There are a number of items to consider. The stock Mazda pump is a convenient package. So, good to go there. The Kidney shaped ports and the bearing hole for the pump shaft will be in your new housings. Drillings to connect to the oil pick up pipe and to the outside are required. The stock pump will be more than adequate pressure and volume wise. You can score big on the pickup shape (trumpet bell) and bolt on end with an "O" ring feature. I like the pressure relief at the end of the system (Stock Mazda). With one less rotor spraying oil there will be extra unused oil returning to the pan. You might think about that oil returning to the top of a full engine baffle plate to help reduce foaming.  Stock galleries are fine and a bit bigger than the holes in the stationary gears. Helps to radius those to take off the sharp edges. 

The deeper the pan and the closer to the bottom is the end of the pickup, the less likely it is that the engine can be starved for oil. So, steep climbs and descents and long slips will be worry free.

You can clock the stationary gears to accept incoming oil from any location.

Richard Sohn has done all of this and makes the adapter that puts in 2 cycle oil instead of sump oil. He also has the balance figured out. Another problem solved.

The dry sump system is far more complex and has far more weight and uses a very expensive pump.
Not in the running if I were doing it. If you need massive amounts of oil flow you can buy the pieces of a dry sump pump and just build an external pressure pump and use that on a wet sump engine.

Lynn,   Due to enough ignorance to be embarrassing, I have kept quiet on this one, but since somewhere down the track I am interested in making single rotors with alloy end plates, the oil system comes into full focus among many other things.  Do I go with the stock oil pump or look at a dry sump system for oil?  What oil gallery's should be altered?  Really the gate is wide open with a new casting.  Advice???  Neil.
