If you can't keep a turbo alive, don't own one. A constant supply of oil, and most importantly, a shutdown routine are essential. I let my car idle for between 45 seconds to up to a minute and a half depending upon how I've driven it before shut down. The only time oil stops flowing to the turbo is when you shut it down. Shut if of hot and the oil remaining in the center section will burn and turn into pen 15e. That's what kills turbos. Water cooling the center section helps to a degree, but you still need to follow a shutdown procedure. Also, maintanence is critical. Keep the oil changed, and use the right stuff.
The original IHI in my 88TC lasted 168000 miles. It would've lasted longer, but the car did have two teenage owners before me, and I know the maintanence was lacking. I get to start fresh with a T3 that only has 2000 miles on a quality upgrade/rebuild. This one will be taken care of.
