At this point I plan to offer all plumbing to run this kit I would like to offer oil pans on an exchange basis for turbo oil drain back, I still need more feedback to see what the majority wants. It may come down to only 3 people want a header /manifold and that may be it for awhile. As for Oil pumps your oil pump will do the job nicely, It may even require a oil restrictor in the oil feed line,some do some don't we will cross that bridge when we get to it.
