Ok .. good list.

Hah!
I gotta admit, it's not so much that I was thinking turbo engines didn't need any attention, but I was not really taking into account the idea that you could really ignore lots of that stuff on naturally aspirated engines
A lot of those items are much less likely to be a problem on modern, well designed turbo vehicles I would think. How often do wastegates really need adjustment? How often would a modern, stock turbo car actually cause hood/firewall paint damage due to excess heat?
Fair point about coolant maintenance, higher quality fluids, and having the extra piping and intercooler to inspect. However plenty of non-turbo cars have components with extra piping (e.g. oil coolers) or just poorly laid out mechanicals that can lead to problems too.
Aside from shorter maintenance intervals (oil, spark plugs) I'm just not convinced that the "average" driver of a turbo vehicle (including the millions of turbo diesels on the roads in addition to the various gas turbo cars that have been around for years) really does much more to keep their vehicles running. Maybe they do suffer earlier failures, I don't know.
