i want to put an rx8 6-speed in my turbo II, closer gears means constant higher revs, but it might not be as strong at the drag strip, oh well. as far as comparing the t2 to the fd tranny, they are really similar on the inside. i have done many 8000 rpm launches on drag radials and 400+whp in my t2 and no problems yet, so the t2 drive train is really stout.
