Hitting 300rwhp N/A for a 2v is not a long shop, just costly. lol.
Full bolt ons + full exhaust + cams should get you around that ball park.
Mike's car bid it, along with many, many more New Edge 2vs.
You need to ask your self though, is the cost of the cams, plus the install, and plus the tune going to be worth it? Especially if you want to blow your motor in the future.
