Rebuild kits for Garrett turbos are actually cheap as hell...assuming that the compressor blade didn't come into contact with the housing...

You can buy prerebuilt cartridges that only require the dissasembly of the turbo...then slapping it back together...best part is, it's prebalanced!

Only the seals and bearings kits run around 30 bucks...so I could imagine it possible to pick up a shot core and rebuild it...but 100 dollars is what some people would pay for a non reman core.
