doh! aww man...a supercharger would've been pretty fun actually, i think i actually bought it from fast4dr cuz i was looking through the old archives and his sig at the bottom is the person i bought the car from. eric flecha working at ritterpen. i got the build number like matt said and just searched and found the build number in his sig. man...i'm looking to get a turbo too and if the car came with it i would've been all set. ACTUALLY, i wonder if the car has headers since he had a supercharger in it
