from what i know, 33n1 pistons, n1 oil pump, cams and the rest is a bit unknown untill i pull it down.
i'd probably want to go with another oil pump to jun etc. and hope that there are baffles etc in the motor already.
i'm thinking of doing rods, pistons, oil pump, head and might modifiy the sump at my friends work to hold some moar oil.
