Alright i know they are rare as hell, but i got cut a good price on an h23 vtec, the accord sir wagon ones. Not an h22 head on an h23 bottom end. My question is to those of you with h23 vtec's, do stock h22 parts work for those things? Cause for the most part arent the h23 vtec's just h22 heads with h23 bottom, but just came from the factory that way?

 

stock h22 tune up parts will work

If I remember correctly, the only difference is the additional stroke to make it a 2.3L (95mm vs 90mm on an H22a).

So yes, everything external should bolt up fine.

 

there are plenty of threads with this info already

 

sorry i searched but didnt come up with much other then h22 heads on h23 bottom ends.

 

another quick question while the thread is open , what ecu will these things run on? the ecu they come with is for an automatic... standard h22 p13 work?

 

Would work if you convert it to OBD1.

 

p28/p72 + tuning will do you good.
