The car I just bought had an ebay turbo and the reason the guy sold it is because he blew the engine within 3 days of installing it. Don't get an ebay turbo unless you really feel like buying a new engine when yours blows.

 

Yeah alotta people are giving mixed emotions about the ebay turbos. I think it matters how you install it and how hard you ride it before you break it in because these turbos arn't tested from the factory and so are un-used. So like anything new you have to go easy on it for a bit before you can start pushing it.
