My advice would be to call Shad at Driving Ambition.

It's my understanding that Comptech did play around with some 2.3L compressors, but didn't produce kits with them. To me it looks like someone with the know-how put this together with the Comptech boost-a-pump fueling arrangement. If that is the case it very well could have been Shad. The pulley looks huge so it may very well be okay to run it with those injectors, if you're running at 6psi of boost max. That was the targeted max boost level on the standard Comptech kits, with the 1.6L compressors. However, without talking to Shad I highly advise against it as others have. As a point of reference, I upgraded to a 2.3L compressor and had a 4.6" pulley made by Comptech that produced roughly 8psi of boost on my intercooled 2.3L, which would be roughly 9psi on a non-intercooled car with a 3.0 engine.
As far as an ACM goes, I thought the Comptech NSX supercharger kit had the boost-a-pump and an ESM. It sounds like you have the boost-a-pump box that sits on the inside firewall by the fuel pump relay. The ESM is a little black box that was spiced into the wiring harness that made sure that map sensor never saw over 5 volts.

Lastly, it looks like the screw plugs are not in the lower right side of the manifold. These are used for boost gauges or what ever else has a 1/4" npt fitting. Anyhow, you will want to block them off if you haven't already.
