01 Millenia Supercharger

Hey guys. I have a question I hope somebody here can help me. I bought my brother an 01 Millenia S for his first car. Thing is this car turned out to be crap and I'm in over 6 grand and in huge debt. The supercharger turned out to be not functioning well so I replaced it with another one. I have the old part which seems to be in good condition, no cracks noises or anything, the dealer just said it was bad. I was wondering if there is a company I can sell the old part to. Maybe a company who rebuilds these things. Any feedback is appreciated.

Thanks
