The crankshaft of my 93 Si must be replaced.
Can I put H22A1 crankshaft on my H23A1 block?
Is it identical? I heard that Honda has produced various thickness main bearings for the clearence.

My baby has too long idling... Help me. I'm serious.

Really depends on your automotive knowledge and need for reliability. The H23 VTEC takes alot of know how and tuning ability/ The H22 is a drop in, plug and play situation. Up to you. Good Luck

This is a very old thread.

The general consesus is that the h23a VTEC has the advantage of a slighter greater displacement. Over half the people who have done the frankenstein claim it's not reliable, and the other claim that it is. Like crj_lll said above, technical know-how is the most important thing it.
