Maybe a list of what all is needed to do this.
My truck will only make 30psi of boost, need to check mine.

   

That’s what I made up. Couple pieces of 4” exhaust pipe, with the ends capped. One end I had a bung welded in for an airline fitting. That should do the CAC.

The other piece for the turbo is just a turbo exhaust flange.

I used air line fittings and a pressure regulator from Napa and made my own pressure tool
