Graves) Subject: Re: 88 Corolla GTS mods To: fredo%majikthise@ert.sp.paramax.com I have a 1988 torbo altrac celica and have been very frustraded at making improvements to the oil system. I'd like to improve the handling but have not had much luck in locating anyone in the San Francisco Bay area that deals with such things. This list(toyota@quack.kfu.com) doesn't seem to carry much, I think theres one other altrac owner out there, but have heard nothing about performance mentioned other then a question about cpu chips. I'd like to be involved with a discussion about improvements in both performance and reliablity. I have 80k miles on my altrac and replaced the engine at 64k.

Also, a couple of friends, acquintances, and I have have modified the predecessor engines (2TC, 2TG, 3TC) and I have a few numbers to call for performance parts. We have also modified a few Celica en- gines (18RG, 20R, 22RE). We have also retrofitted various engines in different cars. But, we have never FULLY modified a fwd car before; I presently have an '87 Integra that I installed a perfor- mance exhaust on (Walker Dynomax with 2 1/4" pipes back from the cat.), stiffer (performance) shocks, and plan to install headers. I may change the chip to a AutoThority chip and the cams (maybe Jackson Racing). My brother has an '84 GTS, same engine but rear wheel drive, that he plans to modify soon. He just started working a REAL job; this is his first job since graduating from undergrad (last year). So, he's still saving for this new project. Thus, the information that you gather for the engine modifications will help him. Thanks for any information and I will give you any info that you need (or request). -Errol. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Errol Young ~ Internet: egy@cc.bellcore.com ~ ~ Bell Communications Research, Inc. ~ -or- eyoung1@cosmos.bellcore.com ~ ~ 444 Hoes Lane, RRC 4D-531 ~ ~ ~ Piscataway, NJ 08854 ~ ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx From: ert!dip1.ee.uct.ac.za!Greg Date: Mon, 19 Jul 93 21:41:17+020 To: fredo%majikthise@ert.sp.paramax.com Subject: Re: 88 Corolla GTS mods Hi Fred, > > I own a 1988 Corolla GTS (4AGE engine) which I am in the process of modifying. > These mods include some "professional" and some "amateur" performance and > handling mods.

The engine has the variable induction system (TVIS) that boosts torque at low revs. It has 89kW peak power and +- 141Nm peak torque. I don't know if this is identical to your engine. Anyway, Toyota SA dropped the TVIS (apparently due to cost) but tweaked the engine to improve performance. 1990+ models have 97kW and 145Nm. Torque only suffered a little at very low revs. If I remember correctly, what they did was increase the compression ratio and add a knock sensor, and improve the EFI. The newer cars do a better 0-100 and have a top speed of +-200 km/h, roughly 10 km/h faster than my car. Reliability is still first rate. If you would like more detail, I could find an article I have buried somewhere. Alpine SA also offers a turbo and suspension upgrade. 130 kW of power :), but very thirsty. > I am somewhat uncertain if direct email is more appropriate for this subject > so I would appreciate some advice from more experienced users of this mail > service! > The lack of traffic I see on this list indicates to me that email is the way to go, with a summary of the posts you receive going to the list later.

I have a 1983 toyota starlet with a 4AGE engine that's fitted with TRD components. While I did not do the modifications myself, my mechanic who is a very good friend "allows" me to help out whenever I can. I therefore have some first hand experience on what's involved in modifying the 4AGE.

You now own the same model of car that I was gonna get before I found the one I'm driving now. I have an '88 Corolla 4dr. I would be very interrested in hearing about all of the mods that you do to your car. I've noticed that mine seems VERY quick and responsive as compared to similar, other-company's cars. I actually beat a M*st*ng 6cyl. off the line! I've been thinking of taking it down to the local 1/4 mile strip, just to see exactly how fast it is. What kind of exhaust will you be running? Stock, or are you gonna get some larger pipes? What else are you gonna change? Waiting for the news, Derek Janzen angman@sfu.ca ps. I think that you might want to keep this one on a more personal basis. You could create an alias (do you know how to do this?) and have the names of all the people who are interrested in this topic listed under that alias. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Date: Tue, 20 Jul 93 09:36:35 CDT From: fredo (Fred Oberbuchner) To: ert!WRGraves@Riem.Com, ert!egy@cc.bellcore.com, ert!Greg@dip1.ee.uct.ac.za, ert!roger@sickkids.on.ca, ert!angman@sfu.ca Subject: "88 corolla gts" group Cc: fredo Well, it appears that some curiousity was aroused by my "88 corolla gts" posting (glad to hear from you all). What I have decided to do (suggestions welcome) is to leave this as a semi-private group for which I will volunteer to be the "mail server". Every once in a while I will send info out to the "Toyota" mailer where I originally posted to see if any new interest is aroused. What I would propose we do (so far there are 6 of us) is to write up a basic introduction of who we are, what we have (are interested in or just curious) and what our intended application would/could be. I do not consider myself a G*O*D* so any criticisms or suggestions are welcome! (there, that's my disclaimer!) Well, 'nuff said, here goes..... ME: Fred Oberbuchner Winnipeg, Manitoba, Canada fredo%majikthise@ert.sp.paramax.com MINE: 1988 Corolla GTS 4AGE engine 1.6 liter fuel injected twin cam 16 valve TVIS (Toyota Variable Intake System ?) rated 114 horsepower (what is the conversion to kW anyway?) MODS: so far I have only done (read: been able to spend money to do) the following mods: HKS Max-Flow Sport Exhaust System HKS Street Cams K&N cylindrical air filter (delete stock airbox) MSD-3 (3?) Multi-Spark ignition system Springs (front&rear) - Suspension Techniques All of the above mods with the exception of the MSD were performed by Jackson Autosport here in Winnipeg. (note: I am an electrical engineer and definately not a mechanic so I leave this stuff to the people who know!) IDEAS: 1. I've tried playing around with the RPM at which the TVIS opens the extra 4 intakes but don't have accurate data as to the difference this makes (I need to hook up my computer and log some data, which I haven't done yet) 2. It has been suggested to me that opening the cold-start injector at higher rpm may help as I do have the more radical cams (any experiences?) 3. I have heard that Japan has/had a Corolla GTZ which is a supercharged version of the 4AG (known as the 4AGZ). If anyone has any info on this model I would love to get my hands on it! 4. I have always wanted to super/turbo-charge my Corolla, however, this seems prohibitively expensive as it would also include a new computer, etc, etc. 5. Going to 15 inch tires also seems interesting COMMENTS: Anything else I have forgotten to say. Well, that's all for now. If everyone sends mail to me I will relay it to the entire group (or would it be better for me to just provide all email addresses for everyone? - feel free to object/agree if you so choose) regards, fred. fredo%majikthise@ert.sp.paramax.com xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Date: Tue, 20 Jul 93 09:15:38 PDT From: ert!Riem.Com!wg (Wayne R.

Graves Orinda, California, USA WRGraves@Riem.Com MINE: 1988 Celica Turbo Altrac, 200hp, 80k miles 1986 Celica GTS, 130hp, 140k miles Both stock MODS: none on the engine yet. Using red line 20-50 sythectic oil in the altrac. Both cars have had engines replaced, the altrac at 64k miles and the GTS at 102k miles. Have put alarms in both cars and a pioneer 6-cd changer in the GTS. Have replaced just about everything that moves on the GTS. INTERESTS: Improve gas mileage/performace,reliability and suspension. IDEAS: 1.Increase the size of the oil system and use SYSTEM-1 oil filter on the altrac. Turbo's eat oil bad, even sythectic. Dirt and temperature are major problems that should be fixable. Oxidation is a major problem but I don't know what can be done for it. I have looked around and found hardware to increase the capacity of the oil system but have not been able to find anyone that would install it. I plan to attempt to install it myself later this year. 2. Improve the suspension. It seem very mushy for as much power as these cars have. 3. Add sensors and gauges for oil temperture, I find the altrac runs very hot and the water temperture gauge does not give an acurate picture of whats going on in the engine compartment. COMMENTS: I've been driving toyotas for 18 years and it looks to me like the newer they are the poorer the reliablity and the poorer the quality. My 78 was lots more reliable then either my 86 or my 88.

If anyone has any info > on this model I would love to get my hands on it! As I mentioned, I turned down a 4AGEZ which came from a (85-87?) supercharged MR2. The guys at FACES had this engine in a 1985 RWD corolla GTS. It had CAMS, bigger injectors, bigger supercharger pulley (all from TRD) ... and it was very fast, or so they thought, until another performance shop nearby put together a turbo charged supra. In any event they took the engine out and shipped it down To Barbados where it is now in a Starlet that is set up strictly for circuit racing. From what I recall my mechanic said, the 4AGEZ will fit in the RWD corolla GTS without any mods. I'm not sure how you would adapt it for a FWD 88 corolla as the engine has more stuff in the way of pulleys and electronics hanging off of it, and as such might be too wide to fit transversly in the 88 corolla. (the 88 is front wheel drive isn't it?) In the 85 corolla they have.. a 3T-GTE engine (estimated around 275 BHP), That was imported form Japan. It is the same base engine that is used in the 99 Toyota GTP car. -- 2000 Twin Cam, Twin Spark, Turbo charged. > 4. I have always wanted to super/turbo-charge my Corolla, however, this > seems prohibitively expensive as it would also include a new > computer, etc, etc. I recently met a Mechanic here in Toronto who put a Turbo kit (from HKS) onto a supercharged MR2. (The owner of the MR2 has some affiliation with Toyota!!). While I have not seen the car as yet. It is supposed to have done an *official 12 second 1/4 mile. (official in that it was electronically measured) The cost of the kit was about $6000 CDN. It was strictly from a cost perspective that the guys at Faces switched engines. The cost of the 3T-GTE with factory turbo, was more appealing than an HKS turbo kit. Anyone know the name of the Japan only Toyota car this engine came out of? > 5. Going to 15 inch tyres also seems interesting What is your current tyre size. The 85 corolla above is running 205x50x15 tyres, since it is lowered, the side walls rub a bit. From what I understand, they needed to "beat" the lower lip of the fenders up, as well as "pull" the fenders out a little bit so the wheels would fit within the fenders. I thought of stepping up to 15" tyres for my starlet, but 205x50x15 wouldn't fit. (Some cars are designed with generous wheel wells, unfortunately the starlet was never one of them). Tyre size, and profiles is something I have been looking at for the last couple of months. I thought of going to 195x45x15, but since my car is barely streetable as is, I didn't need the added harshesness of low profile tyres. Also with low profile tyres if you drop into a pot hole you risk damage to the rims. I am hoping to get a set of 14" rims and tyres to use on long highway trips as my 4.1 diff coupled to 13 inch tyres makes for very "buzzy" (re: high RPM) highway driving.

(roger) As a computer programmer, I'm not a fan for debugging code written by other people. Let's say you can disassemble the prom , all you will see is a bunch of hex numbers, The meaning of which only the designers know. I don't want to discourage you, It probably can be done with time. Some of the chips you see for sale are probably engineered this way. HOWEVER I recall an article in an english car mag where a cosworth engine was destroyed due to a bogus chip upgrade (detonation occured). >I heard that sport PROMS are not available for Japanese cars because they >solder the PROM - does anyone know of a place that DOES supply PROMS? > Reading through the HKS catalog I am left to believe even HKS with all their upgrades don't touch the proms in the factory computer. They provide their own "computer" that plugs into the existing ECU and controls only the HKS components. Depending on the route (re:money) you could change to a haltech or electromotive programmable EFI both have an interface and optional software for a pc (sorry no macintosh stuff is available) that allows you to program the fuel curve. It is a 64 point table that has engine rpm on one side and I think injector time on the other. The unit does interpolation for the rest of the rpm range. List price is the biter though. >Just out of curiousity... ROGER... what was the cost of that 4AGEZ? (and when) I'm not sure (someone correct me here) but the EFI in the corolla is a closed loop system, therefore if you do stuff to increase fuel in the cyclinder and the exhaust sensor detects anything other than what it was programmed for (at a particular throttle position), it might do something weird to the spark advance, and actually reduce power(just my $.02) I think they ended up selling the 4AGEZ for $1500 US > -- Roger Smith | Research Computing Services, Software Development | The Hospital for Sick Children, Internet:roger@sickkids.on.ca | Toronto, Canada.

The corolla EFI does have 1 injector per cylinder, however, it also has (as does the 22RE engine in my truck) a single injector in the intake manifold which, on cold mornings is opened fully when the key is turned to the start position thereby putting more fuel into the cylinders. (I also have the pair of shop manuals for my car) My mechanic's off-the-cuff idea is that by opening this injector at high rpm one could very cheaply increase the amount of fuel entering the cylinders and thereby richen the mixture (which should give more power as I do have the cams and exhaust in place to support this). I am going to try and test this by connecting the injector to the same control which opens the 4 secondary intake ports in the TVIS at about 4500 rpm. If this works, it would mean simple re-wiring only (cheap or what!) and maybe the addition of a relay. Unfortunately, I am also battling this time problem so this may take me another 4 weeks or so to get to this! Also, has anyone heard anything about simply replacing the stock injectors with injectors with a higher flow rate? fred (fredo%majikthise@ert.sp.paramax.com) xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Date: Thu, 22 Jul 93 11:07:38 CDT From: fredo (Fred Oberbuchner) To: fredo, ert!WRGraves@Riem.Com, ert!egy@cc.bellcore.com, ert!Greg@dip1.ee.uct.ac.za, ert!roger@sickkids.on.ca, ert!miller@dg-rtp.dg.com Subject: Re: 4AGE engine mods > I have an '89 MR2, which I believe has the 4AGE engine.

Also, > are there any negative effects of doing this? At the time when I changed to a thinner head gasket, I took the opportunity to have the "valves" redone. (i.e clearances checked/set, new valve seats cut, grind valves, etc) Once timing was sorted out, there was a noticable increase in bottom end torque. However this is probably due to the combination of gasket and valve work done. There is a formula for calculating engine compression ratio that takes into account gasket thickness (don't recall what it is). Each point increase in compression ratio should translate into more torque. I haven't heard/experienced any negative effects with my mods. Have you tried playing around with the cam timing?

Any opinions? > I have had some experiences with headers and truly think that they make a difference (increase) bottom. My friend had a '76/77 323 GLC that he changed the exhaust mani- fold to a headers (1.3L engine, ~50+ hp). I had an 80 SR5 without headers (3TC 1.8L, ~70+HP). Before he had put on the headers, I used to outrun his car - from the line and top end. After he put on the headers, I could not catch him. Thus, from this experience, I infer that the headers make a significant difference - although, this is just an instance of the whole - this may not be the same for your case. My other experiences are somewhat different... the other cars that I know, and have driven or driven into with headers, were modified. So, I cannot make a judgement on these experiences because I never drove, or drove in, these cars with the OEM exhaust manifold. How about asking Roger about this? BTW, I have driven in an 84 GTS with headers (and other modifications - cams, port and polished head, dual 44mm Mikunis, full Tokico suspension [springs and 5-way shocks], etc) and it was extremely quick and handled like a dream! -Errol. ----- End Included Message ----- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Date: Tue, 27 Jul 93 15:11:07 CDT From: fredo (Fred Oberbuchner) To: toyota-mods Subject: toyota-mods submissions NOTICE TO ALL SUBSRCRIBERS: When submitting mail to this list please send stuff to: toyota-mods%majikthise@ert.sp.paramax.com and not to me directly!

One big advantage of the TRD header is the manner in which the exhaust pipes come together i.e 4 seperate pipes all the way until it joins the catalytic converter ;-) vs The stock exhaust manifold which goes into one pipe right off the block, also the way the pipes are "bent" play a role. (if you can visualise what I am getting at). A simpe trick I have seen done (and suggested in the toyota performance handbook as adding 2-3 HP) is to wrap the header with some thermal insulating tape.

I'm not real familiar with the 2WD trucks, but I believe the torsion bars are adjustable. On the '86-present 4WD trucks, the front suspension uses torsion bars, and I've heard that these can be "cranked up" about an inch as a cheap lift. So I'd bet that you can easily "crank down" a 2WD's torsion bars. Before doing this though, figure out how much upward wheel travel you currently have, 'cause if you take away too much, you'll be bottoming out a lot. Torsion bars are usually adjustable at the rear-most end of each bar, where they attach to the frame. -BruceR -------------------------------------------------------------------------- Bruce Rioux Internet: brucer@hw.stratus.com Stratus Computer, Inc.

I think the TRD kit for the conversion (including Mikunis) is close to $1400 US. Carbs are still predominant in racing circles due to costs as well as ease in tuning for a particular race environment. I read an article recently in the english magazine "car and car conversions" where they compared an aftermarket performance EFI (Lumitron?)to twin carbs (webers). (Both on the same engine) The end result was that the EFI produced about 12 BHP more but only at the top end. For most of the rpm range the carbs performed better.

I had a Doug Thorley header on a 2.4L I4 Nissan engine and the lifetime warranty would be void if any type of wrap was put on them. It seems that while keeping in the head does increase flow it also shortens the life. Something to think about if you want your header to last and the warranty to be good.

From the advertisement, I infer that you have to send the headers (or any other exhaust pipes) to them and they'll "prepare" it for you.

With the header wrapped in thermal tape (A brand name of Thermo-Tec springs to mind) you are supposed to be able to grab hold of the exhaust (on a running engine) with your bare hand and not get burnt. I would hesitate a bit before putting my hand on a header that was "merely" painted with some coating. Isn't Jet Hot applied with a brush? The TRD header on my 4age is advertised in the catalog as having a hi heat thermal coating. I recall one of the guys at FACES having said that after a short period, the header lost its "blueish" colour. -- Roger Smith | Research Computing Services, Software Development | The Hospital for Sick Children, Internet:roger@sickkids.on.ca | Toronto, Canada.

It does not have as much techical detail as I remembered, but I have transcribed the interesting bits. I will let you judge whether it should be sent to the group. "Toyota claims to be the largest manufacturer of multivalve engines in the world which, considering its huge production volumes and pioneering work in putting multivalve engines into bread-and-butter cars, is easy to believe. In the case of the 4AGE motor the TVIS broke fresh ground in overcoming one of the main disadvantages of 16-valve engines - poor inlet gas velocity at low engine speeds, which leads to a drop in torque." "TVIS achieved this using two inlet tracts per cylinder, with a butterfly valve to close off every second tract at low engine speeds, thus raising inlet gas velocity in the free tracts. The result was a remarkably good spread of torque for this type of engine." "Expense was quoted as the main reason for droppping the TVIS in the first quarter of 1990 but Toyota South Africa was quick to point out that the revised engine developed 8 % more power, along with 3 % more torque (89kW @ 6600 rpm to 96kW @ 7000 rpm, 141 Nm @ 5000 rpm to 145 Nm @ 6000 rpm). The main factor behind the increase was a lift in the compression ratio from 9.4:1 to 10.3:1, which in turn called for some other tweaks." "KNOCK SENSOR ADDED" "Chief among them was the addition of a knock sensor to the existing EFI and ignition setup to prevent detonation problems. Cylinder head design was also revised, as were the inlet and exhaust manifolds." "The character of the engine remained unchanged apart from a feeling of slightly slower throttle response and a little less urge at low engine speeds. From there on up, however, the new 4A-GE engine was all go, with tremendous range and smoothness. Its probably the sweetest running engine in the class." There... thats all I'm afraid. In fact I now recall a more detailed description of the mechanicals in the review of the Conquest (hatchback 4A-GE). Unfortunately I do not have this issue (read it in a doctor's waiting room). BTW, what is the pricing of the Corolla range over there, and what models are available? Later...
