I have civic hb with a h22 engine. Well I have crower stage 3 cams, skunk2 cam gears, skunk2 springs and retainers, H22 type S pistons. And I'm thinking about buying an h23 block and build an h23 vtec and put all those things that I just listed. Or just build my h22.
I'd like to know what would be more relaible and faster.

 

power and reliability all come down to the quality of the build and parts. the h23's displacement would outpower the h22's displacement, assuming they have not been bored/stroked. but i think the h22 is built better to handle power. if you think you can build a h23 vtec without half-assing anything and are precise about every aspect of the build, then i would say go for the h23 vtec.

 

H23 vtec. Just build it "right"

I'm going with this one , at least I did lol.

 

theres already a thread that covers this in rather great detail. the thread starts as a how too but theres much info on h22 Vs. H23vtec.

essentially thou,
h22-prices have gone down for full swaps, more reliable than h23/vtec under daily driving average maintenance

h23vtec-more torque than h22,bit more expensive than h22 swap, you lose a little reliability for a dail driver. the main problem with h23vtec is the bearings in an h23 arent designed to handle the loads brought on by higher rpms which the h22 head is capable of. the redline on an h23 is some 2000rpm less than the h22. as a result people have been spinning bearings all the way up to literaly melting them.

check out the thread, there are some very good, technical arguments both for and against

lol, a link to the thread would help huh

 

H22, it would cost alot more to build a H23VTEC the right way than to just get the H22, which is more capable of higher RPM's with it's crankshaft, you'd have to basically build a H23 from the bottom up to get the same performance and compression ratio. Am I Right?

with the k20 becoming the new "super swap" h22 swap prices have dropped. The h23 will make more torque, but its reliability hasnt been proven yet. If you got roughly 1200.00 pick up a full h22 swap, its cheaper, easier, safer
