View Full Version : 5sgte MR2 and celica gts 3sgte

Ok just picked up a NA 1992 MR2 with the second gen 3sgte motor and trans with ECU/wiring harness.

and Im having a fully built 5sgte done up so the predicament is to put the stock 3sgte in the celica with my aftermarket manifold and stock ct26 turbo and just run with it.

and for big power do my 5sgte in the MR2 for massive power gains.

if I go with 3sgte in the celica what has to be done to run the stock 5s trans. would be willing to buy another mr2 turbo trans later on down the road but getting out of military soon so lets keep it simple for now. Low boost and whats the max hp on 5s trans.

Open to thoughts.

I ran my stock 5s trans on a 14psi 3sgte for 6 years with no problems. Just don't beat on it and you will be fine.

I blew up several s54's. Just sayin.

Isn't the 92 trans the S53?

I didn't think they brought in the S54 until 94.....

the stock 5s tranny is a ticking time bomb with the 3s. Some last for years some last for hours. If your tranny is in excellent shape and you don't beat on it too bad you should be OK for a while. MR2's with big power are lots of fun!!!!
Plus IMO why have a 5sgte in a FWD car when you could have it sitting behind you driving the rear wheels?

You just need to make sure you put a 5s smaller spline clutch disk in or you won't be going anywhere! lol This happened to the people I just got my caldina swapped 93 from.
