Ok, so I have a f22b2 engine and I want to put an jdm f22b dohc head on it. I've read that the f22b dohc is basically the same as the h23 head, but how similar are they really? Its really hard finding a f22b head by itself so I might just end up buying the whole engine and then parting it out. I'm wondering what parts are interchangeable that i should keep. Would it be better to use the h23 intake mani or exhaust mani or are they the same? Which ecu would be the best choice considering that I have to keep it obd2 for inspection. Would really like to hear from people who have already did the swap or has this knowledge. Thanks.

if your'e going to buy the whole f22b motor to part out just the head, that would be foolish. swap it out for your f22b2. the intake manifolds and exhaust manifolds on the f22b and h23 are the same.

the reason for just keeping the head is because a full engine swap is illegal if its older than the car, forgot to mention i have a 96 cd5. i was told that its legal to do headswaps though.Comment

yea but if anyone knew that f22b2 never came dohc, they would raise the red flag.Comment

well in california, headswaps are also Illegal.

x2, it's mainly california, washington, oregon, new york, new jeresy. places where they've had people try to pass every swap known to man. in NC, where i'm live, most of them only know the major honda swaps if even that.Originally posted by wed3kComment

Now I don't know a whole lot, but I'm pretty sure if you're worried about inspections you can't do a JDM head swap, as it's the emissions shit they're worried about and as far as I know JDM motors don't have like an EGR and shit like that..Originally posted by che3se
As far as the choice of heads, I wouldn't choose an F series head over an H, but I don't really understand what you're asking..Comment

Well, the f22b dohc well b a simpler procedure and produce basically the same results as an h23 head if bolted on to my f22 block + i assume it'll be a bit more reliable since the f22bx blocks r the same block. I was basically asking what parts i could use and if any parts would produce more power if i took them from an h23. But I've made a thread talkin about the legal issues in NY and i'm having second thoughts.Comment

geez here in texas all u have to do is go forwards, backwards, honk 3 times, no cracked glass(headlights, windshield tail lights) and pass a very very easy emissions test and ur good to go. My 92 integra with 2 1/2" exhaust with no cat, resonator and a shitty muffler passed emissions lol. No visual inspection other then the glass thing. They dont care what motor is in it and nor will they ever.Comment

Actually the F22b head and the H23a head are slightly different. On the jdm F22b head the exhaust valves are bigger than on the H23a head.Comment
