If you prime the motor it will prime the turbo, I prefer to do it since they have limited oil on the bushing/bearing when it is assembled.
Garrett actually has a break in procedure for new turbo's atleast it was on the tag for my GT42 76mm...for the most part is is just a bunch of checks to make sure you have no leaks, or hard issues, and I have had some tell me limit boost for the first 100-200 miles, they do suggest priming or filling the turbo prior to start-up.
