Corrections for all of you...
I've seen more proof to show that there WAS a JDM SOHC ZC VTEC engine than not- but no, it wasn't available in the USA. Supposedly the SOHC ZC VTEC is identical to the D16Z6. I've never seen one in person, but I'm inclined to believe it really exists.
Honda liked to stamp "ZC" on their highest performing D series engines, so there are quite a few that are marked "ZC"- including the DOHC ZC that everyone knows so well.
Fact: There IS a JDM SOHC ZC (non-VTEC) from the 88-91 Civic. I own one. Look at my web site for pictures if you don't believe me... and if you don't know how to navigate to it, please don't bother using the internet ever again. The engine is identical to the USDM D16A6 except for the camshaft. Not ALL ZC engines are DOHC, and not all are non-VTEC (again, not 100% sure, but pretty sure).
Hope that clears things up for people.
Dancomer- if you only have one of each of these engines on hand and you're trying to sell them, I'll let you continue this post. That was my understanding when you first posted this up. If you're sourcing multiple engines of each from another supplier, I strongly suggest (read that as require) that you talk to B about becoming a registered vendor before selling these on the board.
