What’s the Best Way to Upgrade the Fuel System in a Nissan GTR for High Horsepower Applications?

As proud owners of Nissan GTRs, you understand the potential power that lies within the heart of your beast, the engine. In your quest to maximize this power, you may consider upgrading several components. One such crucial area is the fuel system. Upgrading the fuel system can significantly boost your Nissan’s performance. Whether it’s for daily driving, drag racing, or circuit racing, an optimized fuel system ensures your engine gets the right fuel amount whenever it needs it. So, how can you upgrade the fuel system in your Nissan GTR for high horsepower applications? This article will walk you through the process.

Upgrading the Fuel Pump

The fuel pump is an essential part of your fuel system. It’s the component responsible for transferring fuel from the tank to the engine. An underperforming pump can lead to a decrease in engine performance. Therefore, an upgrade to a high-performance pump is a reasonable step.

When upgrading, you have the option of going for a single or dual pump system. A single pump system is suitable for moderate horsepower applications, but for high horsepower applications, a dual pump system is recommended. Companies like Radium Engineering offer a dual pump system specifically designed for the Nissan GTR.

To further enhance the performance of your fuel pump, consider adding a fuel pump speed controller. This device will allow you to control the speed of your pump, ensuring it delivers just the right amount of fuel at the optimal time.

Choosing the Right Fuel Injectors

Fuel injectors play a crucial role in delivering fuel to your engine’s combustion chamber. For high horsepower applications, you need to upgrade your injectors to match the increased fuel demand.

There are two types of injectors you could consider: OEM (Original Equipment Manufacturer) or custom. OEM injectors are usually the safest bet, as they’re specifically designed for your vehicle. However, for high horsepower applications, custom injectors might be a better choice. Companies like Ferrea offer high-performance injectors that can handle the increased fuel demand.

It’s important to remember that bigger isn’t always better when it comes to injectors. You need injectors that can deliver the right amount of fuel, not necessarily the most fuel.

Updating the Fuel Rails and Lines

Your fuel system’s efficiency is as strong as its weakest link, which means you should also consider the fuel rails and lines. These components are responsible for delivering fuel from the pump to the injectors.

For a high-performance Nissan GTR, you will want to upgrade to performance-grade fuel rails and lines. These should be able to withstand the increased fuel pressure from your upgraded pump and injectors. A company known for producing reliable fuel rails and lines is Aeromotive.

Optimizing the Fuel Pressure Regulator

The fuel pressure regulator ensures that your fuel injectors receive fuel at the correct pressure. If the pressure is too high, it could lead to leaks or damage. If it’s too low, your engine might not get enough fuel.

For high horsepower applications, consider upgrading your fuel pressure regulator to a performance model. This will help maintain optimal fuel pressure despite the increased demand.

Incorporating a Custom Intake and Exhaust System

While not directly part of the fuel system, the intake and exhaust system play a significant role in engine performance. Upgrading to a custom intake system can increase airflow to your engine, boosting power. Similarly, an upgraded exhaust system can improve exhaust gas flow, increasing engine efficiency.

Companies like AEM and Borla offer high-performance intake and exhaust systems designed specifically for the Nissan GTR. While these upgrades might not directly affect fuel flow, they can enhance overall engine performance, offering a noticeable power boost.

In summary, upgrading the fuel system in your Nissan GTR for high horsepower applications involves several steps. From upgrading the fuel pump and injectors to optimizing the fuel pressure regulator and incorporating a custom intake and exhaust system, each step brings you closer to a more powerful and efficient engine. As always, remember to consider your unique needs and budget when making these upgrades.

Utilizing a Comprehensive Stage Package

A stage package is a comprehensive kit designed to upgrade multiple aspects of your vehicle simultaneously. It’s a popular option for many car enthusiasts seeking to enhance their vehicle’s horsepower significantly. These kits often include parts like high flow fuel pumps, improved spark plugs, and more efficient intercooler piping.

Boost Logic, a well-respected name in the automotive industry, offers a stage package that includes a variety of upgrades for your Nissan GTR. This package consists of everything from a high flow fuel pump to titanium retainers and valves from Ferrea.

The fuel pump included in the Boost Logic package is a brushless model designed to deliver more fuel to the engine, resulting in higher horsepower. The fuel pump operates smoothly and efficiently, contributing to better overall performance.

The high flow fuel rails in this stage package are made from durable stainless steel. These fuel rails are designed to withstand high pressure and flow rates, ensuring your engine gets the fuel it needs when it requires it.

In addition to the fuel system upgrades, the stage package also includes improvements to the exhaust system. An efficient exhaust system keeps unnecessary backpressure from building up and hindering engine performance.

Cruise control and launch control are two other features included in the Boost Logic stage package. These features provide improved control over your vehicle, particularly when launching from a standstill or maintaining a steady speed on highways.

Incorporating Advanced Engine Management

Engine management involves controlling and optimizing various engine parameters for improved performance. It requires the use of an engine management system (EMS), a device that manages multiple engine components, including the fuel system.

AMS Performance is a renowned company that produces advanced engine management systems. Their products help to monitor and adjust fuel pressure, control the fuel injectors and fuel pump, and manage other engine parameters.

Having a proper EMS in your Nissan GTR enables you to get the most out of your upgraded fuel system. For instance, it can adjust the fuel pressure according to the engine’s requirements, ensuring that the fuel pump and injectors work effectively.

Advanced engine management can also help you optimize the performance of your spark plugs. By controlling the spark timing, an EMS can ensure that the fuel-air mixture in your engine’s cylinders ignites at the optimal time, maximizing engine performance.

Conclusion: Perfecting Your Nissan GTR’s Performance

Unlocking your Nissan GTR’s full potential requires careful attention to the fuel system. High-performance fuel pumps, custom fuel rails, optimized fuel pressure regulators, and high flow injectors all play a crucial role in enhancing your vehicle’s horsepower.

Incorporating a comprehensive stage package, such as the one from Boost Logic, can simplify the process by providing a curated set of high-performance components specifically designed for your Nissan GTR. Meanwhile, implementing an advanced engine management system can help you monitor and control these upgrades, ensuring optimal performance.

Ultimately, these upgrades, alongside proper engine management, can transform your Nissan GTR into a high horsepower beast. Whether you use your GTR for daily driving or competitive racing, these enhancements will undoubtedly magnify its performance, guaranteeing a thrilling driving experience every time.
