What's the difference between H22 and H23 - Honda Prelude Forum

sixiao · 02-13-2003, 12:44 PM

If a header, cam gears, pulleys, and etc. fit on H22a then it should fit all H23 too right? because they're all "H" series. I think they are all same, but some people would say a part like header will only fit on Prelude Vtec, I think that's not right, am I correct? thanks

they are not the same, the bolt pattern on the head is different between the h22 and h23 for the header.

The heads are different. For starters, H22 is VTEC, and H23 is not. The bolt patterns for the header, and the intake manifold are different on each head.

You should do some searching here to find out all this basic information.

Yea, search because this has been covered many many times.

i think all those parts you listed are all different, the i know H23s use the same cam gears as the B Series DOHC motors

header and cam gears are different for sure. H22a and H23 have different timing belts for this reason.
