I emailed the guy he doesn't know too much about it but he told me his kid bought the accord with it already on and the car had 44,000 miles on it.He has no idea how long it had been on it.He used it for a while, I think he said december, when his son blew a piston ...I was interested in getting a turbo kit but I don't know it does look so damn beat though I rather spend some more and get it from someone who seems to have a clue.
