From what I know about smog legality here in CA, if you install an engine from OBD2 car into a car that doesn't have it, you need to transfer the entire OBD2 system.
Basically the engine (including emissions system) needs to function exactly as it did in the original car which includes the OBD2 system. You must run the stock ECU. Good luck with that.
It was much easier in the pre-OBD2 days since car electronics weren't nearly as integrated. The engine swap I did in my early 90's Accord was plug-and-play and the guy I sold it to had no trouble getting BAR sticker for the swap.
EDIT: And in Cali your car gets sniffed and visual inspection no matter what. And don't forget we have dynos for smog checks as well. The only way to avoid the rollers is by having an AWD car.
Well you can't run a 1MZ on a 5SFE computer or harness... you HAVE to use the correct ECU for the engine.
An engine swap nearly always includes the complete electrical harness and computer and sensors, so it retains OBD2 and all original function.
