I was thinking about a turbo j-spec clip for my n/a mr2 and I was wondering if it would pass maryland emissions. If so is there a company near maryland that sells them and for how much

The Japanese emission standards are tighter than the U.S. but emission controls are totally different. Japanese engines do not have EGRs. Usually a Japanese engine can be retrofitted with these U.S. smog devices, but on some engines, a U.S. cylinder head is needed. The Japanese ECUs are programmed for better fuel (103 octane) with a more aggressive fuel and ignition curve, but they can be used here. This is why some Japanese spec engines have higher compression and about 10-15% more horsepower, compared to U.S. engines.
