Project DBA R35 Nissan GT-R Bolt On Power Mods Part 2, Fueling for 1000 Hp

The sender unit was then bolted to the bracket on the side of the Radium Engineering hanger.

The sensor wires were then cut, stripped, and terminated.

The fuel level sender wires can now be attached to the studs on the Radium Engineering fuel tank top. The fuel pump wires were also attached to the correct studs. Care was taken to maintain separation and maximum distance on all the wire ends to avoid shorts.  Finally, the tank top was attached to the pump pressure manifold.  The Radium Engineering fuel pump hanger and surge tank are now ready to be installed on the fuel tank.

Now the pump’s power and fuel level sender wires are attached to the terminal pass though studs on the tank top.  In order to assure that our fuel pumps get the most possible voltage at all times, we used relays so the stock wiring just does the switching for the pumps that are wired directly to the battery with heavy gauge wire.

One note when tightening down the terminals, don’t overdo it or the stud may spin and the ring terminal on the inside of the tank may contact each other and short out and the pumps will not turn on.

Now the tank top access panel is reinstalled and our fuel pumps and surge tank are ready.

For injectors, we replaced the stock Nissan 570cc injectors with Cobb’s 1300cc X2 injectors.  The Cobb injectors by Injector Dynamics are more than double the factory size and should provide enough fuel for our anticipated power levels.  The injectors come with plug adaptors to make the installation easy and reversible.
