Has anyone used or seen these before:

20B Triple Throttle Body

I understand how it would work on a N/A engine (just throw an aircleaner on top and away you go) but what is needed to get this installed on a turbo engine? How do you seal the tops of the venturies so that you don't lose boost?

 

One other thing that I noticed was that there were only 3 injectors. Does this mean that you would have to purchase one for the primaries and one for the secondaries?

I believe the stock system is more than capable for what I am doing. I'm just curious about how this system would be installed and what performance benefits one would expect (if any).

 

That manifold they show is for peripheral ports. Since the manifold is not included, do they have one for side ports?
