Ok I am looking to supercharge/turbocharge my 99 GT. I just raced a 02 TA WS6 with filter lid and cat back. I actully got him off the line threw the first three gears and once I hit 4th it was bye bye for me. I want to be able to just plain leave him and any other GM car in the dust. What should I get. Procharger, Supercharger, turbo kit? I want the cheapest best bang for the buck kit out there. Let me know thanks.
