Bumping this thread yet again, has anyone ever tried putting yet another vacuum regulating valve on the hose that goes between the turbo inlet? Something local owners have mentioned is the Radium breather pipes de-restrict the valve cover but it actually produces an undesirable outcome in practice, way too much air is sucked out of the crankcase and a ton of oil comes with it as well. As far as I can tell the PCV diaphragm in these modern euro wet sump performance engines is active during boost as well, there's just a check valve to block boost from entering the valve cover and crankcase as there's no inherent check valve function in these diaphragm-type valves. Hopefully I'll be able to try some of this out soon. The Volvo XC90 4.4 V8 has a nice external version of these things. -

So when will the Samsonas, twin scroll turbo setup on go? -
I have started repairing them but left it for more important things... Rather than clutter your post, this is the link to my build - https://www.sau.com.au/forums/forum/190-members-cars-project-overhauls-restorations/. One day I'll go back and replace the photos Photobucket deleted...
