As long as you use the correct oil, change regularly, and don't push the engine/turbo hard before it's warmed up properly, you should be fine. Keep in mind there are "mild" turbos that only put out a few psi(Volvo?) vs some highly compressing ones at 20+ psi. Aside from poor design like the ones you may have seen back in the 80's, today's turbos are far more reliable. I would expect you'll have to use premium fuel on most, if not all turbo engines these days if the extra fuel expense is an issue and likely synthetic oil(although many cars use synth these days anyway).

I don't know if car companies these days recommend this or not re turbo engines, but in my owners manual of the '83 930 I had, Porsche recommended you drive the car for a few minutes to get the oil temperature up, then open up the throttle to activate/clear the wastegate...I think it was to clear any condensation that may have settled there.
