one more thing, my own two cents, I would personally go with a supercharger rather than turbo. from what I have found is that when the turbos spool traction is a MASSIVE issue. true there are guys out there with turbos on our cars in the 400 club but they have ALLOT of tire spinnage. I have driven a supercharged saturn, much more fun, no lag, it ran 12.5 un tuned and had allot more in it with tuning. In my opinon superchargers have less gremlins and are more fun. plus you still get the cool blow off valve!
