Just curious ? how is it a better TB ? for reasons 1: money not needed to spend
2: how much bigger in size is it
3: the TB doesnt matter the manifold and the head only flow so much cfm unless you do milling and boring out of the head and IN manifold so what can be expected out of the f22 TB.
4:even with milling what are you hoping to gain 1-5 hp not really worth it IMO.
5. Maybe motto will chime in.

hmm..all i said was that it bolts on...and i got it for free and didnt have a tb........thats one thing that makes this good is because there is some aftermarket for the f22 so we have atleast a small selection...

I think this was previously discussed. I dont remember the specifics but its only marginally larger than the lude TB. Yes you need to machine the intake manifold to get the best benifits from it. If one was to do some research on an aftermarket f22 TB and see how large they go that would be a substantial benifit but then again it wont make a difference unless you machine the intake manifold. For a cheap alternative TB its not a bad choice.

Yes , (sully) I know but he had stated the he was just replacing the TB and not milling the head or intake manifold. Also that he got it for free and he just wanted to see if it worked but thanks anyway.

f22 tb has aftermarket tbs at 68 mm and it wouldnt be too difficult to match the IM to it...my intake mani and tb will be bored out and ported and polished along with the head. Ive been reading on this and im pretty sure the h22 tb will fit too..and i know that a b18 one will fit it you just redrill the bottom hole closet to the firewall just alittle higher....

Most intake manifolds are design with MPG in mind, thus they start the engine from much needed air intake.

Upgrading the TB, opening the IM will net a nicer throttle response and help aid in the small power curve the B20A has. It will only produce 1-5whp at peak but if you're concerned with peak numbers, buy a B16/civic.

The H22 has seen 12 or so whp with a better IM and stock head... hmmm
