    I have to say that I am very impressed with the knowledge that floats around in here. I have a 92 camaro that im working on (but chevys are easy) and also a 93 accord. I don't know much about hondas and of corse am trying to get more power out of mine. Everyone's blah blah blah h22 swap blah blah. I get tired of taking the easy way out and just swapping motors. I would like to build the f22a6 i have and the whole f22b head thing sounds easy. Besides some ecu work is there anything else to complement the swap. I.E. cams or something. PLEASE REMEMBER I DONT KNOW ALOT OF AFTERMARKET HONDA PARTS/COMPANIES. Any help is greatly appreciated.

    For those simply swapping the JDM F22B heads onto a F22ax block with no Delta cam regrinds, etc. If it's physically possible to get a .030" mill on this head, you will be around 9.8:1 compression and so using a P14 (H23) ECU may seem a feasible cheap way to make it work, without spending money on a chipped P06 ECU & tuning. Sidenote: a .020" mill will yield 9.6:1 compression, that may be good enough if .030" is too much.

    Now if you go camshaft regrinds, use a chipped P06 & tuning obviously.

    Also, using indirect calculations I calculated a stock JDM F22B DOHC non-vtec head to have about 47.2 head CC. Not many know or have this info, use it to your advantage.
    i will take this note you post to my advantage i have one laying in my basement if i get some extra $$ i might add this project to my current projects that i am working on.
    thanks

    precisely im trying to do the swap myself..its hard to find them.. you will see the head swap once in a blue moon on e-bay..you gotta get down n dirty with all the honda forums to find em..
    this is definietly something i want...i would modifiy my throttle body cuz i already have an f22a6...and definielty get an aftermarket DC header .. and high flow cat.....
    i would love to do thsi swap..im just wondering about timing issues..and fucking up my pistons :P..
    i cant wait for someone to dyno a f22ax head swap..so we can see the performance gains!...i might have to be the 1st to do it :P
