Hi, I've had my VG30DETT rebuilt and just finished putting it back into the car, connecting all the hoses, wires, piping etc and was wondering if anyone on the forum could steer me in the right direction as to the best process for breaking in a rebuilt engine? Is this something I can do myself, or will I need to take the car to a shop to be run on a dyno? If anyone has gone through the process before I'd be happy to hear what you did and what you didn't do or regret not having done etc. This is my first time doing this with any sort of engine, so any advice would be greatly appreciated. Having a look on the net has given me a great deal of mixed results, some places saying to break it in without boost, some saying to break it in hard, some say gentle.. It's pretty confusing and I don't want to screw up many hours and $$$ worth of hard work I've put in.
