Hey...I have a '93 B13 SE. My goal is push at least 500 hp at the wheels. (btw is that the same as WHP?...wheel horse power?) I am close to doing a bb u13 SR20DET swap. The Garret GT series is starting to look like a good swap for the turbo, but IDK. I'm new to turbos. Can I achieve my goal with the turbo that's already on the sr20det? is it worth changing? let me know. This is my first real intro into the world of forced induction. BTW...the stickys are really helpful!
