Cost Analysis: Installing an E85 Fuel System on a Nissan Gt-r—what’s the Investment and Power Returned?

by

The Nissan GT-R is renowned for its performance and engineering excellence. One modification that enthusiasts often consider is the installation of an E85 fuel system. This article will analyze the costs associated with this upgrade and evaluate the potential power returns.

Understanding E85 Fuel

E85 fuel is a blend of 85% ethanol and 15% gasoline. It offers several advantages for high-performance vehicles, including a higher octane rating and the potential for increased power output. However, it also requires specific modifications to the fuel system.

Cost Breakdown of Installing an E85 Fuel System

Installing an E85 fuel system on a Nissan GT-R involves several components and labor costs. Below is a detailed breakdown of these expenses.

  • Fuel Injectors: Upgrading to high-flow fuel injectors is essential. Cost: $600 – $1,200.
  • Fuel Pump: A compatible fuel pump is necessary to handle the ethanol blend. Cost: $200 – $500.
  • Fuel Lines: Ethanol can degrade standard fuel lines. Upgraded lines are recommended. Cost: $150 – $300.
  • Tuning: Proper tuning is crucial for optimal performance. Cost: $500 – $1,000.
  • Labor Costs: Professional installation may be required. Cost: $300 – $600.

In total, the investment for installing an E85 fuel system on a Nissan GT-R can range from approximately $1,750 to $3,600, depending on the components chosen and labor costs.

Power Returns from E85 Fuel System Installation

One of the primary reasons for upgrading to an E85 fuel system is the potential increase in horsepower. The following factors contribute to the power gains:

  • Higher Octane Rating: E85 has a higher octane rating than regular gasoline, allowing for more aggressive tuning.
  • Increased Fuel Volume: Ethanol has a lower energy content, requiring more fuel to achieve the same power, which can lead to increased horsepower.
  • Cooling Effect: Ethanol has a cooling effect during combustion, which can lead to more efficient performance.

Enthusiasts can expect power gains of approximately 10-20% after installing an E85 fuel system, depending on the extent of tuning and other modifications.

Considerations Before Upgrading

While the benefits of an E85 fuel system are enticing, there are several considerations to keep in mind:

  • Availability: E85 fuel may not be readily available in all areas.
  • Fuel Economy: Ethanol generally has a lower energy density, which may result in reduced fuel economy.
  • Corrosion: Ethanol can be corrosive to certain materials, necessitating the use of compatible components.
  • Emissions: E85 can produce different emissions compared to gasoline, which may be a concern for some owners.

Weighing these factors is crucial before deciding to install an E85 fuel system on a Nissan GT-R.

Conclusion

Installing an E85 fuel system on a Nissan GT-R can be a worthwhile investment for enthusiasts seeking increased performance. With a total investment ranging from $1,750 to $3,600 and potential power gains of 10-20%, it offers a compelling option for those looking to enhance their vehicle’s capabilities. However, careful consideration of the associated factors is essential to ensure a successful upgrade.
