is it possible?

 

f22 = sohc
h23a = dohc

With money, anything is possible. But in reality, I doubt this hybrid is.

 

the h22a head has been put on the f22 block before, but it required alot of machine work and it makes no sense $ wise

 

Don't you have to heavily modify the coolant jackets since the majority of them do not line up with each other?

yup

someone on superhonda had it done a few years ago, i think it blew up after 5k mile or so

 

does any one else have any more info on this

 

I think it's Prelittlelude has a writeup on how his is going. He put the H22 head on an F22 block.

The H22 and H23 share most of the passages for coolant and oil in the head, aside for the one for VTEC that you remove the oil control orifice for in an H23 VTEC. Reasoning would suggest that the H23 should go on the F22 block about as easily as the H22.

I am seriously considering trying it b/c i have my spare H23 head sittin around, and I'm sure I can pick up an F22 block for cheap.

 

yup h23 head on a f22 is even easier than the h22,

there is the link to my project

for the h23 head you don't need to plug any oil holes, and i think the f22 or even h23 water pipe will work just fine without need for modification.

if you need more info let me know, its pretty easy
