Anything with turbos can be a maintenance nightmare if not used properly but
if used properly they will last a long time. Don't matter what the
turbocharger is installed on either. My neighbor has a turbo on his truck
and he is running in to problems with it because he don't know how to
properly turn it off. He then wonders why his Bering's have gone out in 6
month's surprized that he got that out of them.

The company I worked for had a P Navajo and I had about 100 hours in it.
It
was a great airplane to fly but the maintenance bills were very high. It's
been too many years to remember many specifics but I seem to remember that
it went through a lot of turbochargers. And alternators. And the Janitrol
heater was problematic. The owner used to say that he could lay in bed at
night and imagine that he could hear parts falling off of that airplane.
The real drawback, however, as I recall, was the EXTREMELY marginal single
engine performance. One of our company pilots described and engine out in
the P as a religious experience.
