lets face it, ur not going to be easy on this motor, and ur going to see it bouncing off the limiter a fair few times. uve read the oil control thread right? rb's spin bearings because of the lack of oil in the sump, that means its up in the head.
restricting the flow to the head, and running an external drain from the back of the head, will help get all that excess oil back down into the sump, where its meant to be.
also, the n1 pumps flow more than the std pumps, but at the same pressure.
