overall +15% more fuel. I have found
that with my 4AGE doing these to things I can get about another 15 hp from
the engine at high revs. Ok, that's using the 'seat of the pants dyno
system', but there is no doubt that there is a noticable increase in power.
(I also don't get 38 mpg any more ;)
The Microtech is by far the cheapest computer (Aus $700, about
US$550) because they quite fairly assume that if you are replacing the
original factory box with a Microtech then all the original sensors will
still be on the engine, so that's what it uses. You have to wire up the
Microtech loom to the old sensors which live in their original positions.
The other two manufacturers include their own sensors that you have to fit
onto the engine.
Ok, the down side. It doesn't control spark timing. This means that
on my 4AGE I have to run a fixed spark (about 26 DBTC) which isn't _really _
a problem, but a couple of things suffer slightly - the top & bottom end
power could be better with a moving spark. I don't have enough advance at
high revs and too much down low. (Idles like a ported rotary :) The fuel
economy also suffers slighly from not having enough advance at cruising
speeds. Microtech are soon (been waiting nearly 2 years :( ) a spark control
module that plugs into the side on the main computer box.
The Microtech has two ways of measuring airflow into the engine -
the normal MAP sensor method, or as in my case by simply measuring throttle
position. Air Flow Meters are not supported, but that is not important in my
case (at least) because Aus 4AGE's use the MAP system instead of the crap
AFM system. (Why on earth would you use an AFM on a performance car
anyway??) I had to use the throttle postition system because I don't have
enough vacuum down low with the 288 deg cams to make the MAP sensor work
properly. (or the brake vacuum booster, sometimes :( )
So there you have it, the ups & downs of Aftermarket injection. Hope
it has been of some interest.
The B Man.

Hiya all,
There's an even easier way to do it. In aviation we have a fairly
accurate (up to a point) way of measuring small angles and calculating
heading changes quickly & easily. It's called the 'One in sixty rule', and
without going into the gorey detail as to how it works, it is used like this -
If you are travelling 60 miles and you find that you are 1 mile to the right
of where you want to be, then how far (in degrees) have you gone off track?
The answer is 1 degree. If you'd only gone 30 miles, then it'd be 2 degrees,
15 miles 4 degrees, and so on. What is the use of this?
If we measure a distance of 15" vertically up the side of the wheel
and use a string with a bit of weight on the end (bottom end!:) to measure
the difference in distance between the two points, then we can very quickly
get an accurate camber figure. Eg, if the upper point 15" above the lower is
1/4" 'in' (negative camber), then you have 1 degree negative camber. (If you
measured points 60" apart, the difference would have been 1"), 1/2" would be
2 degrees, 1/8" is 1/2 degree, etc.
Very bloody easy.
The B Man.
P.S. Don't forget to stay clear of the bulge in the lower part of the tyre. :)

Subject: Valve shims & where they live.
Hiya all,
There's been some mail regarding valve shims for 4AGE's. I've just
done the clearances on mine, and after shuffling a few around and borrowing
a couple, I found I had to buy four new ones. The local Toyota man wanted me
to wait a couple of days and charge me lots (Aus$13.50 each) for the
privelidge. I went elsewhere.
My travels took to a Honda motorbike dealer, who had some shims of
the thickness I needed, but for less $$. Ok, only _slightly_ less,
(Aus$12.50 each), but it's one to remember.
As for the thickness, he had them up to at least 3.3 mm's, so that
should keep you out of trouble.
To the guy who needed the 3 - 4 mm shims - what on earth has been
done to your cams? Have they been reshaped with a file?? There is only ONE
(That's 1, 1.0, uno, eins, etc) way to get bigger cams from smaller cams -
they MUST be built up with the stellite process. If you get the old ones
ground down to give more timing, etc, you will effectively lose lift. The
4AGE doesn't need much lift, (my cams are only 0.295") but it's a real
butchers job doing it the cheap way. Do yourself a favour and get it done
properly, or get some decent billet cams from a reputable source.

-----------------
I picked up a set of custom rims. They're 3-piece with the centers milled
out of a solid piece of aluminum... quite nice!! The rim pieces are by
Compomotive ($$$). These are one of a kind.
Anyway, on my digital home scale each wheel/tire combo weighs in at 27 lbs.
The tires are Yoko A008R with about 2/32 of tread left. That saves me 3 lbs
per wheel based on a 1989 wheel... anyone out there with a 1985/6/7 wheel
that's loose? I could wait for my car to come out of storage to weigh mine

I'm planning to use TWM throttle bodies. They basically fit anything that can
take a Weber style manifold. I've seen them on Honda 1.6 motors, and they
work well. The drawback is that they're MUCH money. Isn't that always the
case? Someone else, a few days back, posted a note that the Toyota Atlantic
guys runs a similar setup. I'm figuring they're running a much larger bore TB
than I will since they get around 240+ HP from those engines at far more RPM

Subject: Re: 4AG cams
Hi all,
It would seem that a lot of guys are interested in putting
288 cams in their motors from the feedback I have recently had
and would like to know how it works. I would have to say that it
works pretty well on the street but the motor is happiest on the
highway. In stock form the motor is no slouch but I have found that
other small engines in its class can keep up with it from about
80-110 mph. After this it can pull away as few small engine cars can
do 140 mph, also few big engine cars.
With the 288 cams my motor makes a bit more than stock power
up to 4500 rpm when the cams come in with a burst of power and it has
surprised many on the highway up to Ford Probes and Eagle Talons. I
haven't been racing anyone in a while as I need to change the front
stuts which all of a sudden went south.
For those of you interested in how I got it to idle, this is how
I got it to idle. First of all I knew someone who had already done it
so it was just a matter of sticking to my guns. Also I had no choice
because it would not idle reagrdless of how much I tuned the idle
screw. What happened here is that the motor was starving for gas
and this is remedied by tweaking the airflow meter about 3 turns
counterclockwise I believe. The next thing to happen is that the
motor would not make any power below 4500 rpm and this is caused
by the EGR valve weakening the mixture by returning some of the
exhaust gas to the combustion chamber. The fix for this is to disable
the EGR valve and I believe this mod is good for unmodifed motors
which have a slow pickup. I have also tried the pot in the temp
sensor line but did not notice any appreciable change in performance.
I would have to say that these mods should only be done on a motor
without a catalytic converter as excess unburnt gases may cause it to
burn up.

I've been impressed lately with all the talk about
Lexus injector this, RX-7 injector that, chip this,
chip that, potentiometer this, pot. that...well, I'm
hoping I could get a few comments about stroking a
22RE. I've noticed that there are no performance
catalogs that offer a stroker kit for this fuel injected
engine and I've heard that there was once(no longer in
business) a company that did but only for the carburetor
version. So, my questions are:
o Will the ECU be thrown off by the longer stroke?
o Would I need different injectors?
o What else might be effected?
I would appreciate any an all comments; opinion or fact.
Thanks,

Can I suggest staying with Toyota, Honda, or Mitsubishi? If I had to sell
my MR2 for a more "passenger oriented" performance car that would still be
great for autocrossing, I'd go with a '90-'93 Acura Integra GS 4 Door (make
mine light blue metallic please :-) ). I think it's such a good looking
car (the 4 door) and I checked the Options Auto Salon catalog and
found that everything that's available for the MR2, performance wise, is
available for this car as well. You can even get Tokico Illuminas which
aren't even available for '86-'89 Celicas or '86-'95 Legends (two other cool
cars as well, IMHO). Put this car with the '85 MR2 and a '90 CRX Si and
you've got one incredible fleet of three.
I apologize for rambling on,

Nope..as far as I know, its all top shelf, top dollar stuff that belongs in

really expensive stuff at this time, and will be for the immediate future. If
I'm not mistaken, Toyota Atlantics were once running Webers and are now

I agree with you Steve. But I'm looking for a little change. If I had
an '86 MR2 and this '85, then I'd leave the black trim alone. But since I
only have one, I want to make it as desireable as possible.
But don't forget, I haven't done it yet. I plan on getting the front end
body parts in May (just in case you didn't hear, I had a small run in with a
Jeep Cherokee in July '95) and having the entire repainting done by the end
of June (God willing). So it's not set in stone yet. I may go with a
combination between the '85 and the '86. To get an idea of that, check out
the image of Bikram Bakshi's '86 MR2 on the who's who list for what I think
would look great (on the www archive). He has the bumpers and spoiler red
like any '86, but instead of the red side skirts, he has the black triangle
like on my '85 in front of the rear wheels. I will leave the door handles
black. I have the front end mask with "MR2" and the mr2 eagle symbol
beautifully stenciled in. Any ideas are appreciated for making the ultimate
mk1 MR2. Also any parts anyone wants to sell (in good condition) are
welcome. (like the rear wind deflector, red rubber strips under headlights,
red rubber/plastic chin spoiler under front air dam, red side skirts under
doors, red mud flaps, etc.).
Thanks :-)

True, but note that I'm referring to the non VTEC motor and the fact that
the car would be used also. Kind of drops the price to about $10K now. I'm
suggesting this car if you Need to have a car with four doors as opposed to
a Dodge Neon.

Using a manifold air pressure (MAP) sensor instead of a air flow meter (AFM)
is probably cheaper *and* will result in reduced restriction (more hp). The
Mk1 MR2's in the US all have the AFM, and the Turbo MkII's also have the
AFM, while the NA MkII's have the MAP (I think this is correct). Why didn't
Toyota use the MAP on all vehicles for all countries? Might have to do with
the US stricter emissions requirements, although Honda has been using the
MAP for their EFI since the beginning (I believe).
Switching over to the non-US MAP system for the Mk1 sounds like an easy way
to pick up a few hp. Aren't the UK / Aus Mk1's rated slightly higher than
the US Mk1's? Are there any other differences in the engines to account for
the different rating (like increased compression ratio)? Yeah, yeah, I
should check Matti's web page...

Dear Bryan,
Which motor is this for? I'm sure you're not talking of a 4AGE,
I know 94mm pistons wouldn't fit. Do they list any stroker crankshafts for
the 4AGE? If they or anyone else does, a price like that could make me
think of stroking my 4AGE a few years from now. $1700 for an HKS crankshaft
and $4500 for an HKS stroker kit installed on a 4AGE is just a bit ridiculous
in my opinion. Did I forget to mention that TRD wanted $3000 for a stroker
crankshaft? Whoa, Nellie!

As a note, another really nifty thing that having a MAP rather than
a AFM is that it will allow anyone to just bolt a high-flow K&N filter
right in the place of the stock air box. With the AFM, you can do
this, but you have to deal with getting air through the AFM--big
hassle compared to just tossing the whole box out and bolting on a
big K&N cone.

I've been looking to improve the performance of my '92 Celica for more

Well, yesterday I was leafing through the Toyota Performance Handbook
(I've never bought a copy since it's sort of out of date and only

targets earlier Toyotas) and I suspect I understand.
I came across a mention that if I have a front wheel drive Toyota, I
might have problems boosting its power. The Handbook used the "new"
FWD Celica that Toyota had come out with (I believe it's referring to
the '91). It says that the engine in the car develops 135 horsepower
(that's the 5SFE like in mine) and that that's about the limit of what
Toyota's front wheel drive train can handle. It said that to handle
more torque they had to go to all wheel drive in the turbocharged
version. The Performance Handbook said that you could probably get the
FWD version to handle 160 HP, but that would be pushing it.

Hey Roy,
Don't feel so bad. Put a smile on your face. :-)
I also have the Toyota Performance Handbook and I remember reading
what you mentioned. I believe that if you speak with some people in your
situation, they can help you overcome any problems that might occur with
high power and front wheel drive. I don't see why it wouldn't be able to
handle some high power if it's done right. After all, a new Eclipse GS-T is
front wheel drive with 210 hp! There will be wheelspin, just look at how a
CRX Si with 108 hp spins its wheels at an autocross (still love that car
though). There will also be torque steer. But any of these problems can be
overcome or managed. I take what I can from the Toyota Performance
Handbook, there's some good stuff in it. But I've also found some
inconsistinces in it that should be taken lightly. Check out the page with
the Corolla GT-S I believe where the book states in the caption under the
picture of the wrapped header, "Foil would quickly melt around header pipes.
Note the extensive use of foil around the headers". Just remember that, yes
there will be some obstacles in your modifications, but not everything in
the book is absolute. Going to all wheel drive in the turbocharged version
was an added incentive to the extra power. But I don't believe it's
mandatory. Check with some performance shops and others on this list and
I'm sure you'll get some answers and ideas.

rubber triangular piece in front of the rear wheels, that would stay black
as it is right now. If I bought the ground effects (I personally prefer the
term "side skirts" :-) ) they would be red. These are the side skirts that
came with the "aerodynamic spoiler package". They eliminated the small
black triangle and added a color keyed piece the length of the wheelbase
under the doors. The majority of '86-'89 models I've seen have this piece.
They were apparently available in black on the '85 Japanese home version as
seen in a late '84 issue of road and track. I like them color keyed
personally.

I agree. This is what I will probably end up doing. I have no intention of
painting the door handles, window trim, trailing edge of the sail panel,
rear fascia, etc. red. I will leave them all black. What I'm cosidering is
painting the bumpers and rear spoiler red, just like on an '86. The '85
model had these pieces painted black. Kind of like an early Porsche 911
turbo.

I have to agree. I generally don't like silver cars, but the silver on my
'86 has held up beautifully to the elements and looks really good! I have
the side skirts on mine though, which I really like. From my digging around
for parts cars and general interest, I've noticed that most '86 MR2s are
pretty loaded and have all the skirts, wings, dams, pwr goodies, etc. They
started stripping them in '87 and '88 (cost?) and had the black treatments in
'85. I'm sure someone out there has all the gory details of options...

The 2.6L stroker that LC Engineering sells is for the 22R series of engines.
They only sell parts for the 20R and 22R series engines. I think they are

Bruce,
I believe the supercharged motor for the MR2 and the 88 on
GTS Corolla had larger main and con-rod bearings. The piston pin
is also larger. Someone had told me that there were 2 types of heads
also, however, I never did find out about that.
Hope this helps.

I wouldn't mind it being on the mods list, but I'm okay with it being posted
to the mr2 digest. Either way is fine with me. I'd love to hear about it.
Also, if anyone has any experience removing the bumpers, fenders, air dam,

want to start removing the front body panels soon to prepare for the front

There is much more than meets the eye, from what I've gathered. The
cars do not share con rod or main bearings (not sure which one - I think
it's con rod). The later years had a wider bearing, I believe. You
can determine which is which by looking at the listings for things like
Carillo rods, pistons, etc. The 1985-86 have one part, the 1987-89 have
another. Aside from that (and the cam cover lettering!), I haven't found
anything else other than the pre-1987 were rated at 112hp (in the USA), and
the later cars were 115hp.

So, one would figure a later block a smidgen sturdier than an earlier
block...or am I a little to presumptuous?

Bruce,
I would tend to believe that the heads are interchangeable
and the only problem would be the manifold. I had posted
earlier about the crankshaft and after cross-referencing the 4AGE
and 4AGZE information I have found that the main bearing journals
are the same, however, the con-rods are not the same and the top end
is definitely not the same. It seems that starting in 1988 with the
4AGZE motor they beefed up the con-rods. This was subsequently
carried forward into the next generation GTS Corolla. On the subject
of crankshafts the journals for the main and con-rods are the same as
for the 3A-C, 4A-LC and 4A-F series engines. It therefore comes to
mind that these crankshafts might be the same. Anyone??? Bill??
On the other hand, if these cranks are not the same but have
different offsets then with suitable connecting rods they could be
suitable as factory stroker cranks thereby raising cc and bhp.
Just my thoughts.

TRD did, at one time, supply 5 different gearset for this car, ranging
in price from $1900 to $2700. What they supply now is _anyone's_ guess.
They are alleged to be putting out a new catalog in April, but I'll

714-444-1188. Give Chris Hines my love and tell us what you find

There is also a difference in the head between the 88-89 and 90-91

Well, Chris, from my many months of lurking I know that you are the one who
deals with aftermarket merchandise. Is there no one else that builds or
markets close ratio transmissions?
I don't necessarily mean only for Toyota, but for any other Japanese car.
I'm thinking Suzuki in particular mainly because my friend has a Suzuki
Swift rally car, and I have a feeling that this is the car that he will
transform into an SCCA racer.

Yup, for an average RWD car you could use 25%-30% loss. For a FWD, I think
25% would be about right, and a 4WD up around 30%-35% I'd reckon.
FWIW, the most efficient would probably be a Top-Fuel drag car - they have
no gearbox, only a computer controlled six-stage clutch and a live axle diff
- 10%-15%?? (neglecting tyre drag)

Um, not to my knowledge. In the Japanese performance world, there
seems to be a factory sponsored performance group (or groups) that
carry the only really hard-core performance parts for the individual
cars. Actually, I should say "design or market" instead of carry.
For Toyota, you have Toyota Motorsports and TRD, Nissan has Nissan
Motorsports and Nissan Competition, etc. I am open to correction
here, but I believe that the Motorsports group does all of the
factory's racing effort, and designs parts for their race cars,
but doesn't market these. TRD and Nissan Comp design the parts
and market them, but they don't focus on racing themselves.
Anyone want to help me here? Good spot for Koji to jump in...

(not easy with a TRD LSD pack!). Lokked under the bonnet to find the harmonic
balanced had broken the keyway, spun and removed the bolt. The remains of
the key had got so hot that I couldnt get the belt pully off. I got a new
pully but how to get the old key out? For the first time in 17 years I
had my road car towed home. My wife laughed as she drove home in her new BMW
that never breaks down, asked why I drive a 12 year old pile of junk! I never
did pick up Chris's CAMS, I will when I figure out how to fix this problem.
Swapping to a new engine is looking easier. In the mean time I'm staying
at home because I cant stand what my wife is going to say if I borrow the
keys to the BMW.

I'll let Dave answer that, but the smaller surface area will give more
pressure against the flywheel. Pressure=force/surface area.
Centerforce discs have little triangles cut out, and are not fully

I was just talking to John Broderick at MR2 PP, and he was telling me they're
fooling around with an variable exhaust much like the Yamaha EXUP motorcycles
of the late 80's. I believe he said they're still in the experimental stage,
but they worked on the FZ's I used to ride. I think he also said they're

No, not a dumb question. Besides the P=F/A situation, the light flywheels
are available only for the 200mm disk size. This is true (to my knowledge)
for both the TRD and HKS flywheels. Thus they're only available for the '85

The conversion would be more like: $1280 CAN = $934 US
or $1600 CAN = $1170 US
ie. exactly opposite (roughly) of what you show.

Hi all,
On the subject of bored out throttle bodies, I found a
machine shop here in Canada that did mine for me. It cost me
$150.00 and I am pleased with the work done. Not any machine
shop can do this sort of work as in addition to enlarging the
bore and replacing the butterfly, the intake side has to be tapered
to suit or the flow would be impeded.
I would have to say that this is one of the best mods I have done
and leads me to believe that tweaking the AFM, disabling the EGR
valve and installing a bored out throttle body with a free-flow
exhaust and good air filter would net something like 15-20 hp on
the 4AG motor.

Subject: Re: 4AG cranks
Cc: toyota-mods@cyberspace.cyberauto.com
Bill,
In the Datsun 240/260 motors the difference in cc is made with
the crank. The stroke is longer for that from the 260 motor and just
putting a 260 crank assy in the 240 brings it up to 2600 cc from
2400cc. This information has been documented along with other
stuff pertaining to the interchangeability of parts between the
various models. In these motors the thickness of the walls between
cylinders is such that the 280 pistons can be put into the 240 with
the crank bringing a 240 up to 2800 cc or even overbored to 3.1l.
In the 4AG motor the thickness of the wall between cylinders is
such that overboring cannot give a significant increase in capacity
and that is why I was suggesting to the list that there could be a
chance of a crank from another Toyota motor working in the 4AG
motor as a stroker crank. With an increase in stroke the 4AG motor
could put out an extra 25-30 hp, however, I am not going to put
out $2,000-3,000USD for a TRD stroker crank and would
anyone else on this list if we could walk into a junkyard and come
out with a guaranteed 30 hp? All we need to do is some research
to see if Toyota is like Nissan and the cranks are interchangeable
and readily available in the junkyard.

Subject: So many requests for info!
I've made about $100 worth of long distance phone calls today on
various subjects that have been discussed here on TM, and decided
to just do one post and let everyone know what I found.
Shims: Select sells TRD shims, which retail for $9.67 each! (swoon!)
I'm not sure what they sell them for, but here is what I can do
on them:
?-2.9mm: $6.15 each
3.0 - 3.25mm: $6.98 each
Stock Toyota shims (just as good, I reckon!) are also expensive, but
not that bad. I can get them for anyone on the list for 10% off retail.
(This goes for anything Toyota sells, btw.) (Steve I: I called JG
and they only do shims for their own head work, as you suspected.)
Throttle Bodies: The TWM throttle bodies are basically just like Bruce
Crawford described. They are designed to bolt up just like a set of
Weber sidedrafts do. They are available in various sizes from 40mm
to 55mm--per bbl! To be pedantic, these are considered 1 throttle body
per two intake runners (according to Keith at AEM), but in either
event it's just like a Weber DCOE: One carb, two bbls, two intake
runners, except now it's one throttle body, two bbls, one injector
per bbl, and one bbl per intake runner. Right now I can sell them for
$246.10 per throttle body (two needed for a 4 cylinder engine.) Doh,
I just realized that I don't know if that includes the injector, but
I'm guessing that it does. BTW, you'll also need a computer to run
these. I really like the description of that setup that Bill told
us about, especially the price. Complete 4 cylinder fuel injection
for just under $1000. That's not bad at all.
Clutches: There are several different clutch manufacturers, including
Centerforce, Japspeed, Ferodo, TRD, Marcel, and others. Since we
were discussing 212mm 4AG clutches:
Centerforce I, CF035542, $308.46
Dual Friction, DF542035, $354.13
TRD Pressure Plate, 550Kg (vs 450Kg stock): $255
Marcel (Ferodo-style) Disc, $140
Japspeed (Metallic) Disc, $150
Some folks like Centerforce, some folks don't. For a performance
clutch, you can't beat the price. Centerforce clutches include both
the pressure plate and disc, so they are priced about $50-$100 less
than the other guys. The TRD pressure plate is "while they last",
since they're not being made anymore. Marcel is a good street/strip
disc, and is basically made out of the same material as a Ferodo
unit. Japspeed is a metallic disc (Dave talked about this one a bit
yesterday), and is also a good street/strip clutch, but probably a
little more strip than street.
Weber rebuild Kits (DCOE): Somebody asked about these and I can't
find their mail at the moment. Dave A? Anyway a real WEBER-made
rebuild kit is $30. You can get a generic-type kit for quite a bit
less, down around $22-$23, but as much work as it is to completely
rebuild a carb, you don't really want to do it twice, do you?
Nobody here on TM has asked about throttle body rework, but I've learned
a little about this that folks may be interested in. You can have a
throttle body reworked (uh, made a bit bigger plus ?) for about $200.
JG (818-281-5326) will do them for about $175, and AEM (310-327-9336)
does them for $225. Call them direct--I really can't get anyone a
better deal than this. If you call AEM, ask for Keith and tell him
that I sent you (I need the brownie points!) On the MR2, I'm assured
that the stock throttle body (4AG) is worth 350hp, so I probably
wouldn't bother spending the bucks on that one. This can be a pretty
big breakthrough on cars that are designed more for economy (like
maybe the Tercel) so it is worth considering. Anybody out there had
this done or able to provide some deeper comments? (BTW, I recommend
AEM--they seem very competent. JG may be good too, but I just don't
know them. Anyone?)

Nowadays, injectors are typically serviced in the car. The mechanic
has a pressure regulator that he attaches to a can of cleaner and
to the fuel line after the fuel filter. The fuel pump is disconnected
(real important if you don't want gasoline shooting all over the place)
and the pressure regulator set to normal fuel pressure (about 30psi.)
The car is started and run until it empties the can. Does a
remarkably good job! Fuel injectors can therefore stay on the car
until there is evidence that they have failed (you'll know) in most
cases.
Before you ask, I don't know where to buy these. Anyone?

I not as knowledgeable on 4AG cranks as I'd like to be, but as far as I
understand it, there are three cranks that are used for NA 4AGE's. The
'weakest' crank is used on the 86 kw big port engine (AE-86 type), the next
best (and most common) is the one from the 88 kw (AE-82, etc), and by far
the strongest is the 100 kw used by the GT Corollas. I have no idea what the
4A-LC or 4A-F uses. (Nor do I care ..... :)
FWIW, the 3A-C is a 1452cc, and shares the same stoke as the 4A series, so
the crank may be the same. There is also a 2A 1295cc, (smaller bore & stoke)
and the original 1A, which I understand shares 1452cc with the 3A.

Doubt it. You can only increase the stoke on a standard type crank by
counter-grinding the crank bearings and using smaller bearing shells. A bit
messy, and you can only change the stroke by a mm or so - not really worth
it. Now, if someone could come up with a supply of 7A-FE cranks it would be
a VERY different story ..... (1762cc, and say a 1mm over bore = 1806 cc, a
more substantial figure)

Can't see why it wouldn't, as I'm fairly sure the only physical differences
in the two blocks is that the Z block has extra ribs on the side - probably
to change to resonant frequency of the block, etc. I am also sure that the
last of the 4-valve 4AGE's ALL had the same ribs on the sides of their
blocks, so perhaps Toyota cut costs by using one block for all engines?

I reckon that you should get them cleaned about every year or so. They
should last the life of the car without any problems that way.
How to tell if they are in need of attention? Hmmm, a bit tricky, but if I
had to guess, I'd say just let the car idle for a while, then (turn the
engine off) pull the plugs out, and if one (or more) injectors aren't
flowing properly then the plug should show a lean condition. (Lighter colour
than the others)
Anyway, it's not that expensive to get them cleaned - here in Aus it's quite
common to have mobile busineses that travel to your house and do it on the
spot for Aus$25 or so each. When they are tested, you can see with your very
own eyes the spray pattern and amount of flow. (They are usually tested and
cleaning in a 'test rig', which is a set of calibrated glass tubes next to a
clock that let you see how much each injector flows in xxx seconds. And the
spray pattern.) The injector dude then usually changes the filter screen
inside the injector body, and that's all there is to it.

swap for a celica and he told me that it maybe doable, but there isn't
room. The engine will probably hit the radiator. Ifyou end up putting
a 7mgte in yoru celica I would be interested as I have an 82 celica with
about 60 hp at the wheel!

Bill,
I do not claim any knowlegde of 4AG crankshafts (or speeling for that
matter ;), however, I am curious because my 85 MR2 has an AW11 engine
code and thought you might know what the other codes might mean.
The 4AG engine has 4 possible engine codes (according to TRD as of '91
catalog - a little out of date...). These being AE82, AE86, AE92 and
AW11. You mentioned the the AE86 and AE82 above and I was wondering what
the other two crankshafts might be rated as, in comparison to the the
other engines in this group.
Oh, also, the 4AGZ (SC engine version from 88-89) shares the AW11 engine
code along with the 4AG.
Just trying to add a little confusion to this already confused discussion.

Subject: Toyota TCCS Vf line meter
Hi all,
I am a contributing member of the Supra Owners Group. With the assistance of
Reg Rimer, President of SONIC (Supra Owners Network in Canada) I have
developed, designed, and am ready to produce a LED display for the Toyota
TCCS computer's Vf line.
I am a 23yr old Electronics Engineer at National Semiconductor, Maine. This
meter is the 2nd generation unit, the first one had a problem lighting up the
RICH led = Vf=0.0v. This new one works great.
After reading the info below, it will be obvious how this meter can protect
your modified Toyota. It is also helpful to diagnose ill stock toyotas.
I am not a business, I am an obsessed Supra owner who uses his skills to make
electronic mods for my car. I have sold 9 1st generation meters to my fellow
Supra owners. I have never seen a meter for this TCCS output for sale, I think
it is unique. Feel free to visit my member page in the Supra Group site:
www.supras.com
I use the slight profit gained from the meters to make other Supra projects,
just by chance this time, almost all Toyotas have this output.
Example: Real Projects in Que:
Human Voice status announcements
Cheap Turbo Timer
Intake Air Temp Meter
Visit my meter page to see this info AND a pic of the enclosure:
http://www.supras.com/m_offer2.html
This meter beats the pants off any Oxygen Sensor meter, be sure of that!

Quick review to to make sure all are up to speed with this little project:
The MKII, MKIII, and the MKIV, have a TCCS output called Vf.
(This line output is described by Reg at the end of this document.)
I have used an application note from a Analog chip here at National
Semi to implement a display meter for the Vf signal.
To install, you will need to:
1: Tap into the Vf signal at the diagnostic box and carry it into the
car for everyday/constant reading.
or
2: You could just tap right at the diag. box for a quick idle check.
Option 1 is much more informative!
About the Vf Meter:
-The device is a almost commercial-quality
printed circut board (no internal wires), with soldered
components, LEDs, and output wire leads.
-The enclosure looks like a slim small beeper.
-The face side is the end, like most beepers have the readout.
-The dimensions of the enclousure are: 2.2" x 2.8" x 0.71" .
-The material of the box is textured plastic.
-A tail of 3 wires come out the bottom of the enclousure: 12V, GND, Vf.
-The supply voltage can be 3v to 35v, no kidding!
-The display face is clear, the LEDs shine thru the window.
-The display is five colored leds.
Only one led is illuminated at a time.
The led array is: r-y-g-y-r colors. The definition of the LEDS is
given by Reg in two notes at the bottom of the letter.
-There is a green *on* light.
*-Can be used by other cool Toyota and Lexus vehicles with a Vf line.
I have made 9 first run meters so far. They all have been sold to 6
supra group members. This ended up being a Beta test it seems,
I came up with a few fixes.
This is NOT a business, just a project by myself, another obsessed Supra
owner.
Price: US$ 50. in enclosure
40. without enclosure

You may want to look into using the Vf output from the diagnostic block. It
outputs 5 stepped voltages up to 5 volts, telling you what the TCCS thinks
the system is doing.
-* spec *- -* most cars *-
0.00 volts = Rich 0.0v
1.25 volts = Good 1.1v
2.50 volts = Best 2.19v
3.75 volts = Good 3.5v
5.00 volts = Lean 5.0v
The voltage may not exactly represent the figures above, according to my
TCCS Tech books. The point is that there are 5 steps to the system. My car
always runs in the good to best areas on the rich side. I have seen it go
to lean with cold startup and while decelerating with foot still on gas
pedal. This system is telling you what the TCCS fuel trim system thinks the
system is doing based on all measured conditions, not only on the O2 sensor
reading. The fuel trim system has a number of factors governing its
operation. The TCCS uses a look-up database in its memory to cross
reference its measured information with what the current data is. This is
why the idle speed on the 7M-GTE always moves around from time to time. IE:
air on, lights on, car moving, etc. It is normal for the GTE engine to idle
at about 1200 rpm when rolling into an intersection, then when at the
light, resting to ~700rpm.

-* Additional note from Reg *-
The Vf output has three different types of Vf output.
*OXYGEN SENSOR FEEDBACK MODE
*DIAGNOSTIC MODE
*LEARNED VALUE MODE
See below for details:
_____________
#1
Oxygen Sensor Feedback Mode.
*T1 and E1 Connected
*Idle contact point off
*Engine at 2500 rpm
Result of Ox sensor signal processing
5v.......Rich
or
0v........Lean
0v...........Open loop condition
_______________
#2
Diagnostic Mode
*T and E1 connected
*Idle contact point On
*Engine off
Results of Diagnosis
5v........Normal
0v........TCCS Trouble code stored, check 'Engin Light'.
________________
#3
Learned Value Mode
*T and E1 not connected
*Any Speed
Result of Air-Fuel ratio voltage feedback
0v...........Rich *red*
1.25v.........Normal *yellow*
2.5v...............Normal *green*
3.75v.........Normal *yellow*
5v...... ...Lean *red*
On Light= another *Green* LED
Learned Value:
It is a fuel injection correction coefficient which tailors the standard
fuel injection duration to minor differences between engines due to
manufacturing tolerances, wear, and minor mixtures disturbances like small
vacuum leaks.
This coefficient is capable of altering the calculated injection {before Ox
correction} by as much as 20% to prevent Ox sensor correction from being
excessive.
If you encounter a driveability problem that sets no codes, this Vf voltage
feedback can be of some help. Especially code 25/26. {engine condition rich
or lean}
Note:
*Discard Vf reading when engine is cold.
*The Vf learned value tells you how hard the ECU is working to keep the
engine running properly.
*After loss of power to ECM, it will take a certain amount of time to
relearn, depending on the engine model and vehicle driving conditions.
*The ECM will learn faster if the input signals are stable
*At high altitude operation, Vf can be 0v but it is considered to be normal
{lack of oxygen}
*Vf voltage reading may be different, depending on accuracy of voltmeter,
and connections. However, the number of steps 5 are still the same. {e.g.
1.10v instead of 1.25, 2.2v instead of 2.5v, 3.5v instead of 3.75v}
*Vf voltage can be "border line" also, flipping back and forth between 2 ranges.

Cc: toyota-mods@cyberspace.cyberauto.com
Hi Bill,
With reference to your last message in which you said
that increasing the stroke of a motor would increase the torque but
not the hp and could result in a loss of hp, I have an example of a
factory stroking a motor and claiming an increase in both hp and
torque, namely the L24 and L26 as used in the 240Z and 260Z.
The bore is the same at 83mm with the stroke on the 240 being
73.7mm and that on the 260 being 79mm. The height is the same at
265.9mm.
240Z 260Z
BHP 151@5600 165@5600
Torque 146@4400 157@4400
So from the specifications it appears that the factory stroked
the L24 motor 5.3mm and called it the L26 and claimed an increase in
both hp and torque.

actually these codes refer to the car (as far as i know this system works
up to the very new cars and possibly some trucks) the first letter refers
to the engine block e.g. if the first letter is an 'A' then the engine is
an 'A'-series engine such as a 4AG, 3AC etc, if it is a 'T' it is a 'T'
series engine e.g. 2TG 2TC 3TGTE, etc. the second letter is the model of
the car e.g. 'P' is a starlet, 'E' is a corolla, 'A' is for celicas and
carinas, 'W' is for mr2. the last two numbers refer to the specific car
with higher numbers meaning newer as in a KE27 is an older car than an
AE86 but this does not translate from model to model as in you can't tell
just by the numbers if a AW11 is older than an KE27.

Yup, for an average RWD car you could use 25%-30% loss. For a FWD, I think
25% would be about right, and a 4WD up around 30%-35% I'd reckon.
FWIW, the most efficient would probably be a Top-Fuel drag car - they have
no gearbox, only a computer controlled six-stage clutch and a live axle diff
- 10%-15%?? (neglecting tyre drag)

Hey there!
Three things that effects in clutch - plate pressure, diameter and
the number of clutch plates.
In this case u lose more than gain! If u use small copper plates on
your clutch plate then u have higher pressure (force/pressure area),
but remmeber to keep the original diameter or u won't gain as much
torque handling as u could!
In F1 cars they use wery smaal diameter clutch to get the weight
point lower. Becouse they don't have high diameters they have to
use multiple disk systems - they use 6 to 10 clutch plates on that
to get more torque handling.

I'll let Dave answer that, but the smaller surface area will give more
pressure against the flywheel. Pressure=force/surface area.

PPS. The best suspension u get if u go the way of rally cars! Find a
shop that makes your suspension adjustable (like in rally and track
cars) and use then two small springs - diameter usually about ~8cm.
Use soft and stiff spring in compination to get the best ever ride

A VW Beetle gearbox is closer to the action of a FWD than a traditional RWD,
but the differential is driven less efficiently. The only RWD part they are
missing is the tailshaft, so they'd pick a small (a percent or so?) amount
of efficiency that way. (compared to RWD)
In Aus, (and England) we have a 2-litre Touring car series - the top
contenders are BMW, Audi, and to a lesser extent Ford (Mondeo, a Mazda V-6
clone). The fastest car in a straight line is the BMW (Ford not far behind),
and the Audi losing out some at terminal velocity. I believe the Audi to
possibly be a better engine for two reasons - 1. The cylinder size is closer
to the optimum 4-stroke size of 400cc, and 2. 5 cylinders might be better
for torque. (but lose out on friction) Disregarding all other factors
(aerodynamics, tyres, etc), this means that the Audi has greater
transmission drag than the other cars, but as it has a 4WD gearbox, this is
not surprising. (It'll also pull up better than any of the other cars
because it can use engine braking to far geater effect) Ok, how much does it
lose? If we can use the figures of 13%-15.5% for the VW's, then there is not
much chance that the Audi can be better than that with a 4WD box, is there?
(Yes, the rally gearboxes are more efficient than what the public get, but
effectively 50%? Hmmm, possible, but not likely.)
The Volvo. I agree that a FWD gearbox is more efficient than a RWD, but I am
still dubious of the relationship of the figures. I'll explain why.
I have seen many reports of chassis dyno's being somewhat less than
accurate. I believe the only accuate chassis dyno available is the one that
sits in your own workshop. (if any) Not using this as an excuse, but too
many times I have heard of customers being enticed back to the same dyno
shop with the promise of extracting more power. This is of course done for
finacial reasons - on the part of the owner of the dymno shop. If you go to
a shop because they are getting results in increasing power for you, then of
course you'll go back there. The owner of the shop, if unscrupulous enough,
will change the loading on the dyno to make it appear as if your engine is
producing more power than what it is - believe me, it is laughably easy to
do this and stay undetected. As an example, a friend of mine recently had
his sports car dynoed at 155 hp, when in fact a car that was dynoed at
another place at 125 hp can outrun the first car easily! In other word, I
take the figures from a chassis dyno with the proverbial 'grain of salt'.
Good for impressing the kids. I DO believe, however, that they are good for
making comparisons when you alter spark timing, cam timing etc - not
ultimate figures.
Engine dynos are far more accurate, but can also lead to artificial power
figures, eg, when Australia was running Group A Touring Cars, a number of
teams had Ford Sierra Cosworth Turbo's - On an engine dyno they can produce
a genuine 600 hp, but (mainly for cooling restrictions) in the car they were
down to only 550hp - an 8.5% loss.
Another consideration is enviromental - the colder the air, the more power
the engine puts out. A rough rule of thumb is for 1 deg C, power goes up 1%.
If there was a 5 deg difference when the figures were taken, (chassis vs
engine dyno) then that could be a factor.
The engine figures aren't qualified - are they SAE, DIN, or BHP? Big
differences - I think that SAE is hp at the flywheel with the engine having
no waterpump, fan, alternater, etc. So if the Manufacturer uses SAE, then
you are being fooled. DIN is (I think) with all ancilliaries fitted.
Technically, BHP is the measure of hp AT the driven wheels, ie, HorsePower
applied to the (dyno) Brake.
How about tyre pressure? By bumping your tyres from 28 psi to 38 psi, you
can increase your fuel economy noticably - it's all part of % loss.

Ok, all that being said, I'm quite happy to compromise and take about 5% off
all my figures. If Timo could get some more comprehensive details as to how
all those figures were obtained, then we could get some more accurate data
on % loss in transmissions. I'll call a RWD 20% - 25%, FWD 15% - 20%, and a
4WD 25% - 30%.

I have early '88 model of FWD AE92 FX Gti Corolla. I have installed
4A-GZE pistons and almost installed the connection rods too, but the
rods were as far as I could figure the same (!?) - piston pin hole & bearing
size. Anyway the cylinder block had the same bearing journals than
4A-GZE (bigger than early 4A-GE models). Also the block seems to be
different from RWD engines. I think Toyota changed to bigger bearings
in the 88's (some really early AE92 4A-GE engines have for somereason
small bearing journals!)

Bill,
I do not claim any knowlegde of 4AG crankshafts (or speeling for that
matter ;), however, I am curious because my 85 MR2 has an AW11 engine
code and thought you might know what the other codes might mean.
The 4AG engine has 4 possible engine codes (according to TRD as of '91
catalog - a little out of date...). These being AE82, AE86, AE92 and
AW11. You mentioned the the AE86 and AE82 above and I was wondering what
the other two crankshafts might be rated as, in comparison to the the
other engines in this group.
Oh, also, the 4AGZ (SC engine version from 88-89) shares the AW11 engine
code along with the 4AG.
Just trying to add a little confusion to this already confused discussion.

The width of AVS and 8000 are identical. I got very detailed info on
both tires before getting my 8000s!! Overall and ground contact
specs are equal when measured on the same size rim.
On the Yoko spec chart it is VERY EASY to misinterpret data as I
initially thought there was a difference too. There is not.
Make sure you are comparing:
-- INFLATED AND LOADED measurements
-- Same size rims used in both measurements
-- Compare ground contact patch width on 8000 to
ground contact patch width on AVS...They're equal
-- Compare overall tire width on AVS to
overall tire width on 8000.................They're equal
Don't compare overall width on one to footprint on the other-- they
are not the same measurement.
Note that the D40s ARE WIDER than either the AVS or 8000 in any given
tire size!! Go to Dunlop's web page and check out their tire library (think I
recall the address was http://www.dunlop.com) It will illustrate
some of these sims/difs.
I like my 8000s-- especially in the South Florida rain, but I often
feel that I could really push out of curves (dry weather) much harder
with other tires.
The only gripe I have with the 8000s is that when I go from a full
stop into a fastly accelerating left or right turn (ie. left turn
lane) the subjective feel is that the tires lose grip way before
they should. I almost always find myself easing off the throttle
because it feels like tire-spin-fishtail time. Yes, I have LSD. I
don't recall this sensation from the cheaper house brand V rated
tires that were on the car when I first got it. They probably had a
wider footprint at the expense of sidewall rigidity. Whatever.
Umm, nevermind,-- I'm probably just another obsessive-compulsive

My 85 MR2 still has the original factory muffler. (90k miles)
However, you might want to move to a stainless steel muffler (like
borla or other such high performance mufflers) They often have very
good warranties with the added benefit of more power. Although, if
your mufflers are under warranty, I wouldnt complain, just get

Subject: 4AG CAMS
To the list,
Chris's package arrived in Australia and as promised the HKS flywheel and
thin head gaskets are really nice stuff. Stay tuned next week as I'm putting
this wheel in my 1985 4AG with its metal disk clutch and standard plate.
The cams are 270's but they are the type that achieves the duration by
grinding the base circle away. This means large shims. On the 2TG the
large shims were trouble. They cracked and resulted in zero bucket to
cam clearance. The cams ground the bucket away and the motor was history
with all that metal in the oil system. But the 4AG has a much larger shim
and if hardened properly this type of grind may work ok, the trick is to
get a very hard shim of the correct thickness. I will measure the shim
thickness and see if I can get them locally. In short my 2TG ran a 280
grind in the base circle manner, if the shims are correct the motor WILL
run just as well as a welded cam. For those of you that have written to me,
these CAMS are not HKS quality, as you just drop an HKS in and go, they use
standard base circles but with a supply of good quality shims,small grinds of
260 to 280 should work ok. It may well be usefull for Chris to append the HKS
setup instructions as, these detail the all important 'G' value and overlap.

The car is running out of steam. The aerodynamics, friction losses, rolling
resistance, ETC finally was too great for the engine to overcome. a lot of cars
go 'faster' in 4th than in 5th or 6th. usually the engine can't overcome the
load put on it by shifting to a higher gear. (Less mechanical advantage) also
you might be in the 'peak powerband' at that speed, and shifting to 5th moves
you outside the peak, thus not only did you decrease the engine's mech.
advantage, but you just put it in a RPM range where it's not making as much
power.
in short it sounds like it's time to add some more power.

My 1988 n/a has eaten one muffler since I bought it at the start of last
year, and checks of the past maintainance records say that it has already
been replaced once in 1991, and this is ising "genuine" toyota parts.
Not sure exactly what is going on here, any of you guys have any comments
on either the quality of Toyota mufflers or the MR2's abilities to eat
them with such gusto? In Australia they cost a firtune (and I presume in
other countries too).

Subject: Re: Tire Width (AVS vs 8000)
Doh! I'm not going to get a copy of this, but I couldn't resist
just a quickie note. Everybody remember that the width of a tire
is completely IRRELEVANT to the tire patch size--it just affects
its shape. Take a 185/80 and a 255/60 and put 30psi in both
tires. Now, put one on the car, measure the contact patch, then
do the same with the other tire. The patch will be the same!
(Tread will affect this some, but let's say that the tread pattern
is about the same.)
Why a wider tire then? A couple of good reasons. Probably the
best one is that a tire with more surface area is better able to
dissapate heat and will wear less per revolution. Is handling
any better? Maybe, maybe not. Handling improves as the height of
the tire shrinks. Further comments?
There are a series of absolutely excellent articles on the British
Car web site that explain this and more. I'd give the address,
but I'm too lazy to fire up the web browser at the moment and
look. I'm 90% sure that I put a link to this info from the TM
web site way back when, so start looking there (Maybe going there
will inspire someone to do some web page work for the woefully
neglected site!) www.cyberauto.com/toyota-mods

Hi Ade,
I would really appreciate the details of the E-brake cable
replacement. When I first bought the car, the brake cables were frozen and
needed replacement which cost about $400 by a local repair shop. I do about
80% of my repairs myself now, but I've been a little reluctant of the idea
of replacing these cables. My car has been garaged for the winter and I've
been avoiding setting the E-brake as much as possible in hopes to avoid
having it freeze on me. But I know it will probably happen again within the
next few years, so it would be a great help to know how to replace them in
detail.
Thanks :)
