im not doin nuttin big 2 da motor jus yet.. i jus wanna hav a lil more power until i get my H22 turbo....

The head from the f22B1 (which is what you want to put on there) is SIGNIFICANTLY worse than the stock F22A head. Instead of wasting the money on the head, and risking the reliability issues involved with such a swap, just get some porting and polishing done to the F22A1 head, and slap in a $100 Delta 272 cam regrind.

Please don't be yet another person to fall victim to the "it's vtec, so it must be better!" scam.

so putting the F22b sohc vtec head on the f22a block is not a good idea...its a waste of time?? or will it give me a lil more perfomance??

Honestly you really won't feel it.

its a waste of time?? yes it is.

or will it give me a lil more perfomance?? No. Maybe 5hp but all that work for 5hp aint worth it. if your looking to do a head swap get one off a F22b or a H23(F22b is the JDM DOHC version of the H23). less time. less custom work. less hassle.



take a look in the technical and swap sections. you'll find a lot of info in there to help you along the way

The F22B1 head flows terribly. The "VTEC" is for the intake valves only. This is not a SOHC H22... it's meant for fuel economy, and the VTEC gimmick to sell cars.

wow, what replies, i was looking forward to doing a f22b1 swap. but now, i dunno.

if you have a A4, swap in some A6 cams and drop in a H23 manifold. less time/work for increase in HP.

fixed dont want him thinking the a6 is DOHC. lol

First of all I have a complete f22b1 swap personally it performs better to me anyways, just get a chipped p28 and your fine alot people on this sight talk alot shit on here about that motor if you want to do it then go ahead its your ride your money do what you want. Check out Samuri88 Acclude91 and Turbo 2.2 they have f22b1 motors im trying to get MR thread going,just keep a look out.

He's not swapping motors. He's doing a headswap. Swapping a B1 head onto an F22Ax block is retarded.

The specs of the blocks are about the same. Still, headswaps are a pain.


The F22B1, the full motor, makes 5hp more than the F22A6. The head flows very poorly (as does the F22B2). The VTEC system is not made for performance, and is implemented on the intake side only. The exhaust ports are already restrictive, and can only be opened so much.

If you want fuel economy, go for it. If you want a reliable engine, go for the full F22B1... not a headswap. If you want power... you can always boost it, but then again, you can boost the F22A just as easily (actually, easier... the DSM manifold doesn't match the F22B1/2 ports as it does with the F22A).



As Darkcloud says, do what you want. However, make an educated decision. I'm giving you the downside to it. I honestly don't know if there IS an upside.

you tell em Deev. lol


there are a couple of other members up here with that MOTOR swap. but not the head swap. its not worth it.

i was looking at Project Car Mag and they had a CD5 in there with that same motor in it. it responded well to mods. but i bet the the a6 would have responded better to the exhaust and intake mods due to the cylinder head properties. especially that nitrous kit they put on

but if you want the SOHC VTEC, get the motor man. not just the head. i wouldnt mind having that motor myself too.

xfactortype1 has the headswap. He likes it. However, he's content with keeping it fairly stock otherwise.

$150 spent on a Delta 272 and an H23 intake manifold would make a MUCH bigger difference.
