I dont think you need one for this. Check out the fuel/emission section of this manual: 300zx service manual - engine and emission control overall diagram - turbo model Find your FPR ("pressure regulator" - dead center in diagram), find your prvr ("P.R.V.R. control solenoid valve" on diagram). See the line that goes from plenum to prvr? Make it go from plenum to FPR instead. I did this while high so if I can do it you can do it.
