best way to prime the turbo is leave the oil return pipe off the bottom i know its not easiest to leave off then fit after. disconnect the injector wiring loom and then wind the car over letting the oil flow about, this will make its way up to the head aswell and fill the vvt side up also. let the oil run thru the turbo and when you can see there is enough oil coming thru the oil return you can reconnect return and the injectors and fire it up. then let it idle for a few mins. turn off and check oil, water levels then should be OK to run the water up and then road test
