70mm or 75mm TB?
 

i mailed my broken and un-wanted gold to dollars 4 gold and got $400. anyways, i need advice on buying a new throttle body. i have headers, 2.5 exhaust, UD pullies, and a K&N filter. i am planning on getting heads, cam, and intake later on in the future, should i get a 70mm or 75mm TB?

TB selection should be made based on the inlet size of your intake. Since you are going to replace the intake eventually, you should choose which one you want, so you can properly order the correct size TB.

or wait and do it at the same time

if ur doing upgrades to the engine get the 75mm. i run a 90mm lmaf w/ a fms 75mm tb

do you think my car will still gain hp, or run ok with the 75mm right now? i heard if the TB is too big it runs bad.

do waht addermk2 said.........you won't feel the gain if that's what you hope
