So with my 02 gt I have k&n intake, bbk shorty header, bbk x pipe, flow master exhaust, 3.73 gears, coils, and 100 dry shot nos. I just order a pulley set and had questions about what next. What size throttle body? I was looking at AM's bbk 78 combo with the upper. And then I was thinking injectors maybe?? Short shifter??? Opinions???
