go to sccoa.com and go to classifieds you can find supercharger kits from thunderbird sc's minus like a few misc. things for like 400 bucks best deal you can find as far as forced induction. They also have many parts on that sight for the 3.8 supercharged engine that will really get you going. I used to have a 89 sc loved it, fast car for how heavy and old it was. I would go that route. I have a 98 gt with most bolt ons and am thinkin of doing a 3.8 project car and going the thunderbird sc route i want to see how fast i can go for little money!
