In this article, we will explore the top power upgrades available for the BRZ FA20 engine, focusing on products from reputable brands like Cobb, Mishimoto, and others.
Understanding the FA20 Engine
The FA20 engine is a 2.0-liter flat-four engine that utilizes a naturally aspirated design. This engine is known for its balance, responsiveness, and relatively low center of gravity. However, to achieve higher horsepower, modifications are essential. The following upgrades will help unlock the full potential of the FA20 engine.
Top Power Upgrades for the BRZ FA20
- Cobb Accessport V3
- Mishimoto Cold Air Intake
- GrimmSpeed Throttle Body Spacer
- Invidia N1 Cat-Back Exhaust
- Turbo Kits
Cobb Accessport V3
The Cobb Accessport V3 is one of the most popular tuning devices for the BRZ FA20. It allows users to reflash the ECU, optimizing engine parameters for increased performance. With pre-loaded maps for various modifications, the Accessport can significantly improve horsepower and torque. Many users report gains of up to 20-30 horsepower with just the Accessport alone.
Mishimoto Cold Air Intake
The Mishimoto Cold Air Intake is designed to improve airflow to the engine, enhancing combustion efficiency. This upgrade not only increases horsepower but also improves throttle response. Users can expect gains of approximately 10-15 horsepower with this intake system. Additionally, it features a washable air filter, ensuring longevity and performance consistency.
GrimmSpeed Throttle Body Spacer
The GrimmSpeed Throttle Body Spacer is a simple yet effective upgrade that can enhance the BRZ’s performance. By creating a plenum effect, it increases airflow into the engine, leading to better throttle response and power gains. While the horsepower increase may be modest, it complements other upgrades well, especially when combined with a tune.
Invidia N1 Cat-Back Exhaust
The Invidia N1 Cat-Back Exhaust system is renowned for its aggressive sound and performance benefits. By reducing back pressure, this exhaust system allows the engine to breathe more freely, resulting in improved horsepower. Users can expect gains of around 10-15 horsepower, along with a more exhilarating driving experience.
Turbo Kits
For those seeking to achieve substantial power increases, turbo kits are an excellent option. Brands like Forced Performance and Full Blown Motorsports offer turbo kits that can elevate the FA20’s horsepower beyond 250. These kits typically include a turbocharger, intercooler, and necessary supporting components. With proper tuning, users can expect power gains of 100+ horsepower, transforming the driving experience.
Supporting Modifications
To maximize the benefits of the aforementioned upgrades, several supporting modifications are advisable. These include:
- Upgraded Fuel Injectors
- High-Performance Fuel Pump
- Aftermarket Engine Management
- Performance Clutch
Upgraded Fuel Injectors
Upgrading fuel injectors ensures that the engine receives the necessary fuel to support increased horsepower. Larger injectors can accommodate higher fuel flow rates, which is crucial when tuning for performance gains.
High-Performance Fuel Pump
A high-performance fuel pump is essential for delivering adequate fuel pressure, especially when using upgraded injectors. This modification prevents fuel starvation during high-demand situations, ensuring consistent performance.
Aftermarket Engine Management
Aftermarket engine management systems provide advanced tuning capabilities, allowing for more precise adjustments to fuel mapping and ignition timing. This ensures the engine runs efficiently and safely at higher power levels.
Performance Clutch
With increased horsepower, a performance clutch is necessary to handle the additional power without slippage. Upgrading to a stronger clutch ensures reliable power transfer to the wheels, enhancing the overall driving experience.
Conclusion
Achieving 250+ horsepower in the Subaru BRZ FA20 is an attainable goal with the right upgrades. By investing in quality products from brands like Cobb and Mishimoto, enthusiasts can significantly enhance their vehicle’s performance. Whether opting for a simple tune or a complete turbo setup, each modification contributes to a more exhilarating driving experience.
