What Size Throttle Body?

[stng]

I am going to change out my throttle body and plenum this month, I have a couple of questions...

1. What brand of plenum and/or throttle body will yield the greatest results?

2. What size throttle body should I go with, 70mm or 75mm?

3. What additional parts will be required (pcv tps ect...)?

4. How hard of an install is it? Anything I should know before getting started?

Thank You all in Advance

I love my Accufab 75mm TB and Plenum. Quality with a touch of bling.

70mm for N/A


75mm for F/I.

70mm Accufab and Accufab Plenum.

75mm all the way around. No real power loss over the 70mm and if any major mods are in the picture, the bigger T/B will help you realize them.

105 mm 5.0 t/b with ported accufab. isn't bigger better ?

oh i forgot... i ain't a chevy boy !!!

just had a c&L plen and 75mm accufab tb installed this week and im very happy with it..i didnt install it myself though so i cant comment on ease of install.

Definitely go 75mm.

Install takes less than an hour the first time. Here's the step-by-step:

here's a comparison on some brands of plenums http://www.modulardepot.com/?show=articlesdet&aid=38 good read.

i have a 70mm, and bf has 75mm. not much of a difference i think, i need to dyno mine though now. we both have accufab throttle body & plenum
