5M-GE Modifications Guide

[quick]

It strikes me that it would be beneficial for a modifications list (like on MkIV.com), so let's work one up. I'll start it off and others can reply with additional suggestions.

I'll edit and prune this all down once a week or so and we should have a definitive 5M-GE bolt-on modifications guide.

Basic performance mods:
1. Air filter: Either a K&N-style cone filter, a modified airbox, or a ram-air style intake. (links needed)
- RabidChimp OpenElement air filter

2. Intake pipe: Dyno numbers from RabidChimp.com have indicated that there is a decent horsepower gain with the use of an intake pipe. This can be built or purchased. (links needed)
- RabidChimp Mandel-bent Intake

3. Cat-back exhaust: (writeup and links needed)
- Brullen (contact information needed)

Advanced performance mods:
1. Header: Doug Thorley, Pacesetter. (writeup and links needed)

2. AFM Mod: (writeup and links needed)

3. Bored-out throttle body: (writeup and links needed)

4. 5M-GTE: http://www.supraforums.com/showthrea...threadid=50161

ok, I have the turbo and I'll post exactly what i did to make it work as it comes along. I've seen some sites on this (aka http://geocities.com/aarongarney/5mgte.html) but most of them don't have a good step by step guide. So from now on in, I will post my findings in the forums. ICQ availible, post SUPRAS as a subject for authorization. 144749945.

[85supra]

Hi, this is my first time. If it is by anyway sound stupid, please just bare with me.
I just got an 85 supra and I have a problem with it. When I first got it, the car only started and wont take gas. Now that I fixed it, it only slowly accelerate to 2500 rmp then drop. After running for about 10 minutes I saw the exhuast side the camshafthousing (not the exhaust maniford itself) gasket starting to blow bubles and wetness on the side.
PLEASE HELP!!!

[SupraWes]

You need new cam housing gaskets. Luckilly fel-pro makes them so any parts store that sells fel-pro gaskets can get them for you. The job takes about 2 hours and requires the removal of both timing gears and the rear timing cover so make sure you have the engine a TDC before beginning as it will be real easy to put things back together afterwards.

[supraII]

I did that already, but not sure if I got the timing set right or not.
I set the crank to 10 TDC, both cams at the marks and the distrubitor with the rotor at #1 spark plug.
thanks!!

[supraII]

opps, disreguard that message.

[Frank_MA61]

I found a header that Trust japan/GReddy sells. Its not listed on any US websites but Im sure GReddy USA can get them. Its a 6 - 2 design with 42mm into 50mm tubing. It costs a pretty penny though....about $500 usd.

TR NA Exhaust Manifold.

And also a lightweight flywheel from JUN. Again its from JUN Japan, but im sure JUN USA can get it. Its a 12.3 lb aluminum piece. This might be of some value to us because im not sure If any other companies make lightweight flywheels for the 5M.

JUN Flywheel

[SilverMk2]

Hmmm. Never knew Greddy still sold any Mk2 parts, let alone a header. BTW you can get 5M/7MGE flywheels from Fidanza for around $350.

[Import_Eve]

how can you order from cyberauto.com?

[AlxRSPTT]

Call or place an order on the site. You just click on ordering on the Menu bar on the right. Ordering

[Tanya]

what about GUDE camshafts?
I know Wes has a write up on the AFM mod, I'll have to go get the link.
I dyno'd at 132rwhp 138rwtq w/ cut air box, FRAM air filter, shaved head, Pacesetter header, 1 3/4" mandrel bent exhaust, no cat, stock Celica muffler.
I have since upgraded the exhaust to 2.25" with a Dynomax Super Turbo muffler and I will post up new dyno results when I get 'em

[formulaone]

hello new here i just pulled my engine out of my 84 supra p type and am wondering if thier is a performance rebuild kit availabe for the 5mge engine
thanks

[williamb82]

nope, just the stock rebuild kit.

[jordansupra]

If I adjust my AFM four clicks how much is that going to affect my MPG?

found one online, up to 11 :1 pistons, and 89mm bore, heres the linky:
Nevermind, can't find it, was looking for a cheap price on a used 7m, and found a site that offered rebuild kits, and I swear it was go2motors, or summin' like that. Put in fav's, and then reloaded winders cauz I had an issue with the p.c., and now can't find it But I found a site somewhere on thewww. that offered a rebuild kit, performance oriented, was like 1300 $ for the kit, but haD everything but a camshaft.

Will find it and update this, pissed now.

[VanKillah]

Heh, linky:!!!:http://www.importperformanceparts.ne...ek-toyota.html

[VanKillah]

So, maybe I should put this in another thread, or start its own, but before i put the 5m in my van, I would like to go through its 225k ass, and was wondering if, or how much more it would be to go with the above rebuild, as opposed to a stock rebuild, and if I was just trying for 250 whp, should I even worry with a turb, and just use a 7m crank for the stroker effect, and their 10 or 11:1 option.

My car is a L 83 a/t, which will be a 5spd when in the 'crawler

[Kurplunk2]

sorry, but i'm trying to figure out how to put pics with our postshttp://C:\Documents and Settings\Own...ld C5 Corvette

[williamb82]

its a standard rebuild kit with custom ross pistons.

[splay]

was looking at rabid chimps throttle body anyone have one? is it just a bored out tb? or is it off another toy? i am planning on turboing a 5m and want to start doing what i can first before the great expense of the turbo setup

thanks guys

[williamb82]

there are several people on celicasupra.com that have this mod. it is a stock tb thats been bored out and a new throttle plate installed.
