Is there a max flow rate for the stock fuel rail? what cc per injector do i need to replace the stock rail? I have ~370cc injectors, no fuel pump yet.

The fuel rail can flow all the fuel you throw at it. The real limiting factor is the fact that it's "barbed" and 99% of all modern fuel injectors are 11mm or 14mm o-ring style. You can try removing the rubber o-ring from the fuel injectors and clamp them on like barbed, but they will inevitably leak as they are not designed to be used in such a way (leaking fuel on hot engine = fire). This is the reason people go with a Pallnet or ProTunerz o-ring fuel rail.
