I was trying to find some injectors, fuel rail and pump option for the RS6 and not having any luck.

Im looking for something that will flow in the 700awhp(or atleast 600awhp)

Im thinking 80lbs injectors, and aem 320lph pump.

What is the limit of stock fuel rail? and how come I cant seem to find any aftermarket injectors?

One option ive found (from annother member) is the use of 1.8t rail with b5 s4 injectors. Anyone tried this combo?
