Thank you for your reply.
I'm thinking that 3 injectors should be enough if we space them out a bit (size wise). I say this because the intercoolers dump into the throttle body very close to each other. Please see attached picture of where I'd like to install the injectors.
This close together, I wouldn't think they would have to be evenly matched (size wise), since they will be so close together? For example, I could get a 450,cc, a 350cc, and say, a 180cc injector and mix and match them until the better of the combinations reveals itself. I'm not certain what injector sizes are available from you guys, but I hope you understand what I'm saying? Because I sure don't...
