Starting a new build looking into FI

Postby zachggus » Fri May 10, 2019 5:20 pm

I have an 03 g35 sedan looking to make some power and eventually go FI. I built the short block to handle boost. Forged pistons and rods studded the crank and the heads. Where to start with mods. I want to get the fuel system up to par. If I upgrade injectors to 600cc with added return system and high flow pump will I be running super rich without a tune or can the stock ecu make the adjustments. I will soon be installing high flow cats and a plenum spacer and don’t want to run lean. Also I will be installing regulator to fuel system. I know stock psi is 51 but more hp I need more pressure any suggestions.
