I was wondering about the H23 head/F22a6 block frank. What type of horsepower can one expect from it? Is the horsepower gain really significant? I was just checking cuz I was thinking about doing it but if the gains ain't even that much then I'm gonna go head and save up some more chips for F22b DOHC or H22 full swap.

well youll be having a head that normally would be on 10.1 on a 8.5.1 block and im sure the gains wouldnt be worth it stick it out keep savin and get the full swap h22 is alright stock but youll get it and need more!!!good luck man keep posted on what you do and do the h22 more torque...
smoke tires, not drugs. -
F22A6: 142 lb/ft @ 4500 rpmOriginally posted by slammed4thgen
H22A: 158 lb/ft @ 5500 rpm
in all honesty, the H22 doesnt have THAT much more torque than the F22a series.
but for the OP, check out the members ride threads for people who have done the frankenstein swap and ask them what they think, was it worth it....etc.
then you can decide for yourself if you want to do it or not.

true torque is what makes the ride enjoyable!
i've heard guys switch from street bikes to chopper style bikes because of the torque!

check out lowdollar's member ride page i believe he has a frank engine+turbo putting down serious power

There's really no reason to make a frank engine, unless you're just trying to be different. Reliability is seriously compromised in most cases (especially for those that aren't experienced), and the power gains aren't all that significant. The H23 makes 20hp more than the f22A6 with .1L more displacement and 1.5 points more compression... Factor that in, and you'll find that the H23 head on the f22a block won't give you much horsepower. If you make 150 at the crank, I'd be impressed. For all the costs involved (h23 head, all gaskets, fluids, belts, ecu if you wanted...) you could afford something that made better power for the F22A... perhaps a Bisimoto header. That header, along with a decent intake and exhaust, would probably make about 160 crank hp from the f22a.

i actually like the powergain and the range rpulled alll the way past 6000. just that i was smoking because of headgasket issues. all my friend's drove it with the headswap and now back with a stock f22 and they said that there was a pretty big difference.
mind you this is a f22a6 with intake and exhaust compared to a h23 headswap, chipped p06, h23 manifold, DC sports header and a lot of bolt ons.
trust me, there was a good difference and it feels so much better to have your power come on at 3k instead of when vtec hits. so from that, you can understand where i get my opinion with vtec motors.Comment
