I would say stock pressure pump and recalibrate computer for different sized injectors. I'm not familar with which injectors are the grey or green ones. are they stock ones from different years. In any case if they are a different size you'll need to have the PCM tuned for them. The way I see it greatly altering the pressure to make them flow like the older smaller(I'm assuming) injectors would negate the benefits of large injectors.
All you need is a pump able to push 58psi, and enough volume to keep it there for the given amount of fuel you plan on consuming. The gas tank has it's own pressure regulator, it uses a pseudo "return line" to allow excess fuel to bleed to the tank as the pressure builds.
