now i know this is always talked about. so i did search and i did get info, and i did post on another thread but havent got an answer. sorry if anybody gets mad at this..but i was reading the begining of a post that was 13 pages long and then skipped a lot of it, so i dont know if it was already talked about. So heres my question. Should i build up my motor to h23 vtec or just get the h22 swap? is there that much of a difference in the two? throughout the post everyone is goin back and forth between the two, and i havent seen a definite answer. I would love to do the h23 vtec, but if its going to cost more than an h22 swap, and not put up the same or better numbers, i dont know if it is worth it. So you tell me, h23 vtec or h22. i need to do one of these soon, so help me out a little bit. thanks! and feel free to move this if it is in the wrong place.

 

I would say h22 swap is much easier and les costly. Either way, you have to find an h22 head and h23 bottom end(which apparently you already have) and combine them. The h23 vtec is supposed to have a better powerband overall but not quite as reliable as the h22. I would just buy an h22 and build that for turbo or na, it would be much more efficient.

 

If you are willing to spend the money to do it right, go the H23 route. If not, do the straight H22 swap.

Honestly, the .1L displacement isn't going to make THAT much of a difference.

If i was going to do a hybrid, I would mate the F23 crank to the H22.

 

Gonna agree with andyD on this. The h23 block helps to retain that low end tq but it's not quite worth the general unreliability of it.

Spend the same amount of money to swap an h22 and go with cams/valvetrain upgrade.

 

I am in the middle of making mine H23vtec, started with H23. Honestly, if it weren't for the "novelty" of having it, going just to an H22 would be a lot less hassle. It might have a higher initial cost to get the H22 motor+tranny, but it honestly works out to be about the same. Besides the head itself and intake manifold, I bought all the other parts that needed switched out new from Honda.
