Where do I find the engine code? What is the difference between a F22 and H22?

 

I believe the F22 is non VTEC, if it is VTEC it's a much different setup then the H22, also guessing I would say compression is lower as well.

 

thatpreuldeguy you are right...good guess
the engine code is on the block right above the hole where you can see the flywheel and clutch
the f22 is sohc both vtec and non vtec the one that comes in the cl is vtec.
the compression is 8.5:1

the h22 is dohc vtec comes in the prelude and some jdm accords
compression 10.0:1 and 10.6:1 depending where it is from (usdm or jdm)
