I'm in.
Missed the OP.
One of the cars I worked on this year was an F-body with an aluminum engine of LS1-based architecture but well north of 400ci, being force fed by two small T3 turbos. Made enough power to lunge the full-interior, full power everything, road-course style suspension (BEEEEEG brakes/tires) F-bod to low 10s and very high 130s on street rubber, so extrapolate that how you will. Don't forget to add some extra pounds for the rollbar.
Anyway, point of story: It still had a pair of converters on it, still used the factory PCM, and was OBD-II compliant, which is necessary if you want to register your car in the parts of Ohio that aren't cornfield.
That's an example of a smog-legal engine that makes well over double its stock output. I have little doubt that the Subaru electronics could be massaged for similar compliance if anybody cared. Wait - I know it's possible, I've worked on one example of such. EJ257 block swapped WRX with plenty of bolt-ons, still passed the scantool test. That one only made 270-odd wheel horsepower, though.
