Which BOV - Turbo Carb DIY Build

I'm building a DIY turbo kit. I plan to run a recirculating BOV, diverter, comp bypass whatever you want to call it. I have a 1" beaded tube on both my compressor inlet and outlet. Just need a valve in between. I was thinking one of the cheap Audi diverter valves but they are not adjustable? Its only a 440 and I want it open at idle. Any recommendations?

How about this one and I adjust the springs? Or perhaps I go with something else?

bump, looking for any recommendations on a recirculating valve that has been successfully dialed or modified for our low vacuum engines and that is adjustable for fine tuning day to day, idle changes, etc.

Bump, someone has to have built a carb turbo with recirc. Am I in the wrong forum?
