Can't see why 5 lb or so of boost would cause problems with the block-crankcase joint; we ran 8.5 lb of boost on an A7 racecar for several seasons without any issues with that joint. I'm not sure I would run such a fine filter as 70 microns on the suck side of the oil pump though; something a bit more like a tea strainer on the inlet side would be all that's necessary to protect the pump along with a conventional full flow filter on the outlet side.
