I have an 88 mazda rx-7 annivarsary edition. I have noticed that lately my turbo doesn't have that whistling sing to it anymore. Instead of a whistle, it sounds more like a rattling, like my turbo is loose and it is not spinning smoothly, or something like that. It still kicks the boost up high like it used to, but I am worried that it is breaking. Have any of you had this problem? Is my turbo about to blow? I have also noticed that my exaust is making a weezing sound somewhere around the turbo. I thought maybe the exaust was just coming loose, but could it be something else with the turbo?? Thanks to all of you for the help!

I really wouldn't worry about it too much if you are getting the same amount of boost that you were getting before. An easy way to check the bearings in you turbo is to remove the TID and wiggle the turbos shaft and see if it has any play, it should have no play, and should not wiggle at all.
