Re: Throttle body questions
How did you make a stock Honda TB 78mm?!! I'd like to see some pics of that.. Even an ITR TB ported to 68 is like paper thin.. I don't see how there could be 78mm there to even port out?!!?
Kunundrum - Look around for a used ITR TB if I were you, you can pick them up pretty cheap and they're cheaper if you get a used one than any aftermarket throttle body. Pretty much the same thing. forums.clubsi.com has a pretty good forsale - Canada webboard if you're looking for parts like that.

Re: Throttle body questions
I just knocked like 5 or 6 mm out of mine, I got it bored out to 60 mm and did a little work on the ports on the head, should be nice once I get the car running again, cept I'll be running the stock cam again
