before you transfer all the parts, try them one at a time. take the motor out of the supra first then put it in the RSX, if it works take the motor out and try another upgrade. if everything works individually then you messed up somewhere in the installation. try the supra stock and see if it works ok, if it does try reinstalling everything together again in the supra and see if it works better. if not take the drive train apart starting at the wheels. take them off, then see if it works ok (obviously you wont run it on the floor). if thats the problem you need to loosen the wheel nuts some. then take the rear differential out to see if the front is causing the drag. hold it up and hit the throttle and let go, if one side of the front stops eariler then the other you need to loosten the differential. do this by holding the side that stops later and play with the throttle. (bring it up and down) then let go and see if that side still stops earlier. then do the same thing with the rear.
