so my turbo has been making a loud noise for a few days, so i did my timing belt yesterday and while everything is apart i checked the shaft play in my turbo and i moves quiet a bit. anyways i'v come to the conclusion that my turbo is blown and my question is what is going to happen when this thing dies completly? will the car not run? will the turbo be rebuildable, also can i put a gt28rs with out a tune for a little bit? thanks in advanced for your input.
