2000 to 2500 rpm for 10mins.

I was just told not to let the car idle for too long in the first few hours. I'd suggest the same go's for that fresh motor as well.

NEVER LET THE CAR IDLE!

Start the engine and vary revs from 2-2500rpm as Sean suggested. Get someone to check for leaks of any kind while you do this or check your self while someone else does the revs. Just go up and down up and down. Do that for about 10 minutes until you are satisfied that it will drive safely. Make sure the car doesn't blow any black smoke and the oil pressure is good before you go. When you start it, it should have between 80-110psi cold and once warm expect between 30-40psi. Monitor the oil gauge at all times. Go for a drive and load it up on hills ie. 5th gear at 1500-2000rpm and try to climb the hill. On the downhills, put it in 3rd an decel. Get the engine to work on the downslope as the vacuum it creates will pull the rings against the bore. When you come to a stop at lights, free rev in neutral every 30 seconds or so, just blip the throttle to avoid long periods of idle.

You will need to drive like this for at least the first 250kms

Oops, didn't read the rebuilt engine bit lol. Yeah load it up to bed in the rings, hills are good... I went as far as disconnecting the wastegate actuators from the arms so I had no boost.
