If I get time this weekend I will remove the turbo drip tank and run straight from the bottom of the turbo to the sump cover.

Plus points :
No cavitation from a scavenger pump.
No pump to go wrong.
No noise from pump.

Minus points :
No drip tank for turbo.

I have ordered a AN-10 one way check valve that I will put closest to the sump plate. This should stop oil going back towards the turbo from the sump.

The old BAE turbo kit and many other people run a gravity drain to the left valve cover and this works. So seeing as the sump cover is even lover with a greater fall that should only help.
Plus the sump pump will be sucking the oil from the bottom of the sump and therefore also the turbo drain, so giving some additional help to the gravity drain. This is something that doesn't happen when feeding to the valve cover.

I have the TurboKraft KKK oil feed kit, this has a reducer so the KKK is not over oiled and also the oil cut off, so when the engine is turned off the oil supply to the turbo is stopped. This will hopefully reduce the need for a drip tank.

I will try it with all AN-10 fitting and hose, hopefully this should be fine.

If I can get some I will try some clear hose so I can monitor the oil drain and get a video of it.

So I take it the factory cam scavenger pump does not cause cavitation??
