like the topic says. is there any differences in main or rod bore size and is it interchangeable?

 

F22 crank = H23 crank

they are the same and yes interchangeable with an H22a block 93-97 only. 98+ main bearing size changed.

 

do you mean the 93 - 96 or does it include the 97 year also?

No it includes 97...even though 97 was the first year for the H22A4, they used the exact same crank specs, then in 98, I think it was due to development that had been started once the engineers realized how many preludes spin bearings they beefed up the main bearings from 50mm to 55mm. Check the bearing part no's they are all the same till 1998. I've seen it myself

edit: I'll also add F22 rods and H23 rods are the same...the only reason it's a 2.2 is the 85mm cylinder bore.

 

hmmm........since the F22 and H23 are so similar, does anyone know if the F22 has a problem w/ spinning bearings, like the H23?

Well it has a lower redline (I think) and makes less power so i suppose it's less of an issue.
