I wasn't to sure. I know they are both 2.0 motors, but don't want to waste money getting one. So, any advise would help out a lot. BTW I have the ST model, just want a little boost in speed.
yes they can but you might run into clutch issues. Mafix will know forsure. IMO, not worth it if your current trans is working fine. changing to a s54 trans with a 3sge motor, not that might be worth it
Depends, what 3SGE gearbox do you want to fit. All 3SGE gboxes should fit your motor, however the only one that will bolt on and work is an S54 from either an ST182 or ST202, or from a 3SGE powered MR2 (note that the MR2 will require FWD linkages and mods to get the FWD linkages on however) You can use a gen 1 3SGE gearbox from an ST162 however the problem is it won't have the hole to bolt up your exhaust side starter, it is cast as a blank. I have heard of people machining this out before to the standard FE gearbox specs, and it worked fine. The other option is to use the complete flywheel and starter assembly from a 3SGE, but you may have exhaust issues with it fouling on the starter. Driveshafts from either should have the same splines, and I'm 90% sure the clutches will be the same. Best option is to find a later 3SGE gearbox, or machine the hole in an earlier one. The other option is a S54 gearbox from either a Celica or Camry with an S54, the ratio on all the ones I've seen are 3.944, which is pretty much half way between the GE's 4.176 and the 3SFE's 3.7xx and might be a good compromise
so what is the recommended transmission to put on that will give me a boost that will bolt on and work?
If you can find one, an S54 from a later generation 3SGE. Next best in my opinion would be a low-km S54 from a 5SFE.
