I am installing my turbo on my mk4 AEG and I removed the secondary air injection system. Since I am using the standard cast iron manifold the secodary injection holes are open in the head. I am not sure what to use to plug them safely.
I've already machined and aluminum inlet flange and a steel discahrge flange for my turbo. I want to make a 1/8" "gasket" of sorts to go in between the manifold and the head. I've got it tooled up, just trying to decide what material to make it in. Aluminum would be easiest for my CNC and it would be quick. I've got shelves of aluminum on hand
I've heard, and thrown some #'s around and it doesn't seem like Aluminum is the best thing to use in the application. I'd do steel but it will take forever to machine. I am thinking it will be just fine since the head is aluminum I figure why not? Exhaust gasses will be flying by it and most of the heat will be absorbed by the turbocharger.
Any thoughts?
