I Don't know.
I'm currently looking at making a mandrel and pump mount much like the Cosworth one that would work with the Aviad Pump. Cosworth has officially stopped making their Subaru Dry Sump system.
So Cosworth either determined that the dry sumps don't work or not enough volume to keep producing them, they are still making the baffle and pan though. It could be that Subaru engines are just not acceptable/designed for road racing no matter what
