i have a complete h22 head for sale if you're interested... but h23vtec is not like an ls\vtec....Originally Posted by Farrow2005
h23vtec you need, h22 head, h22 head gasket, h22 water pump, h22 timing gear that goes on the crank, remove the oil orifice on the h23 block, and you need the h22 water neck pipe. no need to drill and tap the head and block..... everything is plumbed already.. the h22 and h23 block is the same block except the h23 does not have oil squirters installed, and of course the H23A1 engraving
are you asking about a build or a swap? if its a swap, its like dropping a b-series into a civic but requires custom mounts and cutting the shifter tunnel to fit the h22 shifter assembly. unless you want to do the h2b then that's another story.
