Damaging a turbo by not priming it is just a way for manufacturers to screw you out of the warranty of a fucked turbo. Not that it causes it, but they can say, "Oh, you mean you didn't do that? Well, we can't cover it." 
Start the car, let it idle for 15 minutes. Shut off and let it cool down all the way. Then start it and idle again for 15 minutes, then go out and put some load on it at different rpms. Oh, and don't think too hard.

haha, that reminds me of the time I was at hotrex's house and I picked up his turbo in his room and I started spinning the shaft and he's like, "dude, don't do that ----, it doesn't have any oil in it. hahahhahahahahahaha

Re: starting for the first time
Who ever is telling you to let a fresh engine idle for fifteen minutes should not be giving you advise. Thats the worse thing you can do . If you have installed new cam(s) you will burn them out. At idle the cam(s) recieve very little oil pressure. You must start the engine, watch for good oil pressure(make sure theres no missing or anything else that doesn't sound right, lifter clack is normal for a bit) then run at 2500rpm for 10 minutes. Have someone watching the engine for any leaks and topping off coolant etc. Then shut engine off, check fluids. If all ok go for a 20 minutes drive but do not stay at a constant speed. Change the oil and filter and go racing. As for turbo break in just get someone to hold the compressor wheel when you first start up and checking for oil pressure then tell them to let go and idle up. Trust me, the turbo will be fine. I work in an engine shop and do this at least 3-4 times a week. You must change the oil right away( no synthetic during break in ) since the rings will have scraped (set in) the cyl. walls smooth. Then change to synthetic if you like. If all good, GO RACE!
