It never did get approved. My understanding is that CARB wouldn't approve it because the E-Manage can be reprogrammed with relative ease.
So the answer to the original question is no. The only legal major power upgrade would be to use a different engine that legal in the car. Basically any non-truck engine in RWD layout, with all OE smog equipment and from a CA smog car if you have a CA smog car and from the same model year or newer.SO basically, if you could get a Z06 Corvett motor and transmission to fit(however diffidult it would be to get the transmission to fit in the back), you could 'easily' have a legal 400+ HP car. A VQ could be a great motor for this, but may have to ditch the OE cats for clearance issues and may not be able to pass through a referee. A 2JZ-GTE would be fun and could be legal if you choose carefully.
