Throttle Body

[SCPLOWBOYO1]

Is it a goob ideal to put a h22a throttle body on a f22a6 with cold air & HPracing header?

If it fits, sure, except that the the bore on the upper plenum would have to be bored out to match. But there really isn't enough material there to do it. A better idea is to remove the upper plenum and replace it with the one from the H22 engine that the TB is coming from. No machining fees that way either.
