Call Garrett and ask them why they provide a cooling jacket for this turbo.

I'll save you the call (because I already asked them this question). It's there to provide cooling to the turbo shaft when the average person shuts down the engine before the turbo has had time to cool at idle. It has nothing to do with cooling during use - the oil supplied to the bearings is ample to lubricate and cool them during use. I've used my turbo without supplemental cooling for more than 5 years and it's still going strong - but I always let the motor idle a couple minutes before shutting the engine off.
