Trying to figure out specs on my motor swapped 1991 civic since hatch
 

I keep looking everywhere to find the specs for this thing. It has a zc motor and it says 16 valve on the valve cover and we think it from 1989. That's all we can find out, https://cimg8.ibsrv.net/gimg/hondafo...034d0fd55c.jpg

welcome to the forum. the engine id can be located on the exhaust side, left side of the manifold where the block meets the head.

We've tried it an nothing comes up

try calling an automotive shop that you trust and have work done and ask them to see if they might be able to find it for you,
