i havent had experience buying turbos off ebay but a couple of friends of mine have. 3-7 received good condition turbos. the other 4 however...well thats another story... the turbos were suppose to be brand new but when they received them they had WAAAAYY too much shaft play. They needed rebuilding which would cost them more money. I would probably buy the other parts for the turbo setup off ebay but not the turbo itself. just my .02 cents
