Ok my friend has a Sc300 He put a thicker headgasket on it and turboed it..It hauls ass plain and simple..He also has a Supra with the twins still on it And his Lexus is WAYYYYYY faster than his Supra..He also has a bottle on the Lexus and it runs just fine no problems..I'm not sure on his hp but he runs 11's.He told me that they are basicly the same motor..I'll see if I can get him to post.
