Turbo failures

How many of you have had turbo failures? What type of turbo was it? Did the vendor help you? If the vendor helped you out, who was the vendor?

I know I've seen quite a few VF22's fail but was trying to see if it was widespread and what venders would support you if you had a problem.

Stock turbo failed at 17k miles. 02 WRX.
17k later and the FP unit is kicking butt.

The absolute primary cause of turbo failure on the WRX, according to my dealership, is a break in a coolant line. Remember, the turbo is BOTH liquid and oil cooled -- and it needs it! If either coolant line gets a crack or falls off, that turbo is toast. There's no other reason for one to fail, unless you've got a manual boost controller and you are hitting 18lbs in first gear.

High boost on VF22

The VF22 and other IHI turbos seem to have issues if run at high boost ( ie 18 psi) on a daily basis.

Some folks have also had "smoking" due to seal problems on them. Not sure if the seal problem is related to thrust bearing problems from high boost on not.

The mitsubishi and Garrett turbos have better thrust bearings / designs available. I'm not aware of a 360 degree thrust bearing upgrade being available for the IHI turbos.
