66mm or 68mm Throttle body?

[Luke Accord]

Hey all been looking around for a 66mm skunk2 throttle body for a h22a but not having any luck would there be any difference in performance in using a 68mm?

The H22 likes air. 68mm would be ideal, you could even go larger depending on the mods you are doing.

Make sure you get it ported to your IM otherwise there is not much use.

do what he says to benefit the bigger throttle body. Injectors not needed.

+rep point for you.

i beg to differ on the every car bit... this is why i was so confused switching from a Nissan SR20 to a Honda B16.... there are so many dyno proven gains from intake modifcations on the honda BUT i will guarantee you there is little to no benefit in TB/plenum/runner design on an sr20 until at least a certain power output.

i don't agree with the injectors either

I got a custom inlet manifold made up with a larger 70mm tb and i went from 96kw atws to 110kw atws. So there is some gain to be had on sr20's. Just not as much as the honda guys.

The engine is going to have stage 1 skunk2 cams, springs and retainers, custom CAI, e-manage, Headers 2.5 inch exhaust.

The 68mm will be a little bit of an issue on a stock manifold as you will run into the idle air valve port when opening the manifold mouth to suit the 68mm throttle body. You might have to invest in a skunk manifold as well.
