Installing nitrous can be an exciting way to boost your Subaru WRX’s performance. With the right setup, you can achieve over 100 horsepower increase for under $1,200. This guide will walk you through the process step-by-step, ensuring you get the most out of your nitrous system.
Understanding Nitrous Oxide Systems
Nitrous oxide (N2O) is a powerful oxidizer that can significantly enhance engine performance. When injected into the combustion chamber, it allows for more fuel to be burned, resulting in increased horsepower. Understanding how nitrous systems work is crucial for effective installation and use.
- Types of nitrous systems: wet vs. dry
- Components of a nitrous system
- Safety considerations
Choosing the Right Nitrous Kit
When selecting a nitrous kit for your Subaru WRX, consider the following:
- Type of kit: wet kits are generally easier to install and offer better performance for turbocharged engines.
- Size of the nitrous jets: larger jets provide more power but require careful tuning.
- Brand reputation: choose a kit from a reputable manufacturer for reliability.
Tools and Materials Required
Before you begin the installation, gather the necessary tools and materials:
- Nitrous oxide kit
- Wrenches and sockets
- Drill and drill bits
- Fuel line and fittings
- Electrical connectors
- Safety equipment (gloves, goggles)
Installation Steps
Follow these steps to install your nitrous system:
- Step 1: Disconnect the battery to ensure safety during installation.
- Step 2: Mount the nitrous bottle securely in the trunk or cargo area.
- Step 3: Run the nitrous lines from the bottle to the engine bay, ensuring they are protected from heat and abrasion.
- Step 4: Install the nitrous solenoid in a suitable location, following the manufacturer’s instructions.
- Step 5: Connect the nitrous lines to the solenoid and the intake manifold.
- Step 6: Install the fuel line and ensure it is connected to the nitrous system.
- Step 7: Wire the nitrous system to the vehicle’s electrical system, ensuring proper connections and fuses.
- Step 8: Reconnect the battery and check for leaks in the system.
Tuning Your WRX for Nitrous
After installation, tuning your Subaru WRX is essential to maximize performance and ensure engine safety:
- Adjust the air-fuel ratio for optimal combustion.
- Consider upgrading the ignition system for better spark.
- Use a wideband O2 sensor to monitor air-fuel ratios during tuning.
Roll Racing Tips with Nitrous
When roll racing with nitrous, keep these tips in mind:
- Engage the nitrous system at the right RPM for maximum effectiveness.
- Practice smooth throttle control to prevent wheel spin.
- Be aware of your vehicle’s limits and adjust your nitrous usage accordingly.
Safety Precautions
Safety is paramount when using nitrous. Follow these precautions:
- Always wear safety gear when operating the vehicle.
- Never exceed the recommended nitrous levels for your engine.
- Regularly inspect your nitrous system for leaks or damage.
Conclusion
Installing a nitrous system on your Subaru WRX can deliver impressive performance gains for an affordable price. By following this guide, you can achieve a significant horsepower increase while ensuring safety and reliability. Happy racing!
