need your opinion
 

i have a 91 n/a should i put in a 2nd gen tII, a 3rd single tubo or a 3rd TT. i know a guy who would put a 20b twin everything i need to run except uts an auto tranny but that one setup would cost me like 9,000 what should i convert it to??????

20b, if you have the $9k. If not, just get a s5 TII engine. They just bolt in. Remember though, you have to modify the entire drivetrain, no matter which you do.
