The next step was to get my model going. I came across this drawing for the flange on some Swedish website for boosted cars...
The rest of the measurements I just measured off of my manifold...
Adding some 1.75" x 0.125" wall tubing cut at a 24 degree angle. (The cross section of the 24 degree cut happens to match up fairly nicely with the cross section of the manifold)
I roughly measured up the throttle bodies. In this picture they are spaced on 91mm centres just like the intake ports...
Putting it all together with some 2" to 1.75" silicone reducers looks something like this...
And with a rough estimate of the brake booster (I'm not actually sure of the placement of the booster depth wise but that's not really the limiting factor in this case)...
