I'm working on a dual fuel rail set up right now for my own build. It's going hand in hand with a new manifold. I'm also doing triple 255's in tank.
running my primary injectors on a reasonable street sized injector and factory fpr and a single 255...then two of the 255's feed a turbosmart fpr and runs my big injectors...they all collect to one return line to the tank.
Should have no issues with street driving as it is mearly factory fuel system for driving around town...pending where you have your secondary injectors to come on.
not to hi-jack the thread, but I'm curious, what EMS are you using? I was considering the hydra but when talking to Phil, he was not all too anxious about using an aux injector setup, which is one of the reasons i'm waiting on the AEM EMS to be released for the DBW cars.

That being said, for the original poster, I've been told that people have gotten 1600cc injectors to idle, but when running a built motor with a nice cam, it would probably be much more drivable if you could run a fuel system much closer to stock (ie 800cc injectors or smaller) and then have an aux set of 1000cc injectors, or maybe even larger, kick in at some point.
