The Subaru WRX has long been a favorite among car enthusiasts, known for its performance and versatility. As power levels increase, especially when tuning for over 400 horsepower, ensuring reliability becomes paramount. This article will explore the benefits of a flex fuel kit and necessary clutch upgrades for WRX owners aiming for high performance.
Understanding Flex Fuel Kits
A flex fuel kit allows your WRX to run on a mixture of gasoline and ethanol. This capability not only increases horsepower but also improves fuel efficiency and reduces emissions. Here are some key advantages:
- Increased Power Output: Ethanol has a higher octane rating than gasoline, allowing for more aggressive tuning.
- Better Fuel Efficiency: With the right mixture, you can achieve better fuel economy.
- Environmental Benefits: Ethanol burns cleaner than gasoline, leading to reduced emissions.
Choosing the Right Flex Fuel Kit
When selecting a flex fuel kit for your WRX, consider the following factors:
- Compatibility: Ensure the kit is specifically designed for your WRX model and year.
- Installation: Look for kits that come with detailed instructions or professional installation options.
- Support and Warranty: Choose brands that offer customer support and warranty for peace of mind.
Clutch Upgrades for High Horsepower
As you push your WRX beyond 400 horsepower, the stock clutch may struggle to handle the increased power. Upgrading your clutch is essential for maintaining performance and reliability. Here are some popular options:
- Stage 1 Clutch: Suitable for mild power increases, offering better grip without sacrificing daily drivability.
- Stage 2 Clutch: Designed for moderate to high power levels, providing enhanced performance for spirited driving.
- Stage 3 Clutch: Ideal for maximum power applications, but may require a more aggressive driving style.
Installation Considerations
Installing a flex fuel kit and upgrading your clutch can be complex tasks. Here are some considerations to keep in mind:
- Professional Installation: If you’re not comfortable with mechanical work, consider hiring a professional.
- Additional Parts: You may need other components, such as a new flywheel or upgraded master cylinder, depending on your clutch choice.
- Tuning: After installation, a proper tune is crucial to ensure optimal performance and reliability.
Maintaining Your Upgrades
Once you’ve installed your flex fuel kit and upgraded your clutch, regular maintenance is key to ensuring long-lasting performance. Here are some tips:
- Regular Inspections: Check your clutch and fuel system regularly for signs of wear or leaks.
- Fluid Changes: Change your transmission fluid and fuel filter as recommended to keep systems running smoothly.
- Monitor Performance: Keep an eye on your WRX’s performance and address any issues promptly.
Conclusion
Upgrading your WRX with a flex fuel kit and a suitable clutch can significantly enhance performance, especially when targeting 400+ horsepower. By understanding the benefits, choosing the right components, and maintaining them properly, you can enjoy a reliable and powerful driving experience. Whether you’re a daily driver or a track enthusiast, these upgrades can help you achieve your performance goals.
