thats the funny thing about the ceremic turbine wheel ball bearing turboes... they can only handle around 14 psi and to rebuild one.. just a standard rebuild they are only around 200 dollars cheaper then buying a new one so it wouldnt be a good idea to buy one if it is a mod from non turbo to going turbo unless you are prepared to dish out the dollars for a new steel turbine wheel straight up if you are gonan run big boost
