I talked to a local mechanic not too long ago about the infamous 3S-GTE swap and he suggested something a little different. He said that instead of using a 3S-GTE, use a 3S-GE and beef up the bottom end and boost that. This engine is bigger (2.2 compared to 2.0) and puts out better torque, especially in the low-end range. He said that they haven't done this in any Celicas, but they have in several MR2 turbos and it worked better than building up a 3S-GTE.
Let me know if anybody has tried this or what you think about it. |

SC's on a i4 car are a waste of time IMO:p, the whole takes power to make power thing is a little stupid for an already relatively torqueless engine(ie most i4 engines). but they are less stressfull on the entire system. how safe it would be depends on the engine's internals, i have read in a few places that the 5sfe internals are reliable to 250hp and no more. 6psi wont put you that high. a guy on celica.net ran 5psi non intercooled on a ST for several months, then 12psi intercooled for a few more months, then the last week before he got his supra TT, he went up to 25psi. at one point his oil return line broke and all the oil drained from the engine and the lower radiator hose blew off. he refilled the fluids and the car ran fine. eventually the head gasket blew but all he had to do was replace it with the stock one(which on the 7afe is metal, unlike the 5sfe) the problem high compression causes is detonation, which can be counter acted by putting more fuel into the engine. it makes the setup more complex and requires a lot more fuel causing a loss in efficiency on that side but the higher CR make for more power gained per psi so yes, a full rebuild would be ideal, but i would not want to drive such a powerful fwd car, i have a friend with a srt-4 who switched over from a 95 GSX. you wouldnt believe how much he complains about traction. doesnt mind the better rolling response though i do agree that high compression is a problem(kinda glad i have an ST instead of a GT), but its not the biggest problem. knowledge, maintainance, and tunning will keep any engine going with any *reasonable* setup. -------------------- 1994 Celica GT4 WRC Edition
