3S-GE to 3S-GTE conversion Options

[bdawgbp1]

Does anyone know what all is involved in converting a 4th gen 3S-GE (American version rated at 135 HP, 125 ft/lb torque) to a 3S-GTE? I've gotten my hand on a 3S-GE out of a 1988 Celica GT-S that was rebuilt 90k miles ago and I want to convert it to a 3S-GTE. Any ideas? Thanks a bunch!

I would say a full rebuild of that motor since it is so old, you don't want to blow it after a week of driving under boost. If you rebuild, upgrade the internals with some forged pistons/rods. Get some pistons that will lower the compression ratio so you can handle more boost. A lot of the other stuff has been mentioned: exhaust manifold, intake, intercooler, stand alone ecu setup of some sort, access to a dyno, you'll definitely want some gauges for boost, oil pressure, EGT, etc. You'll also need to fab up most of the intake and intercooler piping. Oh and of course you'll need the turbo, whatever seems fitting to you but nothing too big.

What tranny are you using? IMO adding a limited slip diff would be an excellent idea, but could be done later. Oh and you'll definitely want to get a stronger clutch.

I'll post up if I think of anything else.
