T/B Size

InitialB · 03-08-2006, 04:09 AM

I have been adding a few bolt ons to my 04 this winter and I am to the intake portion. I have a professional products intake plenum and JLT CAI My question is what size TB should I get 70mm or 75mm. If anyone could help me out I would appreciate it.

Most people say 70mm for all motor, 75mm for forced induction. Ive got a 70 and id say just go and get a 75mm anyways.

Get the 75mm, It won't hurt w/o the blower, plus if you do eventually ge t blown, you'll already have the bigger tb.

Personally, I dont really see why you would get a 70mm TB. I mean, I know why, but most people who would get a TB would already have some other mods (catback, CAI, etc.)

If you look at his sig you'll see he's got a cat back, x pipe and many other mods......unless that is a "to do" list. Anyway, I had a 75mm TB on my N/A 03 GT and it worked fine. I don't know anything about the Professional Products plenum, but I had the C&L plenum and the 75mm TB worked best with it according to their dyno tests. So maybe do some research and see if their are any tests with the Professional Products Plenum and different TB's.
