Throttle Body and Plenum 70mm or 75mm?
Planning on getting a trick flow throttle body and intake plenum for my 02 GT. I read somewhere that a 75mm throttle body is only good for cars that are heavily modified because a bolt on GT does not flow enough air to benefit from a larger throttle body. My car only has some minor bolt ons (CAI and exhaust) and 3.73 rear gears, but Im rebuilding the engine in a little over a year from now. Would I be alright with a 75mm throttle body or should I get the 70mm?

I've got a 70mm, some people think a 75mm tb is overkill and could actually give you less power. Idk about that, but my 70mm made a noticeable difference for me (minor bolt-ons). If you plan on going f/i, I'd just get the 75mm.
