i have the stock turbo sitting in the garage , the compressor wheel is chewd-up and the compressor housing has some gouges in it, because the seal went. My questions are can this be rebuilt ? Is it worth it to rebuild? Can i upgrade it to a bigger compressor? where do I get the parts? And of course how much about? Seems a waste just to let it sit, I ve already replaced it with a Ta-49 on the car so this is just for experience.
