The Subaru WRX is a popular choice among car enthusiasts, especially for those looking to enhance performance through modifications. One of the most effective ways to boost power and efficiency is by converting to E85 fuel. However, to make this conversion successful, you need to upgrade your fuel system. In this article, we will explore budget-friendly options for injectors, pumps, and lines, all under $1000.
Understanding E85 Fuel
E85 is a blend of 85% ethanol and 15% gasoline. It has a higher octane rating compared to standard gasoline, which allows for more aggressive tuning and increased horsepower. However, the use of E85 requires specific modifications to the fuel system due to its different properties, such as lower energy content and higher flow requirements.
Key Components for E85 Conversion
- Fuel Injectors
- Fuel Pump
- Fuel Lines
1. Fuel Injectors
Fuel injectors are crucial for delivering the right amount of fuel to the engine. For an E85 conversion, you need injectors that can handle higher flow rates. Here are some budget options:
- DeatschWerks DW200 650cc Injectors: These injectors provide a great balance between cost and performance, with a flow rate suitable for E85 applications.
- Injector Dynamics ID1050X: Known for their reliability and performance, these injectors are a bit pricier but worth considering for serious builds.
- FIC (Fuel Injector Clinic) 1000cc Injectors: A solid choice for those looking to push the limits without breaking the bank.
2. Fuel Pump
The fuel pump is another essential component that needs upgrading for E85. A higher flow pump ensures that your engine receives enough fuel under high demand conditions. Here are some budget-friendly options:
- Walbro 255lph Fuel Pump: This is a popular choice among WRX owners, known for its reliability and affordability.
- DeatschWerks DW65c: A compact and efficient pump that works well for E85 conversions.
- Airtex E8529S: A budget option that still provides decent performance for E85 applications.
3. Fuel Lines
When converting to E85, it’s crucial to ensure that your fuel lines are compatible with ethanol. Standard rubber lines may degrade over time, leading to leaks. Consider these options:
- PTFE Fuel Line: This material is highly resistant to ethanol and provides excellent durability.
- AN Stainless Steel Braided Lines: Not only do they look great, but they also offer excellent resistance to fuel degradation.
- Fuel Hose Kits: Many aftermarket kits are available that include everything needed for a complete line upgrade.
Cost Breakdown
Here’s a rough estimate of what you can expect to spend on each component for your E85 conversion:
- Fuel Injectors: $300 – $500
- Fuel Pump: $100 – $200
- Fuel Lines: $50 – $150
When combined, these upgrades can typically be achieved for under $1000, making it a feasible option for many WRX enthusiasts.
Installation Tips
Installing these components requires some mechanical knowledge. Here are some tips to ensure a smooth installation:
- Read the Manuals: Always refer to the installation manuals provided with your components.
- Use Proper Tools: Make sure you have the necessary tools, including wrenches, pliers, and safety equipment.
- Check for Leaks: After installation, double-check all connections for leaks before starting the engine.
Conclusion
Upgrading your WRX fuel system for E85 conversion is a smart move for performance enthusiasts. With careful selection of budget-friendly injectors, pumps, and lines, you can achieve significant gains without exceeding your budget. Always ensure that you follow installation best practices for a successful conversion.
