Whats the best turbo i can get for $ and i saw zzperformance makes a nice kit but i want the most hp for the $ if you know what i mean. thanks

ZZperformance.com and pfyc.com are the only two turbo kits I've heard of. The one from PFYC, according to the dyno, gets 290-ish horsepower on an otherwise stock GT. The thing is, though, you're going to have to replace alot of stuff if you want it to last after getting the turbo, probably starting with the tranny.
