Check the back of Sport Compact Car magazine or especially "Turbo Imports" magazine (something like that, I forget the exact name). There are two places that are really well know, one is Turbocity (turbocity.com), and the other is Turbonetics - and there are many more I am sure. I think turbonetics advertises a rebuild with a 24 hour turnaround time. Price might be around $400. Give them a call, because I know they work with a brands of turbos.
