The first generation Honda NSX is a beloved sports car that has captured the hearts of enthusiasts around the world. However, for those looking to increase performance, upgrading components such as the fuel pump and injectors can yield significant power gains. In this article, we will explore the benefits of installing a SARD fuel pump and larger injectors, along with an overview of the associated costs.
Understanding the NSX Fuel System
The NSX is equipped with a sophisticated fuel system designed to deliver optimal performance. However, when increasing horsepower through modifications such as turbocharging or supercharging, the stock fuel pump and injectors may struggle to meet the higher fuel demands.
Stock Fuel Pump Limitations
The factory fuel pump is adequate for stock power levels but can become a bottleneck when pushing the engine beyond its limits. Upgrading to a high-performance fuel pump, such as the SARD fuel pump, can ensure that your engine receives a consistent and adequate supply of fuel.
Benefits of Upgrading to a SARD Fuel Pump
The SARD fuel pump is designed for high-performance applications and offers several advantages over the stock pump:
- Increased Fuel Flow: The SARD pump can deliver a higher volume of fuel, which is essential for modified engines.
- Improved Reliability: Designed for performance, SARD pumps are built to withstand higher pressures and temperatures.
- Better Fuel Atomization: Enhanced flow rates lead to improved fuel atomization, resulting in better combustion.
Larger Injectors: Enhancing Fuel Delivery
In conjunction with a new fuel pump, larger fuel injectors are crucial for providing the necessary fuel to match the increased air intake from modifications. Upgrading your injectors ensures that your engine receives the correct fuel-to-air ratio, which is vital for performance and engine health.
Choosing the Right Injectors
When selecting larger injectors, consider the following:
- Flow Rate: Choose injectors with a flow rate that matches your power goals.
- Compatibility: Ensure the injectors are compatible with the NSX’s fuel rail and connectors.
- Brand Reputation: Opt for reputable brands known for quality and performance.
Power Gains from Upgrades
Upgrading to a SARD fuel pump and larger injectors can lead to significant power gains. While actual numbers will vary depending on other modifications and tuning, many NSX owners report increases in horsepower and torque after these upgrades.
Expected Power Gains
On average, enthusiasts have experienced:
- Horsepower Increase: 30-50 HP depending on tuning and other modifications.
- Torque Increase: 20-40 lb-ft, enhancing overall drivability and responsiveness.
Cost Considerations
While performance upgrades can be exciting, it’s essential to consider the costs involved. Below is a breakdown of the expected costs for a SARD fuel pump and larger injectors:
- SARD Fuel Pump: Approximately $300-$500 depending on the retailer.
- Larger Injectors: Typically range from $400-$800 depending on the brand and size.
- Tuning Costs: Expect to pay $200-$500 for a proper tune to maximize performance.
Installation Process
Installing a SARD fuel pump and larger injectors requires some mechanical skill. Here’s a brief overview of the process:
- Fuel Pump Installation: Remove the fuel tank to access the stock pump, replace it with the SARD pump, and reconnect all lines.
- Injector Installation: Remove the intake manifold to access the injectors, replace them with the new larger injectors, and ensure proper sealing.
- Tuning: After installation, have the vehicle tuned to optimize performance and ensure the engine runs smoothly.
Conclusion
Boosting your first-gen NSX with a SARD fuel pump and larger injectors can significantly enhance performance and driving experience. While the upfront costs may seem high, the power gains and improved reliability make these upgrades worthwhile for any serious NSX enthusiast.
