Ah, interesting. I wonder what the difference between the S4/5 TII pump and the S6+ pump is.

The S6+ pump has an additional cavity on the inlet or outlet side (can't remember and don't have one in front of me). The 3rd gen pump won't work on the S4/5 irons unless you port the iron to match the pump. Think it's been done but a quick search hasn't turned anything up.

There is/was a "comp" pump offered by Mazda Comp for the 12A. It has heat treated shaft and rotors. Other than that there are only stock pumps.
