Dipping a toe in the rabbit hole...

As far as a return fuel system not needed, unless you want to go for max power with E85.
I have no need for that on my daily, but I do have the return fuel system since I bought it all used as a package deal. Thanks again Aaron. :-)

If I remember correctly, the GTR of its first MY has already included a RFS, and it's only 480-hp output in engine on pumping gas... (today, any boosted Z can easily go over this number) I usually tell my friends that RFS has merits you barely see, often overlooked. It allows your boosted Z runs more reliably and "consistently" under WOT no matter what fuel your using. For FF, it's definitely a MUST in order to keep the pressure on the fuel rails truly regulated, thereby making each of the injectors outputs equally regardless of their position difference and increased fuel volume. From my experiences, the injector duty drops by almost 20 percentage after the RFS was added (gas). This significaly alleviates the loading of the fuel system. As a result, I see no reason that anyone choosing to go forced induction should not include a RFS for our car IMO. You may save some money for now but you may spend more in the future. Especially you can save lots of labor fee if you have it installed along with your charger kit. Installing all of them at the same time is much cheaper than installing them separately.

Considering the a2a kit can make over 500whp without even trying, a RFS is a no brainer.
