your best bet is like stated above. buy some slightly used turbo parts and pay someone to put it in if you dont feel comfortable doing it yourself. i threw the greddy kit on my GSR and after the clutch, all turbo parts, and $700 for the install, my car went from 148hp at the wheels to 216 (all these numbers on a mustang dyno). I spent 4k for it all and also got some new wheels in that price. my car went from running a 15.5 in the 1/4 to a 13.9. It is still a daily driver and I'm only pushing 7.8lbs. My gas mileage only went down 4mph with the bigger injectors also.

So my .02 is turbo. its amazing
