The Subaru WRX is a popular choice among car enthusiasts, especially for those looking to boost performance through modifications. One of the most significant upgrades is converting to E85 fuel, which offers higher octane levels and improved combustion efficiency. However, this conversion comes with a cost. In this article, we will break down the costs associated with a WRX E85 conversion, focusing on the turbo, fuel system, and tuning expenses.
Understanding E85 Conversion
E85 is a blend of 85% ethanol and 15% gasoline, providing several advantages for performance vehicles. It allows for more aggressive tuning and can lead to increased horsepower and torque. However, converting your WRX to run on E85 requires specific modifications to the fuel system and tuning adjustments.
Cost Breakdown of E85 Conversion
1. Turbo Upgrade Costs
The turbocharger is a critical component when converting to E85, as it needs to be capable of handling the increased fuel flow and boost levels. Here’s what to consider:
- Aftermarket Turbocharger: $1,500 – $3,500
- Installation Costs: $500 – $1,000
- Supporting Mods (intercooler, exhaust): $1,000 – $2,000
In total, expect to spend between $3,000 and $6,500 for a quality turbo upgrade that supports E85 conversion.
2. Fuel System Upgrades
Running E85 requires a more robust fuel system to handle the increased fuel flow and different properties of ethanol. Key components include:
- Fuel Pump: $200 – $500
- Fuel Injectors: $400 – $800
- Fuel Lines and Fittings: $100 – $300
- Fuel Pressure Regulator: $100 – $200
Overall, you can expect to invest between $900 and $1,800 for the necessary fuel system upgrades.
3. Tuning Costs
Proper tuning is essential for maximizing performance and ensuring engine safety after converting to E85. Tuning costs can vary based on the method you choose:
- ECU Reflash: $300 – $600
- Dyno Tuning: $400 – $800
- Custom Tune: $500 – $1,200
Depending on your tuning choice, expect to spend between $300 and $1,200.
Total Estimated Costs
When combining all the costs associated with the turbo upgrade, fuel system, and tuning, here is a summary:
- Turbo Upgrade: $3,000 – $6,500
- Fuel System Upgrades: $900 – $1,800
- Tuning: $300 – $1,200
The total estimated cost for a WRX E85 conversion ranges from approximately $4,200 to $9,500. This range can vary based on the specific parts chosen, labor costs, and any additional modifications made.
Conclusion
Converting your WRX to run on E85 can provide significant performance benefits, but it is essential to budget accordingly. By understanding the costs associated with the turbo upgrade, fuel system modifications, and tuning, you can make informed decisions that align with your performance goals. Always remember to consult with professionals to ensure that your modifications are done correctly and safely.
