So im real close to buying a jdm head for my h23 block.But just a couple of things crossed my mind a h23 block is obviously a bigger bore than the 2.2 so more fluid will be comming up from the block and then being crammed into the head which is smaller is that a problem, I can get it bored bigger if i need too. Im assuming i will need a new wirring harness for the head and a h22a ecu is that correct. If anyone has the h22 head on the h23 block and will like to share there thoughts about it would be greatly appreciated.

 

Have youu tried searching this topic? I believe there are many, many of them..

 

yes i have tried but have found nothing on the diffrent size on the bores and i figured why not put in the other stuff while im at it.

 

um...how is an 87mm bore different from an 87mm bore?
next time search for h23vtec its all over teh damn place.

ha 'obviously'

h23 and H22 blocks are the same bore.

Displacement has 2 variables: bore and stroke. you now have one eliminated. good luck figuring it out
