Looking for Ideas - Running GM Computer on Toyota

Hello everyone,

I apologize in advance if this sounds like a ridiculous hair-brained idea, but I wanted your guys input on it.

I live in a state where they require an OBD2 scan on cars newer than 25 years old to pass emissions. My question is (without discussing the legality of it, this is just an idea) do you think with the expansive tuning capabilities of the HPTuners could you run a 2JZ on some sort of GM (maybe 3800) ECU? I know it would take some wiring know-how and swapping out basically every sensor in the car (not new to me) but I'm not sure if there would be a hang-up elsewhere on it.

Not likely.
