Hey i currently have a H23 in my 92 prelude SI and im going to be getting my hands on a H22 very soon, I have been hearing about just making my H23 Vtec, Some have told me to put the H22 head on the H23 block and my friend told me that i should just put the H23 cranks and rods in the H22. What do you guys think would be my best bet in this situation?

If you had the h22, why in the hell would you want to put the h23 bottom end in, im not even sure if its possible. Just get a JDM h22.

Yes, it's entirely possible, but if you have the entire JDM H22, just put that in. The Frankenstein engine is a risky thing to do, many experience idle problems, among other things. Just swap the engine.
