Ok. where should I start. The F22B came in the JDM prelude Si. Honda produced the H23 for the american market. The F22B is basically the same thing as the h23, but it has 9.2-9.5:1 compression and an 85mm bore. unlike the h23 and h22 that have the 87mm bore. It also has Iron sleeves in it stock. Everything on it is interchangeable with the h23 so...... if you want to bolt an H22 head onto it all you have to do is follow the same procedures as if you were doing an H23VTEC build. Matter of fact here is all that you will need.
write up... not sure but i do know all the parts required.
h22a head 93+(USDM) or 92+ (JDM) with all internals and valve cover
h22a thermostat housing
h22a waterpipe
h22a waterpump
h22a headgasket
h22a lower crank gear
h22a timing belt
h22a headbolts
h22a plug wires
h22a intake manifold (injectors perfered)
h22a header and downpipe
h22a cam gears
h22a top timing belt covers
h22a power steering braket (h23 doesn't line up right)
everything else is easy.. swap out all the parts and sensors from the h23 to the h22a intake manifold.
you can use the h23 powersteering holder but you ned to grind some off the mounting point to clear the head if not it won't bolt up, about 1 inch or so....
eh.. keep the same distributor mounts the same and is fine, but the wires are deeper in the h22a. use the manual tensioner.
replace all the parts listed above, rmove the oilcontrol plug in the block, before putting the head on.
install all the parts, you will need to run other wires and the ecu, but machanically this is it, you cannot use the same waterpump, lower crank gear because the teeth are off and the belt would fail....
anybody attemptin this from a h23 is waisting his time and money.. simpler to go if you allready have an h22a... otherwise will be more expensive the other way...
my own opinion.
and also you need to modify a couple vacuum lines and coolant lines if you keep the non vtec throttlebody because of the extra line.. otherwise do-able....
hope this helps....
As long as you balance the crank and install the H22 oil squirters in, it will last much longer than anybody will think and still be able to rev as high as a stock H22. Hell throw in some h22 type-S pistons and rebush the stock h23 rods and you'll have 11.6:1 compression with a 2156cc Vtec motor. Basically your planning on making a stroker kit out of stock parts. If you done this, me and you will be in a race to see who finishes there's first. If anyone doubts what I'm saying go here and work the numbers out yourself for extra confirmation:

Not only have I done the numbers but I've seen it done. Trust me it works as long as you do it right the first time. Good luck and have fun.
