By the time you get finished, you will have spent enough to buy a very low mileage Stage-3 Roush, GT-500. I realize you probably have your heart set on doing this, but unless you have alot of build experience, you are gonna be one unhappy, frustrated person. Go to SVT Performance and look at all the supercharged GT Stangs, 500's Roushes etc. that are for sale, and there are some dang good deals there.
