The "blacktop" ZC that was in the 88ish Integras actually has ZC stamped on the block. It is easily distinguishable from the CRX ZC of the same years because the valve cover bolts are closer in towards the spark plug wires like a USDM 86-89 Integra motor (which I also noticed you made some typo there about it being a D16A8 or D16A9, the USDM one used the engine code D16A1 for those years (even though there were pretty big changes between 87 and 88).
The D16A8 and D16A9 were used in CRXs in other countries
These two engines are not interchangeable with one another and have different engine mounts. The Integra’s driver’s side mount is located near the front of the engine while the JDM ZC’s engine mount is closer to the timing belt cover. It is also worth noting that the valve covers and intake manifolds are also slightly different.
and alas your answers were only clicks away... from swap articles...

no the zc is not the d16a1... the mounts are different... just ante up and get the real deal from japan... oh and you need a std or dx harness to make the swap as easy as possible...
