Hi guys,
I need some advice on what size throttle body and mass air meter to go with. My car has BBK equal length shorties,BBk crossover pipe with high flow cats,flowmaster cat back system,mac cold air intake, and 3.55 gears.I am looking at the Pro M 75mm mass air, but not sure which throttle body. Will a 65mm be too small with aftermarket cam,intake and heads? I plan on installing these eventually. Will a 70mm be too big with out these mods? Any info would be greatly appreciated.
