Ok, I have a Garrett T3/TO4E turbo 57 trim, 63 A/R stage III wheel. This turbo has absolutly no shaft play and has never been boosted above the wg spring (3.79 lbs) it has about 5,000 miles on it, however, the car was only tunned right before I took the turbo off so it rarely saw boost befor the tune. Also, the compressor is jet hot coated sterling silver. If you want pics email me at sandiegosaint@hotmail.com MAKE OFFER,
