The Subaru BRZ, known for its lightweight design and balanced handling, has become a favorite among car enthusiasts. However, many owners seek to enhance its performance. In this article, we will explore how to boost the BRZ FA20 engine’s power from stock to an impressive 280 horsepower using a Vortech supercharger and other supporting modifications.
Understanding the FA20 Engine
The FA20 engine is a 2.0-liter flat-four engine that powers the BRZ. It delivers a respectable amount of horsepower and torque, but many drivers desire more power for track days or spirited driving. The key to achieving this power increase lies in forced induction and proper supporting mods.
Choosing the Vortech Supercharger
The Vortech supercharger is a popular choice for BRZ owners looking to increase horsepower. This centrifugal supercharger is known for its efficiency and reliability. Here are some reasons why it’s a great option:

Supporting Modifications
While the Vortech supercharger provides the primary boost in power, several supporting modifications are necessary to ensure the engine runs smoothly and reliably. Here are some essential mods to consider:
- Upgraded Fuel Injectors: To support the increased airflow, higher flow fuel injectors are essential.
- High-Performance Fuel Pump: A high-performance fuel pump ensures adequate fuel supply under boost.
- Intercooler: An upgraded intercooler helps to lower intake temperatures, improving performance and reliability.
- Exhaust System: A free-flowing exhaust system reduces back pressure and enhances sound.
- Tune: A proper ECU tune is crucial to optimize performance and prevent engine damage.
Installation Process
Installing the Vortech supercharger and supporting mods requires mechanical knowledge and the right tools. Here’s a general overview of the installation process:
- Preparation: Gather all necessary tools and parts. Ensure the vehicle is on a stable surface.

- Tuning: Once everything is installed, take the car to a professional tuner for proper calibration.
Expected Performance Gains
After completing the installation and tuning process, BRZ owners can expect significant performance gains. Here’s what you can typically anticipate:
- Horsepower: Increase from stock (~200 hp) to approximately 280 hp.
- Torque: Torque figures can also see a notable increase, enhancing overall drivability.
- Acceleration: Improved acceleration times, making the BRZ more exhilarating to drive.
Maintaining Your Modified BRZ
Once your BRZ is modified, regular maintenance becomes even more critical. Here are some tips to keep your vehicle running smoothly:
- Regular Oil Changes: Use high-quality synthetic oil and change it more frequently than stock recommendations.
- Monitor Boost Levels: Keep an eye on your boost levels to avoid potential issues.
- Check for Leaks: Regularly inspect for any fuel or oil leaks around the supercharger and supporting mods.
- Scheduled Maintenance: Adhere to a strict maintenance schedule, including checking the condition of the supercharger and supporting parts.
