The manifold is a great idea. I'm thinking more on each nozzle gets it's own S-HSV. I was going to make a manifold with a common feed and independent outlet's. Or four 1-valve manifolds.

The rest is just a differant way of looking at direct port injection. You know me. The hydraulics have to perfect first. Then we can wonder about how to control it.

At this point it looks better on paper.

Let me know on the stuff for the GSX whenever you get the time.
I can go one of two ways with that car. MAF or Boost.
And as always. Thank You kind sir.
