there is an obd 0 zc and an obd 1 zc. the obd 0 zc came in 88-91 crx sis in japan. here are the specs on the zc. its very similar to the D16A8/9 found in us integras. not a bad deal for $600 or so. bolting the engine into a crx with an si transmission makes for a quick little car. my dad did this swap and hes happy. in my opinion its better than a mini-me or swapping in a single overhead cam d16z. dohc engines have more potential.
