I know all about what it takes to be smog legal and to get a swap BAR'd. My questions have to do with what smog techs look at as far as the engine is concerned. I know they look at all your emissions equipment but do they look at the engine code itself? I got a DB1 and I want to know if they are looking for the B18a1 code or are they just looking to see if it's a B18. That being said, would they see B18c and say 'oh ok, it still has the B18 engine' Also, would it be ok to see a smaller engine in it? Ideally I want to get the XSi B16 swap from hmotors so technically, from a smog point of view, a smaller engine would be better smog wise lol? I'm not worried about passing the sniffer as that's no problem to me. It's getting them to just go forth with the smog test is what i'm concerned with. I've called a few smog places by asking questions that I thought would lead them to answering my questions without directly asking them in hopes not to tip them off about the engine codes but I guess I didn't ask the right questions because I got no answers lol. One guy started talking about 5 cylinder engines out of no where WTF? I've read all the info I could find on the net and in the reference section on here but to nothing answered my questions. So if you got any info, let's hear it. Oh and no he said she said BS, I need legit info. Thanks.
