Im trying to decide between 65-70-75mm throttle bodies. Im running a Vortech SC-trim @ 11 psi, Typhoon intake, full exhaust, 73mm C&L MAF and a 50-shot. Im about to buy some alum heads (probably AFR) once I get a TB and a few more supporting mods and swap to a turbo setup. Thanks,

Cody

sweet. i heard going 75 will hurt performance but I guess under 15 lbs of intercooled boost it will flow fine.

The TB size with a forced induction motor really makes no difference...between 65mm and 70mm...Do you want more throttle response in lower RPM's? if so go with 65mm if 70 would be my choice since it works well with the intake opening...75 WAY too big...
