I wouldn't touch it with a 10 ft pole. 1M's are seeing around 325-330 rwhp stock and 350-360 rwhp tuned. This one would theoretically be getting 30-40 more hp then the others. Whether it's a weekend warrior, daily driver, or a track car it's pushing things too far in my opinion.
Since you are in Hollywood why don't you get in contact with Randy @ Epic MotorSports in Miami? He's someone that I highly recommend.
