don't do a half ass job dude save you'r money up get you'r motor built. so you can run 10 pounds on the street and at the track run 30 pounds. and get it tuned. i mean tuned real good. remember if you just go out and buy a turbo slap it on your h22 and get it tuned and run to much boost or when you'r boosting your boost jumps you'r going to be wishing you had a built engine
