I haven't gone FI just yet, but have been looking at several of the options for fuel delivery, pumps, etc, to keep the car relatively reliable before I make the big jump.

I came across some SARD 650cc and 800cc top feed injectors that supposedly work with the stock rail.

SARD = Nippon Denso = Factory Nissan quality = good in my books...

...but does anyone have any experience using these SARD/Denso injectors on their Z? These are high imp. injectors, and they have some fuel rail options as well. I'm probably wrong, but I was under the impression that the factory fuel rail isn't sufficient for that much injection?? (650cc, 800cc)
