what gear box Options

[yellowchinaman]

One for the tech heads.
If I wanted a 6th gear for a higher top end.
What alternative gear box can I use for the ST205 GT4's which can be mated with the gen3 3SGTE?

as long as the year of the transmission from the camry matches the year of the transmission on the GT4 it will be bolt on affair, actually you don't even need to remove the transmission from the car since the 5th gear can be access by removing the.. 5th gear cover .. the small cover at the end of the transmission on the left side.

complications ? if done correctly none, I would advise to replace the gear synchro at the same time.

if you do remove the transmission and want to have a newer transmission all around, you can open the ST205 transmission and use a Camry v6 ( the newer the better )

if you use the camry transmission ( V6 manual ) you need the differential from teh ST025 transmission in the camry transmission and bolt on the transfer case to make it AWD, this will give you slightly longer gears rather than just 5th gear, all gears are either euqal or longer, I knwo for a fact 3rd gear is longer and so is 5th gear, the top speed on standard tires of this transmission is ~ 167 MPH, some MR2's have achieved ~ 180 with larger tires.
