Alright I've heard a lot of OPINIONS from people about what will pass and what won't pass CARB smog refs. We all know you have to have an engine from same year or newer, it has to have been available in the USDM, and you have to maintain all the original emission equipment. So if all you did was a straight swap with no mods, it should pass with flying colors. But what about mods: intakes, headers, exhaust, cams, ecus, compression, etc..... What I want to know is what setup have people actually got passed a ref? (First hand experiences only, please...save the urban legends for the camp fire.) I'll go first... I have an 89 CRX Si with MSD ignition, JG throttle body, stage 1 cam, DC header, and an exhaust. It's never actually had to go to a ref, but its passed the 'smog only inspection' every 2 years for the last 6 years. The only thing I have to do is set the timing back to within the factory limits before the test.
