Turbocharger life on 1993 Volvo 940

I would love to know if anyone has had to replace a turbocharger - what's the longest anyone has gone with the original? I've read that they eventually wear out. Just wondering, thanks! I've got 220K miles and want to learn as much as possible about further care and restoration of this car. Thanks!
