YES! the H23 head does fit on the F22ax block..

[4thgenaccord]

So I was looking more at the motor at the shop. it's not a H23 it's a B21A1

Damn it. anyway to make this work with the F22Ax motor?

Note: ONLY the head is good. the motor is shot.

Ok, wasn't sure.

Figuers. I never get lucky. Well, guess I'll be sticking to my stock motor.

alright, so i kno that i need a new crank gear for the h23 head swap, what is the difference between the f22Ax, f22B (jdm prelude) and h23 crank gears? I have an f22b one, will that work? also f22b I/M? I also have an a6 intake mani if need be but the f22B one is mint and i would rather use that. I see no reason why it shouldn't work.

If you build this and you run an P14 ecu, what do you do about the knock sensor?

you'll have to put one in the block...

I still think just putting an H23A IM on an F22A will give you the same power... the cams aren't that aggressive, and I don't think the DOHC head flows any better

Well, your theory is just that, a theory.

I have an H23 IM/tb, in a jdm f22a. WITH a 272 regrind.

In no way is it faster than my dohc. And my dohc is basically this head swap, with the exception of the compression difference. But most people make that up by milling the head.

bump...again! this is a NICE DIY..is shoud be in DIY! for the description !

[musteredonme]

im really concidering this swap if u could send me a PM on what i need from the junk yard on what i need the ECU is gone but im not goin too swap everything at once over time let me knwo thax

[moe]

this is pretty sweet. im thing im gonna do this.

how much of a gain do u think ull get out of it?

[CB7lx91]

If done perfectly, with a grand ol' tune up, the common butt dyno says around 160 hp. This hasn't been dyno'd yet though

[moe]

well that sounds like a pretty good gain

i think this will be my next mod to my car
