if u really want one ill sell u mine, $100 i used it for all of about 3 minutes, the car didnt boost just idled, as soon as the exhaust housing and exhaust were hot enough, it blew white oil smoke everywhere as the oil seal was already gone and it was leaking oil straight into the exhaust wheel after that drove it anyway for about 2 mins it otherwise worked well and boosted extremely hard at about 4400 on a rb20.
