Here are some pics.
Above are the bodies after being milled flat and
mounted on the airbox.
At right are the injectors from a 2.0 Mazda, and the plugs made to fit inside the piston bore. The recess for the injectors is angled at approx. 45 degrees, which points down stream toward the head. I recycled the dashpot portion with bolt tabs as retainers for the plugs.
I made a TPI mount by drilling and tapping the throttle shaft of #2 carb. A little JB weld and a bit of thin wall and I have a place for the TPI to live.
You can see the TPI in this picture.
At first I thought I could use the fuel rail that came with the injectors, why not! The spacing was perfect and I had them in hand. If I would have brazed them, it would have been OK. As it was, they were not going to fly, so I bought some brass fittings and a piece of fuel rail and made a stronger system. These pictures show the first fuel rail setup.
I needed to have an Idle air circuit as well as vacuum /pressure port for the eventual turbo setup. you can see the intake air temp sensor in the middle of the air box.
