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.

Subject: exhaust on an 88 camry
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.

Thanks...I'm putting in springs and strut cartidges next week. Maybe you

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.
