5S-FE MK2 Non-Turbo Engine 3SGE Transmission to 5sfe

capeta · 08-16-2009, 12:48 AM

Hey,

I'm new to the MR2 world, and if this question has been posted already, I apologize...but after doing some research I learned that a 5SFE tranny will bolt on a 3sge right? (correct me if I'm wrong). Anyhow, if that's true then that means that the 3sge and the 5sfe both have similiar blocks right? (Threads, design, etc). Then couldn't I go around the other way? And bolt a 3sge Tranny to a 5sfe? Let me know if anyone has done this...

I'm pretty sure you can. I know that the axles for the 3sge are bigger and you might have to change the spindles? might depend on gens though?

the 3sge and 5sfe share the same gear box, the 3sgte on the other hand is different

TomsMR2 · 08-20-2009, 08:30 AM

the 3sgte gearbox also bolts onto the 5sfe.. but yeah, the 3sge and 5sfe both use S54 transmissions which are identical, except the gen3 3sge which has a lower final drive.

Ok while i'm reading this i also have a drivetrain question i have a 1991 5sfe motor that was just put into a car i bought with a brand new stage2 clutch and i have a somewhat built 1991 3sgte motor with a stage3 clutch. I'm doing a swap and don't think i need the pressure of a stage3 clutch so will the 1991 5sfe stage2 fit the 1991 3sgte tranny

no sir. Im pretty sure it doesn't. from what i've read correct guys?

you need a 5s pressure plate if your using a 5s

so does that mean the automatic tranny on my 95 5SFE will bolt right up to a 95 3SGE motor?

only on the euro spec tranny. the jdm tranny has the same final drive as anyother s54 tranny

as far as the auto bolting up, everything will bolt up fine however, i dont know if the flex plate will work with the 3sge and i havent seen an automatic 3sge mr2 (never really looked so i could be wrong)

mattdouken · 01-31-2010, 10:02 PM

Well since everyone is asking transmission questions, I will asks mine. A 3s-gte trans will bolt onto a 5s-fe.

Other than modding the axles what clutch/pressure plate combo is needed?

CJMR2T · 02-01-2010, 01:45 AM

The 5s clutch and PP but the disc will have to have the hub changed... the 1-1/8" 22 spline hubs fit the smaller discs fine... you can also use the disc from the older RWD celica and such with the 22R or RE engine... They had the larger hub but with the smaller 7-7/8" disc...

mattdouken · 02-01-2010, 12:02 PM

Could I just use a 3s-gte disc?

No, its too large in diameter for a 5s-fe flywheel and pressure plate. The 3s-gte disc is 9-1/4" where as the 5s-fe is 8-7/8".....

CJMR2T · 02-01-2010, 04:28 PM

Any clutch shop / rebuilder should be able to swap out the hub setion for you and it shouldn't cost much...

A little over a year ago, I had two of them done for a lexus V8 project I was working on which was using a custom built twin disc using a 5s pressure plate and disc's and a local rebuilder charged me $45 to swap both of them (basically $15 for each new hub and $10 in labor to swap them).

The problem is not the engine, its trans. The input shaft diameter and spline count was different with different trans's.
