John, I have a Rayjay on my VW.
I do not know how the Revmaster pump is plumbed, but I am running a converted CB Performance pump. Video can be found here - https://youtu.be/y9lZKKz5rPc <https://youtu.be/y9lZKKz5rPc> Concerning the oil spitting, are you running a restrictor in the oil feed line to the turbo? If not you will likely need one. I believe the opening in mine is .04. Even then, until the turbos seals are warm I get a little oil spitting out of the exhaust. Mine could stand to be a little smaller I suspect. I get no popping sounds on cool down. Clarks Corviar has parts for these turbos. Here are two reference links that I have found useful.
