The Subaru WRX is a beloved performance car known for its rally heritage and impressive turbocharged engines. For enthusiasts looking to maximize power, upgrading the turbocharger is one of the most effective modifications. In this article, we will explore the best turbo upgrades for WRX built engines, focusing on the FP Green, VF52, and other options that can help unleash your engine’s full potential.
Understanding Turbocharger Upgrades
Turbochargers play a crucial role in enhancing engine performance by forcing more air into the combustion chamber. This allows for more fuel to be burned, resulting in increased power output. However, not all turbos are created equal, and choosing the right one for your WRX built engine can make a significant difference.
FP Green Turbo
The FP Green turbo is a popular choice among WRX enthusiasts looking for a balance between power and reliability. This turbo is known for its ability to produce substantial horsepower while maintaining good spool characteristics. Here are some key features:
- Power Output: Capable of producing 400+ horsepower.
- Spool Time: Quick spool for responsive acceleration.
- Durability: Built with high-quality materials for longevity.
The FP Green is especially suited for those who want to push their WRX to higher power levels without sacrificing drivability.
VF52 Turbo
The VF52 turbo is another excellent option for WRX built engines, particularly for those looking for a more cost-effective upgrade. This turbo is known for its reliability and performance, making it a great choice for both daily drivers and performance builds.
- Power Output: Typically supports up to 300-350 horsepower.
- Response: Excellent low-end torque and quick spool.
- Compatibility: Direct bolt-on for many WRX models.
The VF52 is ideal for those who want a significant boost in performance without going to extreme power levels.
Other Turbo Options
While the FP Green and VF52 are standout choices, there are several other turbo upgrades worth considering for WRX built engines:
- Garrett GTX2867R: Known for its efficiency and high power potential, this turbo can support over 500 horsepower.
- Blouch 20G: A popular choice for those seeking a balance of power and spool time, capable of around 400 horsepower.
- FP Black: For those looking for extreme power, the FP Black can exceed 600 horsepower with the right supporting mods.
Each of these turbos has its unique characteristics, making them suitable for different performance goals and driving styles.
Supporting Modifications
Upgrading your turbocharger is just one part of the equation when it comes to maximizing power in your WRX. To truly unlock the potential of your new turbo, consider the following supporting modifications:
- Upgraded Fuel System: Ensure your engine is receiving enough fuel to match the increased air flow.
- Performance Intercooler: A larger intercooler helps keep intake temperatures down, improving power and reliability.
- ECU Tuning: Proper tuning is essential to optimize performance and ensure the engine runs smoothly with the new turbo.
These modifications work in tandem with your turbo upgrade to create a well-rounded performance package.
Conclusion
Upgrading the turbocharger on your WRX built engine is one of the most effective ways to enhance performance. Whether you choose the FP Green for its high power potential, the VF52 for its reliability, or one of the other options available, ensuring you have the right supporting modifications will help you achieve your performance goals. With the right setup, your WRX can deliver exhilarating power and driving excitement.
