You need a recirculation valve. I know some BOVs have kits to convert them into this, but I can’t imagine it’s that hard to find a simple or stock one. The factory Nissan ones on my Z are good to something silly like 30lbs of b00st.
if you’re looking for aftermarket, Synapse makes a FANTASTIC bov, and they have kits for recirculating…The sponsor Swerve Motorsports on here is a Synapse vendor if you’re looking for a reputable place to buy one
