I'm planning on looking for a 2005 GTP at a junkyard. I would like to take the supercharger out of it and stick it in my GT. Is that risky? I wouldn't want to buy a used supercharger that's been sitting for 3 years and starting to rust. What are signs that a used supercharger is bad and shouldn't be bought? What's a reasonable price for a junkyard supercharger?
