OBD1 VS OBD2 & Smogging - HondaClub.com

goeclectic · 01-30-2007, 12:28 PM

I have what my shop and I understand to be a '95 B18C gsr engine swapped into a CRX. The info we have says it is an OBD1. The local smog referee thinks it is an OBD2.

Any information out there to give me a firm answer? Thanks!
