Throttle Body

donny82277 · January 26th, 2007, 04:22 PM

Can you change just the throttle body or do you need a plenum also? if so is a 70 or 75mm bbk right for a 03 Gt as an upgrade with headers to follow.

70mm unless your planing on some kind of forced induction later on. then go 75+.
You dont need a new plenum to go with your TB. If you want more gain then get one. Or just get your stock one drilled.

The TB is worth very little on a mostly stock motor. I think they are worth about 5-10hp if you are putting down over 400.
