Default any fuel system upgrades necessary for stage 2 N/A mods?

I am gonna get cams and some other N/A goodies! Do I need to do anything to my fuel system? www.northursalia.com have a really interesting fuel rail mod. Is this necessary? Will I need a new fuel pump or FPR? Thanks!

A bigger fuel pump and adjustable fuel pressure regulator will help, but there is no need for bigger injectors until you max out (static) the stockers. If you have a high end 02 sensor and a S-AFC you can determine the ideal set up for the best a/f ratio.

Good luck with the build.

N/A all the way!!!
