Any suggestions on which one to run? It'll probably be between 9-12 psi when all is said and done.

Also, what do I need to make it recirculating? (don't wanna run rich between shifts and be a chump just for the bigger sound, now do we?) Just an attachment, or another hose?

two rotors

My plan is to use one off a Turbo II--it operates only when the the throttle closes and a vacuum of about 11in Hg is applied to the valve operator.If you look on the RX7 forum you can access the TII manual and see the set up.Presure control in the air intake system is by waste gate action.
