150,000 miles on a h23. Upgrade the h23 or swap for a Jdm H22? Just want to get some opinions. They come out to about the same horse power. But the H22 is about $1,000 more.

while i like the sounds of an H23 powered up to H22 specs(or better). i would probably go with the H22 just for the ease of the whole thing. a unmodded H22 is going to be more reliable than say an H23 with high compression pistons, lumpy cams, etc..

I say you stick with the H23A, save the money, and put it into a turbo. You could replace all of your stock internals (most of which are pretty shot after 150k) with fancy internals and do it right the first time, that way you wont have perfectly good H22A parts sitting around. Keep in mind this is only if you would want to to go F/I.

If you are sticking with Naturally Aspirated, then an H22A VTEC would probably your best bet. You could always get an H22A VTEC head and put it on your 2.3 litre and have a H23A VTEC? Just throwing out some ideas.

I was told that making a H23 vtec hybrid. Is more trouble than it is worth. to mant holes to drill. Something to that degree. Has anyone do that?
