I remember one my friends luckily owned a Toyota Supra turbo back in college, and he had a turbo timer installed (which allows the engine to idle for 1-2 minutes after turning it off, allowing you to go ahead and shut the door and go into the house, store, etc.).

More and more cars are putting turbos on 4 cylinders, including the cars I am looking at. Even SUVs and trucks are doing work duty with 4 cylinder turbos rather than 6 or 8 cylinders as I'm used to. Do today's turbo engines need idling for 1 minute after a trip? I don't see anyone install turbo timers anymore.

I'm asking because I need all my cars to make it to 200k miles with minimal concerns.

IMHO, no. Most turbo engines today are not under enough stress to require the cool down. I just traded in a 10YO VW 1.8T with 135K miles on and never once let my engine cool before shutting down. The engine operated perfectly.

Now if you drive everyday at 8-10/10ths and slide sideways into your parking space, you may want to consider idling for a minute or so before shutdown.

The turbocharger itself should last that long today, providing it's attached to a car that goes 200k. Today's turbos are built using better bearings, and have the help of better cooling and oil too. It's still not smart to run the engine hard right after starting or immediately before shutting it off, but if you just drive normally, the turbo will last a long time.

Modern synthetic oils and turbocharger design have largely rendered this practice obsolete and unnecessary.

If the turbo is also water cooled I wouldn't worry about it.

While I don't know for sure I am guessing turbos in econobox cars are also water cooled.

I'm pushing 300k miles on my 2001 Jetta (turbo diesel) and haven't touched the thing. I had to clean the intake when I bought it at 80k, but made computer adjustments to prevent that from happening again. The turbo is fine, and I do 20k mile oil change intervals too... so it's not like I baby the thing. I simply don't hammer on the engine the last few minutes of driving. Did the same thing in my 1986 Porsche 944 Turbo, thus no need for a turbo timer.

Most 4 cylinder cars with a factory turbo aren't made for "performance". The turbo helps get better gas mileage. I have a 2013 Dodge Dart with a 1.4L Turbo. It's slow as can be, but I get an average of 36mpg (combined city/highway). Therefor, no turbo timer is needed

^^^Why they put a turbo on it. You get good mileage because the engine is tiny.

It's the opposite. The turbo is designed to provide more power when needed on a smaller engine. It's the smaller engine that gives the better mpg.
