The Subaru WRX is a beloved vehicle among car enthusiasts, particularly for those looking to enhance performance. One of the most effective ways to increase horsepower is through turbo upgrades, especially when converting to E85 fuel. This article explores the best turbo upgrades for WRX E85 conversions, focusing on achieving over 450 horsepower with a VF52/VF48 hybrid turbo.
Understanding E85 Fuel
E85 fuel is a blend of 85% ethanol and 15% gasoline. It has a higher octane rating than regular gasoline, allowing for more aggressive tuning and improved performance. However, it also requires specific modifications to your vehicle to maximize its benefits.
Benefits of Upgrading to a VF52/VF48 Hybrid Turbo
The VF52 and VF48 turbos are popular choices for WRX enthusiasts. By combining these two turbos into a hybrid setup, you can achieve significant power gains. Here are some benefits of this upgrade:
- Increased Power Output: A hybrid turbo can push your WRX to over 450 horsepower.
- Improved Boost Response: The hybrid design enhances spool time, providing quicker throttle response.
- Enhanced Efficiency: More efficient airflow can lead to better fuel economy under certain conditions.
Key Components for an E85 Conversion
Before upgrading to a VF52/VF48 hybrid turbo, several components must be addressed to ensure your WRX can handle the increased power and E85 fuel. Here are the key components to consider:
- Fuel System Upgrade: Ensure your fuel pump and injectors can handle E85. Larger injectors are essential for proper fuel delivery.
- ECU Tuning: A proper tune is necessary to optimize performance and ensure the engine runs efficiently on E85.
- Intercooler Upgrade: A larger intercooler will help manage the increased heat generated by higher boost levels.
- Exhaust System: An upgraded exhaust system can improve airflow and reduce back pressure, enhancing performance.
Choosing the Right VF52/VF48 Hybrid Turbo
When selecting a hybrid turbo, it’s essential to consider various factors to ensure optimal performance. Here are some tips for choosing the right turbo:
- Turbo Size: Consider the compressor and turbine size for achieving your desired power level.
