Sorry for the delayed response. Using picture in first post remove the metal rod completely. and the rubber diaphragm. Basically remove everything so that you have a plastic cover to plug the DISA hole in the manifold. Plug any holes in your new plastic DISA cover plate with JB Weld quick (My favorite)
When the DISA is gutted correctly you will have a plastic plate with o-ring which you bolt into the manifold DISA hole with the original 3 bolts.
This is only needed for a boosted car. I ran a DISA on a turbo M44 and the DISA got destroyed by the boost hitting it so hard. The parts went down the intake and bent 2 valves.
