Adding a nitrous oxide (N2O) kit to your 2018 Ford Focus RS can significantly boost its performance by increasing horsepower. This guide will walk you through the process of installing a nitrous kit, ensuring your Focus RS remains a high-performing machine.
What You Need to Install a Nitrous Kit
- Nitrous Kit: Ensure it's compatible with the 2018 Ford Focus RS.
- Basic Tools: Wrenches, screwdrivers, pliers, and a socket set.
- Safety Gear: Gloves and safety glasses.
- Drill and Bits: For mounting brackets and solenoids.
- Electrical Tools: Wire strippers, connectors, and a multimeter.
- Fuel Pressure Regulator: Ensures proper fuel flow.
- Nitrous and Fuel Solenoids: Controls the flow of nitrous and fuel.
- Nitrous Bottle: The storage tank for nitrous oxide.
- Nitrous and Fuel Lines: High-pressure lines to transport the nitrous and fuel.
- Jets and Nozzles: To control the amount of nitrous injected.
- Mounting Hardware: Brackets, bolts, and screws.
Step-by-Step Installation Guide
1. Preparation
- Safety First: Ensure you have gloves and safety glasses on.
- Disconnect the Battery: Prevents any electrical issues during installation.
- Plan the Layout: Decide where to mount the nitrous bottle, solenoids, and lines.
2. Mounting the Nitrous Bottle
- Choose a Location: Typically in the trunk for balance and safety.
- Secure the Bottle: Use the provided brackets to mount the bottle firmly. Ensure it's accessible for refills and the valve faces the front of the car.
- Install the Blow-Down Tube: Directs excess pressure safely outside the vehicle in case of an overpressure event.
3. Installing the Solenoids
- Mount the Solenoids: Near the intake manifold or throttle body. Use the provided brackets and hardware.
- Connect the Lines: Attach the nitrous line from the bottle to the nitrous solenoid and the fuel line to the fuel solenoid.
- Install Jets: Place the appropriate size jets into the nozzles based on desired horsepower gains.
4. Wiring the System
- Run the Wires: Connect the solenoids to the activation switch and the power source.
- Install the Switch: Typically mounted inside the cabin, within easy reach of the driver.
- Test the Connections: Use a multimeter to ensure all electrical connections are secure.
5. Connecting the Fuel and Nitrous Lines
- Run the Lines: From the solenoids to the intake manifold.
- Secure the Lines: Use clamps and zip ties to keep them away from hot or moving parts.
- Check for Leaks: Pressurize the system and check for any leaks in the lines or connections.
6. Testing and Tuning
- Initial Test: Start the engine and engage the nitrous system briefly to ensure it functions correctly.
- Tuning: It may require adjustments to the fuel pressure and jet sizes to optimize performance and ensure safe operation.
- Professional Dyno Tuning: For precise tuning and to maximize performance gains, consider professional dyno tuning.
