my friend had a 4th gen that had 450 whp. i know people will call it bs but people who are really into racing probably know him. he hangs around with ed bergenholtz and seve leone etc. he had a toally built h23 vtec with a turbo and it was street legal. he doesn't really do 1/4 mi runs because he can't put the power down but he did alot of scca racing.
