As long as you treat it right. Let oil get to it before you take off, and allow it to idle a minute or two before shut down. If you shut down on a hot turbo, over time you will "coke" the bearings with burnt oil and eventually jam the turbo.

The reason diesel turbos last longer: diesel exhaust hits the turbo at around 900 degrees under heavy load, and normally 600 degrees. Gas?? lets try 1500 degrees, maybe 1300 under normal loads. Gas engines still have burning fuel when it leaves the cylinder. Its a wonder that they last at all.
(I know, the nit pickers are about to start, I got my diesel info from a Ford truck with a pyrometer, and gas info from airplanes with EGT and T I T probes.)
