I have owned several factory turbocharged cars, 2 Audis and a Turbo GP. From what I have seen, the factories, espaecially Audi, went to all sorts of gyrations to make these engines as reliable as a normal engine. This included an oil filter and oil cooler just for the turbo, a separate fan to blow air over the injectors to keep them cool because of the additional under hood heat caused by the turbo, a separate electric water pump to cool the turbo bearings, and an after run cooling set up which turned the turbo water pump and cooling fans on after the engine was shut down in order to keep the turbo bearings from cooking the lube oil. I really don't see too many tuners going to all this work to keep the turbo reliable. So the other solution is a lot of maintance, whic can be a real pain in the arse. Personally I prefer a screw type supecharger, such as the Whipple. These are very efficient, more than a centrifugal unit, provide boost from idle to red line, requre a lot less plumbing than a turbo, or even a centrifugal, and don't heat up the air as much as a roots or centrifugal unit.
