It depends on the severity of the damage to the Turbo. It is not common for turbo bearings to damage an engine, since they are not normally made like regular bearings with rollers. It is however common for tiny bits of the rotor to sometime chip off and get into the intake as the . In most cases they are crushed and blown out as they are made of a very thin metal. Again, this usually only occurs when you ignore signs of a failing Turbo and continue to run the engine without repairing the problem. This could result in catastrophic Turbo failure and then mate you could be in some serious problems. Inspect the turbo vanes after you take it out , a little chipping on the edges is is OK

I have a 2003 Grand Prix GTP and when I start the car there is a loud metal-on-metal screaming noise coming from the supercharger area. I assume this is bad news for the supercharger but is it safe to...

Have it towed as the blower has probably lost one or more bearings. If metal shavings enter the cylinders, there could be serious damage there as well. Good luck!
