Breaking in a new 13b

What's the proper procedure since putting 1000 miles on it under 4k RPM is not realistic?

New rotor bearings, among many other internal parts, not to mention a new ECU with only a base map.

Do I start it, run for 30 mins at low idle, change oil, idle under 4k RPM all day outside the shop and change the oil every few hours? 10w-40 for break in and then go to 20w-50? Rent the dyno for a day and run it under low RPM load? :017:
 
My experience with the rotaries is that it doesn't need the same measure of break in time as a piston motor. I used to have the shop run it on a dyno for an hour or as long as they were willing. Get some baseline pulls. Then ran it easy for one practice session, changed the oil and looked for filings in the oil. No filings - ran the piss out of it.

Curious to see what the Flatout guys say to do...
 
If the bearing clearance is properly set when built then, just as Joeg said, put it together and run it. It's what I do with 500+ hp turbo engines just like I do with a 170 hp IT engine.
