I used these for 5k miles until my car was vandalized to the point of a total loss. I am currently swapping my engine and everything into a new Z and am getting even bigger turbos, new manifolds, and a bunch of other parts while its out, so I now have these turbos for sale. They have no shaft play at all, and the turbos have been checked and tested by the company that built them (BNR) for any leaks or problems, and have been verified to be in perfect working condition. Please email me if you are interested, have any questions, or would like pictures.
