Hey guys,
This sort of goes with this topic... what size throttle bodies came stock on a '99 GTS? I have ported the stock t/bodies to smooth flow and match ported the intake to the t/bodies. I have a set of 1.7 MP rockers on the way and I am pulling the heads to do a mild port job. I have a custom grind cam from TNT (555 package), stepped hedders, no cats, TNT cat back exhaust (3 1/2"), 3.55 gears, underdrive pulley (25%), VEC1, and smooth tubes to conical k&n's. Would stepping up to a set of 70mm throttle bodies help out much or am I better off where I am ? I am painting the car right now and the hood is off. I keep looking at the engine compartment and wondering if throttle bodies would help or not. Bigr1, I didn't mean to steal your thread, I was equally as curious as you....I hope you understand. I have the factory street hedders with covers, Roe smooth tubes, K&N's, and the factory air box sitting in my garage doing nothing except collecting dust. If any of those pieces would do you any good, shoot me a e-mail and I will make you a wonderful deal to make a pathway through my garage. Any comments to my questions would be a great help.
Thanks,
Joe
