I bought a few of these old boat hydroplane intakes a few years ago, with the intentions of making them into an efi setup. Well I had to change the manifold gasket on my 77 280z turbo this week. So I figured while I had the manifold off, what better excuse to make a ITB turbo intake for it. SO this is what I have come up with so far. It uses 44mm throttle plates, and full tapered runners. I built .75" radius velocity stacks on the inside for better flow entrance. The velocity stacks are also fully polished. I also lightened up the intake as much as possible on the peices that I built. I see alot of custom intakes, and I have one word, HEAVY. SO as you can see I milled out the velocity stack plate for maximum weight removal. I also like making intakes as much of a bolt on as possible. So I utilize the stock throttle linkage. I fitted the TPS inside the cab also, since with Megasquirt, you can program WOT, and Closed throttle, and it takes a linear function from those two points. I have not installed the injectors yet, but they will be ABOVE the throttle plates for better fuel atomization. This is just my daily driver z at the moment, and I wanted a bit more power.
