I killed the PCV, I run a -10 line from the turbo-side of the valve cover to the small Jeg's can with steel wool stuffed in the top. I have an insanely low amount of blow-by and I accumulate about 2oz of water/fuel in the can after 2-hours of track time...and I'm over-estimating.

Depends entirely on the power level, but at some point you will either need a quality ($$) air-oil separator with a gravity drain and a quality vacuum source, or a separator+vacuum pump setup ($$$), or a dry sump ($$$$$).

power level is around the 300whp level. FM bottom end, fettled head, GT2871. nothing crazy. seems to have very little blow by.
what about running pcv with a separator between the pcv and the inlet manifold and a separate catch can on the exhaust side for when under boost?

As you can see, Emilio is considering a setup with a vacuum pump at this time. As higher priority concerns have been taken care of, I think people have more time to dot the "I"s and dash the "T"s sort-of-speak.
Anyways, for now I would listen to what Hustler said on this one (or try your hands at a vacuum setup).
OHhh, before I forget. There is some non-miata relevant information on this:
