The 2G Eclipse is a popular platform for performance enthusiasts looking to enhance their vehicle’s capabilities. Upgrading fuel injectors and boost controllers is a crucial step in optimizing performance. This guide will walk you through the installation process step-by-step.
Tools and Materials Needed
- New fuel injectors
- Boost controller
- Socket set
- Wrenches
- Screwdrivers
- Fuel line disconnect tool
- Electrical tape
- Vacuum line
- Safety glasses
- Shop towels
Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all necessary tools and materials. Disconnect the battery to prevent any electrical issues during the process.
Step 1: Removing the Old Fuel Injectors
Start by removing the intake manifold to access the fuel rail. Follow these steps:
- Remove the air intake duct.
- Disconnect the throttle body and any attached sensors.
- Unbolt the intake manifold from the engine block.
- Carefully lift the manifold off, exposing the fuel rail.
Next, disconnect the fuel rail:
- Use the fuel line disconnect tool to detach the fuel lines.
- Unbolt the fuel rail from the engine.
- Remove the old injectors from the rail.
Step 2: Installing New Fuel Injectors
With the old injectors removed, it’s time to install the new ones:
- Lubricate the O-rings of the new injectors with a small amount of engine oil.
- Insert the new injectors into the fuel rail.
- Reattach the fuel rail to the engine, ensuring it is secure.
- Reconnect the fuel lines to the rail.
Step 3: Installing the Boost Controller
Now that the fuel injectors are in place, you can proceed to install the boost controller:
- Choose an appropriate location for the boost controller inside the cabin.
- Run the vacuum line from the boost controller to the intake manifold.
- Connect the electrical wiring according to the manufacturer’s instructions.
- Secure the boost controller in place.
Step 4: Reassembling the Intake Manifold
With the fuel injectors and boost controller installed, it’s time to reassemble the intake manifold:
- Place the intake manifold back onto the engine.
- Reconnect the throttle body and sensors.
- Reattach the air intake duct.
Step 5: Final Checks and Reconnection
Before starting the engine, double-check all connections:
- Ensure all bolts are tightened.
- Verify that the fuel lines are securely connected.
- Check the wiring for the boost controller.
Once everything is in place, reconnect the battery.
Step 6: Testing the Installation
Start the engine and listen for any unusual sounds. Check for fuel leaks around the injectors and fuel rail. Monitor the boost controller settings to ensure it is functioning correctly.
Tuning and Final Adjustments
After confirming that everything is working properly, consider getting your vehicle tuned to maximize performance. A professional tune can help optimize fuel delivery and boost levels for the best results.
Conclusion
Upgrading fuel injectors and boost controllers on a 2G Eclipse can significantly enhance performance. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved power and efficiency.
