Hey! I know there is a lot out there, but want to get some tips from you guys!

I have a 335 with N54 and going to run Speedtech single kit. This already has a fitting in the inlet pipe to the turbo, so might as well use this to draw "vacuum" from a catch can.
I wonder what you suggest doing with rest of the pcv system?

I kinda want to plug the pcv ports so I`ll never have problems with it. Should I might as well run a flapper delete (like the one below) and run a hose straight to a catchcan which draws vacuum from the turbo? And just install a pcv delete plug if it exisist?

Dual catch cans with external pcv setup, high side goes back into turbo filter. Or straight up VTA. I run VTA and daily my car, if your engine doesn’t have a fuck ton of blowby and you setup your can properly you won’t get any smells or smoke

Thanks for input guys. When you run VTA do you run 2 hoses out of the valve cover, or do you plug the pcv valve and only vent from the flapper delete?

I have the head ports plugged, vent from both ports on the valve cover and have the VTT oil cap breather

Theres been a lot of posts on PCV setups lately, I made a detailed post that's linked in most of them for a pretty fool-proof PCV system that has full vacuum on decel/idle and full VTA on boost to help with both carbon buildup and engine longevity.
