Is there anyone on this site who has successfully done (or have done) a 3SGTE swap with a GT4 manual tranmission (converted to front wheel drive: NOT all wheel) on a 6GC without losing power to the wheels ??? Or, did you have to get an MR2 tranny since its just front wheel drive?

Thanks!!!

gt4 trans are made to put power out to all 4 wheels... by unbolting the transfer case and putting something to close off the diff you would only get half the power put out to the front wheells....


Yes the mr2 turbo trans is your best bet... painful to do and its not cheep but yes I have done one on a 6gc.

Wow Capslock alert!!!!

Stehn is currently in the process in making the ST205 gearbox 2wd. Its a real PITA and you need whole kind of different parts. MR2T inner axel's en ST205 outers. And then still a bit of custom work. But MR2 tranny has been done several times as well. If your powergoals aren't above 250 whp a 5S-FE or 3S-GE tranny will be sufficient enough.

i currently have one that has successfully converted to FWD and has beed used in a 300 hp 3sgte and i bought it converted and with a cusco lsd check out this thread 3sgte tranny pics

Not to be rude, but I think you got some bad info on that one.

The center diff on the alltrac trans sends power to the rear wheels after the front differentia. The E151 (Alltrac) and E153(MR2) trannies are mechanically the same - same housing, same gearing, same input shaft. Toyota made one casting and added the option for the center diff.

ST205 doesn't have inner/outer axels. They are one piece.

remember when we all tried to warn you this would happen?

Thanks, yungazzdriver, for that info. My car dyno today at 205WHP on just 6 pounds of boost since I did not have a boost controller to turn up the boost. Once I get one, I will retune at 15psi which will give me just about 300whp (the same as yours). Are you running 14 psi or 15 psi?

Thanks, everyone, for your input!

Dont think you will get 300 whp with 15 psi. Defgeph is running 17,5 psi and has 245whp

You should be able to pick up a busted E153 on the MR2 boards. You can then convert the tranny using the parts from the two transmissions together. See the link form earlier in the thread.

Use the ST205 case + gears (better synchros), and the diff + block-off plate from the MR2. Also, think about putting in an LSD at that time, since you have to pull the diff out anyway...

At 15-17psi you will be getting around 250whp +/-20hp with an intake and 3" exhaust.

has anyone looked at his mod lists in his profile? i think hell be at more than 250 wheel..

I will let you know when I retune at 15psi.
