The 1G Eclipse is a beloved platform among car enthusiasts, known for its potential in performance upgrades. One of the most impactful upgrades you can make is to the fuel system. By installing high-flow fuel pumps and injectors, you can achieve significant power gains and improve the reliability of your engine under boost. In this article, we will explore the benefits of upgrading your fuel system and the steps involved in making these enhancements.
Why Upgrade Your Fuel System?
Upgrading the fuel system in your 1G Eclipse is essential for several reasons:
- Increased Power Output: A high-flow fuel pump and larger injectors can provide the necessary fuel to support higher horsepower levels.
- Improved Engine Reliability: Ensuring adequate fuel delivery helps prevent lean conditions that can lead to engine damage.
- Enhanced Tuning Capability: With more fuel available, you can tune your engine for optimal performance, especially when adding forced induction.
Choosing the Right Components
When upgrading your fuel system, it’s crucial to select the right components to match your performance goals. Here’s what you need to consider:
High-Flow Fuel Pumps
A high-flow fuel pump is vital for ensuring that your engine receives enough fuel, especially when running higher boost levels. Look for pumps that can support at least 255 liters per hour (LPH) to provide adequate fuel flow.
Fuel Injectors
Upgrading your fuel injectors is equally important. Larger injectors allow for increased fuel delivery, which is necessary for higher horsepower applications. Consider injectors rated for 550cc to 750cc, depending on your power goals.
Installation Process
Installing a high-flow fuel pump and injectors may seem daunting, but with the right tools and guidance, it can be a straightforward process. Here’s a step-by-step guide:
Tools Required
- Socket set
- Wrenches
- Fuel line disconnect tool
- Safety glasses
- Shop towels
Step-by-Step Installation
Follow these steps to install your new fuel pump and injectors:
- 1. Relieve Fuel Pressure: Start by disconnecting the fuel pump fuse and running the engine until it stalls. This relieves pressure in the fuel lines.
- 2. Remove the Fuel Pump: Access the fuel pump by removing the rear seat and the fuel pump access cover. Disconnect the wiring and fuel lines, then remove the pump.
- 3. Install the New Pump: Place the new high-flow fuel pump in the housing, ensuring proper alignment. Reconnect the fuel lines and wiring.
- 4. Replace Fuel Injectors: Remove the intake manifold to access the fuel rail. Disconnect the fuel rail and replace the old injectors with the new ones, ensuring proper sealing.
- 5. Reassemble and Test: Reassemble all components, reconnect the battery, and start the engine. Check for leaks and ensure proper fuel delivery.
Tuning Your 1G Eclipse
After upgrading the fuel system, tuning your engine is essential to maximize performance. A proper tune ensures that your engine runs efficiently and safely. Here are some tuning options:
ECU Tuning
Consider investing in an aftermarket ECU or tuning software that allows for custom tuning. This will enable you to adjust fuel maps and ignition timing to match your new fuel system.
Dyno Tuning
For the best results, take your 1G Eclipse to a professional tuner who can perform a dyno tune. This will ensure that your engine is running at its peak performance with the new fuel system upgrades.
Conclusion
Upgrading the fuel system in your 1G Eclipse with high-flow fuel pumps and injectors is a crucial step in achieving reliable power gains. With the right components and a proper installation, you can enhance your vehicle’s performance and ensure it runs smoothly under increased demands. Don’t forget to tune your engine to take full advantage of these upgrades, and enjoy the thrill of driving a more powerful 1G Eclipse!
