hey guys! just bought a mid range KM 86 VL n/a. the oil pump is a bit lazy on start up both warm and cold but once its going theres no issue even up near redline. soon im looking at rebuilding the RB30 and keeping it n/a as i feel no need for a turbo.. wanna do something a little different. will a RB26 oil pump fit onto the RB30? or what oil pump would you suggest? was looking at a high volume pump. will i need a bigger sump? i know it will need a crank collar but im curious on the fitment. Some original photos have not been recovered yet.
