so i am about to purchase the Skunk2 Pro Series intake manifold and i wanted some opinions about getting a larger throttle body (one in question: skunk 2 68mm). I currently have intake, headers, free-flow cat, cat-back exhaust 2 1/2". I also plan on upgrading my entire fuel system after i complete my I/H/E and electrical system shortly after. After installing the upgraded intake manifold, would this 68mm throttle body do me more good or bad? if bad, what would be the optimal size?

 

why not just bore out your stock one? cheaper than buying one.

ok, but would 68mm be a good size, or is that too big?

 

I've heard with out boost that large of a tb is a waste... Just what I've heard.

 

i read some dyno charts on bigger throttle bodies and i wouldnt go bigger than the 65mm.. type-r is that size... the bigger throttle body will increase your top end hp but you will severely loose low end torque... which a honda motor badly needs..

 

I have also heard that upgrading to a aftermarket intake manifold and throttle body is best if your going boost... if not you don't realize much of a difference, maybe a tad, but they usually maximize power between a certain RPM band when your car is boosted....
