Got my GT6152 turbo in the mail and (with the help of Paul, pacecarta) removed the stock turbo and put on the new turbo yesterday. First thing we noticed with the old stock turbo was the huge in and out shaft play on the turbo. It was between 3 and 4 mm! There was very little side to side play though. Paul took the turbo apart to see what the fins looked like. There was so much play that the fins rubbed against the housing and ate away the housing too.
Here are some pics and a movie of the turbo. I ran 3 straight 12.4s last time at the track with this turbo in November! Good god, think what I would have been running with a good stock turbo. No wonder it didn't spool well with the tight converter.
