I am recently from CA, and a legal swap would be through the state referee. If the motor comes out clean and passes strict emission (no JDM) they put a state certify sticker on the passenger side door with motor infos. Is it the same over here? And those of U who have a USDM B18c1 or B16A swap on a civic, is it simple to pass emission? I am asking because I am thinking of doing a b18c1 swap on my eg8.
