Yet Another IS200 to be Turbo'd
Yet Another IS200 to be Turbo'd
I too want to go down the turbo route, but need help and advice as I go along.
From what I have read, 4-6psi boost is the max the stock engine can take - given the toothpick conrods.
Also no ECU needed upto for this level of boost, just a map sensor voltage clamp - the black box as sold on here by P.Lindblom.
Just need to construct a manifold - probably log type.
Get a turbo - T28 with adjustable actuator set to 5PSI
Construct turbo out pipe to mate to catback exhaust as sold by 2fast2cool2 on ebay. Exhaust already on car and sounds great.
Engine is still healthy at 95K and just had a full service. I'll do a belt change in the summer. Doesn't use any oil and still pulls well. Just had MOT so all in all - good nick.
May need a clutch, so what uprated clutch assembly do you'll use? I had read/heard that std Celica GT4/MR2 Turbo pressure plate and drive plate is a bolt on! Can anybody confirm?
Also read that Celica 1ZZFE green injectors are a direct bolt on with a very slight increase in cc? Do they help and not over fuel with just the blackbox?
Probably more questions to come
Cheers Guys

You'll prob have to make a tubular manifold. A log is generally cast so mass produced.
Injectors do for your right. And your best going for something like the emanage ultimate to be honest.

A big issue of "safe" is map and heat, so if you sort cooling out, you might be able to push a bit more boost and remain in safe territory.

good luck with the build expect sleepless nights and a bauld patch from standing back and scratching your head ha ha ha
Good ideas bud get some pictures up. i was originally looking to make my manifold log style but in the end I got a cheap 2jz manifold an chopped the flanges off an welded 1gfe ones on , but now ive got all the bits to make a log one im going to try that when I get the time they dont win any awards for being priety but they work .

Haven't bought anything as yet, just making lists and doing research as don't want anything to go horribly wrong.
So 0.5bar/7psi should be safe.
Still need to know about clutch as I'm pretty sure my current one won't hold up.
What clutch you using John?
Cheers guys for the info.
