CRX - Smaller, same motor specs
Civic HB - Bigger, same motors pecs
The 88-91 CRX/Civic Si's don't come with d16z6 they come with d16a6 motor. The D16z6 are found in the 92-95 Civic HB Si or EX coupe and the 92n up Del Sol Si vtec (not DOHC model). Wait I think the ex coupe and del sol are the d16y8 motors. Either way, almost identical specs on the z6 and y8 motors. Hope this helped.
