what other mods do you have on the car? if no other mods then forget about it. even at best 1-4whp is only gained with those that push 180+whp

What a throttle body <u>will</u> do is improve throttle response...

Does anyone know what size the factory prelude throttle body is? It looks to me like it can be bolted up on a B-series? And also i was wondering what size is everyone running, i think 70mm is to big, ppl are just all about that cus SPOON makes one.

So if anyone feelslike recomending a size i would apreciate it,

12.2 compression, ITR intake manifold, full valvetrain, CTR cams, VAFC
thanx

Actually even with 0 mods a larger TB will give you a more responsive pedal. Reason being the there is a larger opening and more air can be inhaled with a lesser throttle Position...
Exactly right! That's a classic definition of 'better throttle response.' Thank you!
