If you want a GS-T...sell your car and get a GS-T. Think about it this way. You sell your car ( RS ) and spend like $3000 more for a 99' GS-T. You would not only be getting the 4G63 engine, but power everything, a sun roof, side skirts, 16' rims, fog lights, a high rear spoiler, better sound system, sport suspention, and white face gauges ( I'm not sure but I don't think they came on the RS?? ).

But that's if you want a GS-T. If you want to keep your car cause you already spent bones on it, and you don't wanna get rid of it...then I think you should get a Stage 2 turbo kit and not boost above 8psi. Cause at 4psi, you will be faster then a stock GS-T and at 8psi, you will KICK ASS!!!! just my 2 cents.
