The Subaru BRZ, equipped with the FA20 engine, has gained a reputation as a fun and agile sports car. However, enthusiasts often seek to enhance its performance, aiming for over 300 horsepower. This article delves into the costs, parts required, and real-world track results of building a 300+ HP BRZ FA20.

Understanding the FA20 Engine

The FA20 engine is a naturally aspirated 2.0-liter flat-four engine known for its low center of gravity and lightweight design. While it delivers a respectable amount of power stock, many owners look to modify it for increased performance.

Cost Breakdown for Building 300+ HP

Building a 300+ HP BRZ FA20 requires significant investment. Below is a breakdown of the potential costs involved:

  • Engine Management System: $1,000 – $2,500
  • Turbocharger Kit: $3,000 – $6,000
  • Upgraded Fuel System: $500 – $1,500
  • Exhaust System: $500 – $1,500
  • Intercooler: $300 – $1,000
  • Performance Tuning: $500 – $1,000
  • Miscellaneous Parts (pulleys, hoses, etc.): $500 – $1,000

Total estimated cost: $7,800 – $14,500 depending on the parts and labor involved.

Essential Parts for the Build

To achieve over 300 horsepower, several key modifications are necessary. Here’s a list of essential parts for the build:

  • Turbocharger Kit: A quality turbo kit is crucial for increasing airflow and boosting power.
  • Upgraded Fuel Injectors: Higher flow injectors are needed to support the increased fuel demands.
  • ECU Tuning: A custom tune is essential to optimize performance and ensure reliability.

  • Exhaust System: A free-flowing exhaust system reduces back pressure and enhances power output.
  • Performance Clutch: An upgraded clutch is necessary to handle the increased power and torque.

Real-World Track Results

After completing the build, many owners take their BRZs to the track to test the results. Here are some real-world outcomes:

  • Quarter-Mile Times: Many modified BRZs report quarter-mile times in the low 12-second range.
  • Track Lap Times: On road courses, lap times can improve significantly, often by several seconds compared to stock.
  • Driver Feedback: Enthusiasts often report increased throttle response and overall driving enjoyment.

Conclusion

Building a 300+ HP BRZ FA20 is an exciting project that can yield impressive results on the track. With careful planning, the right parts, and a solid budget, enthusiasts can transform their BRZ into a high-performance machine. Always remember to consider the balance between performance and reliability to enjoy the full potential of your build.
