The turbos are water and oil cooled. They should be pretty reliable.

^^What he said. Also, make sure you keep up w/ standard maintenance so your turbo last longer (i.e. oil changes and coolant changes at the standard intervals).

someone here, "Wolf", has 94K miles on an MY04 XT. You should ask him how everything is holding up.

he posted in the mileage thread...

I'm on my third Subaru with a turbo (2 Imprezas and now a Forester). The turbo has never been a problem. Just make sure that you change the oil as recommended using quality oil, don't hit boost before the oil is warmed up( some time after the water!) and let it cool after you've had it on boost - so no 90mph to the drive and then switch off!
Advice would be to fit a boost gauge and an oil temp gauge for real peace of mind but I would say that the turbo is good for a long life if treated properly.
Treat it badly and it can be your banks best friend;-)

Yeah, I had a problem with my stock turbo from the day one ... NOT BIG ENOUGH. :grin: But I recently fixed it via an upgrade to 16G.

That's funny, my 16g had the same failure my 13T had.. not big enough.. =P

But really, the turbos are pretty reliable as long as the oil and coolant in the car is good. If the turbo has never been abused they would last quite a long time.

Having owned 11 turbo vehicles I can tell you that I have yet to experience a "turbo" specific failure problem. My Syclone had 73k miles on it when I blew the engine up, and I took the turbo in for inspection at a turbo shop. The prognosis was that the turbo was in great shape, and the bearings and seals were both fine.

As a previous Audi S4 owner (twice) I know that the early cars had some compressor impellar failures that weren't pretty. Other than that most of the car makers engineer a lot of durability into contemporary turbo vehicles. Think about all of the VW, Subaru, Mitsubishi, and Volvo turbo engined cars running around the streets. I am certain that most of the turbo-related maintenance problems are due to maintenance neglect, or the owner not properly managing warm-up and cool-down.

I've had a high mileage TD05-14b turbine housing fail and begin to affect the turbine wheel. Those turbine housing failures are common on 1G DSM's around 10 years/100k or so miles.

Cold side never missed a beat but the turbine was starting to rub on the interior heat shield. The wastegate hole was totally cracked and eroded. It couldn't hold more than 7-8 psi with wastegate disconnected from vacuum(shut.)
