Keep a spare turbo around.

Just make sure you change the oil frequently (no more than 5000 miles) and use a good full-synthetic oil. Turbochargers are wear items and they need clean oil to last. The synthetic oil will stand up to the high temperatures, while conventional or even semi-synthetic can cause coking and turbocharger failure.

It's a good idea to let the car idle a little while before turning the engine off to let the turbocharger spin down and cool down a bit, especially after high speed driving. (It's not quite as necessary as it used to be before the advent of water-cooled turbochargers but it's still a good thing to do.)

Take it easy on that thing if you want it to last a while. Unlike some older turbocharged engines that were heavily built to withstand the additional pressure of the turbo (and did not include GDI), Ford's "Ecoboost" engines are light-duty mills that are not known for longevity.

Sprinkle it with holy water?
