Fuel. In order to make horsepower in a Nissan Skyline GT-R, you need fuel and air. The air and fuel mixture are forced into the combustion chamber by our friend, the twin turbochargers(why have one, when you can have two?), which then produces the horsepower/torque we demand with our right foot.

As the horsepower requirements increase, the fuel requirements increase. The fuel system, and that is an important set of words, needs to be adequate enough to supply enough fuel. If you don't supply enough fuel, you will inevitably end up with a dead engine. Another very important thing to note is fuel flow vs fuel pressure vs voltage.
Fuel System:
Fuel Tank
Fuel Pump
Fuel Pulsator
Fuel Pump Control Module (FPCM)
Fuel Relay
Fuel Injectors
Fuel Rail
Fuel Pressure Regulator (FPR)
Fuel Filter
Fuel Lines
ECU
Fuel Pressure
System Voltage
Fuel Surge Tanks
If any part of the fuel system is not adequate, you are just asking for problems. So pay careful attention to it. About 90% of the time we are on a dyno with a car, the fuel system is the limiting factor. Build the fuel system with enough capacity for your horsepower goals.

The questions to ask
- How much horsepower are you looking to make?
- What kind of fuel do you use?
- How much money are you willing to spend?
- How is the car used?
