Default 62mm or 65mm throttle body with skunk2 intake manifold

in a 97 civic gsr...
will there be a big difference in using a ITR throttle body which is 62mm than a edelbrock throttle body which is 65mm with my skunk2 intake manifold? anyone have it on their setup?

i think the skunk2 intake manifold has a bore size of 64mm? correct?

btw..im going to turbo it sooner or later.

ITR is 64mm... and you should use a TB that is that size or over that size for the manifold... if not then the TB will be a bottleneck

hmm..i always thought it was 62...o wells.. whatever...

i also thought about gettin the edelbrock TB and boring the skunk2 IM to port match TB.
anyone have any clue on about how much it would cost to bore the intake manifold 1-2 mm? i know it depends on the shop but just want some experiences from people...

boring your manifold for a t/b will run you 50 bucks. try not to pay any more than that.

Why don't you bore the GSR throttle body instead.
I can bore it to 64.5mm and it will work just fine with the skunk2 manifold.
It will only cost you $100, click on the link on my signature for info.
