with proper modification, re drilling ports etc. you can put a DOHC ZC head on it, that's my setup. And most dohc zc parts and a d16a1 are they same, But I would still double check to be sure.

I wouldn't do anything to the D16a1 at all. Its a motor that doesn't easily swap into a 2nd gen CRX. It is more of a 1st gen swap.

I'd go with a B18a1 swap from a 90-91 integra, it's a pretty easy swap, no wiring involved unless you have a DX, and a respectable HP and TQ gain.

Thats just my opinion though.

B series head swap is out.
Keep your current setup and don't waste your time with a head swap on that d16a1.

The problem with swapping in the D16A1 is that the driver's side engine mount is in the wrong spot, so a custom mount needs to be made. For all the work to get it in and running, you'll only gain 10hp.

The DOHC ZC head interchanges with the D16A1 head. The difference between the two lies in the cams and cam gears. Everything else interchanges. The ZC/A1 head only needs to be machined to use on a single cam block because the oil ports don't match up, along with one head bolt.
