Um, its a FEDERAL LAW. As in, mandated by the Federal Government. You can't put an engine from a car that is older than the model year you are transplanting it into. Period.
SR20s and basically all other JDM swaps are illegal, why you ask? Well, let me answer it for you. : ) Because they pollute more than USDM engines...no, that can't be it. Oh, maybe its the fact that its a JDM, as in, Japanese Domestic Markets engine rather than a USDM engine, so it isn't approved by the DOT and EPA. You could have the cleanest engine in the world, and if it isn't DOT or EPA certified, it isn't street legal. : ) People just ignore that whole illegality thing, no matter what state you're in. The only way to get caught is if you have emissions testing though. : )
As far as the no cat thing, its because its pre 76, Cats weren't required then, so you don't need to meet any emissions standards because there were no standards.
