Evaluating the Costs and Benefits of Forced Induction for Your Brz Fa20 Build

by

The Subaru BRZ, equipped with the FA20 engine, has garnered a loyal following among car enthusiasts. One popular modification is forced induction, which can significantly enhance performance. However, it’s essential to evaluate the costs and benefits before diving into such a project.

Understanding Forced Induction

Forced induction refers to the use of a supercharger or turbocharger to increase the engine’s air intake, allowing for more fuel to be burned and thus increasing power output. This modification can transform the FA20’s performance, but it comes with its own set of challenges and considerations.

Benefits of Forced Induction

There are several advantages to adding forced induction to your BRZ FA20 build:

  • Increased Power Output: The most significant benefit is the substantial increase in horsepower and torque, making your vehicle more exhilarating to drive.
  • Improved Acceleration: With more power, your BRZ will experience improved acceleration, allowing for quicker lap times and a more responsive driving experience.
  • Enhanced Tuning Potential: Forced induction offers more tuning options, enabling you to optimize your engine for various performance metrics.
  • Better Efficiency: When tuned correctly, forced induction can improve fuel efficiency, especially under certain driving conditions.

Costs of Forced Induction

While the benefits are appealing, there are also significant costs associated with forced induction:

  • Initial Investment: The cost of a supercharger or turbocharger kit can be substantial, often ranging from $3,000 to $7,000, depending on the brand and model.
  • Installation Costs: Professional installation is recommended, which can add another $1,000 to $2,000 to your total costs.
  • Increased Maintenance: Forced induction can lead to increased wear and tear on engine components, necessitating more frequent maintenance and potential repairs.
  • Potential for Engine Failure: If not installed or tuned correctly, forced induction can lead to engine failure, resulting in costly repairs.

Factors to Consider Before Forced Induction

Before deciding to add forced induction to your BRZ FA20, consider the following factors:

  • Your Driving Goals: Determine what you want to achieve with your build. Are you looking for daily drivability, track performance, or a mix of both?
  • Budget: Assess your budget not only for the initial investment but also for ongoing maintenance and potential repairs.
  • Experience Level: Ensure you have the necessary knowledge or access to professionals who can help with the installation and tuning.
  • Local Regulations: Check local emissions and modification laws to ensure that your forced induction setup complies with regulations.

There are several forced induction options available for the BRZ FA20. Here are a few popular choices:

  • Turbocharger Kits: Brands like GrimmSpeed and Precision Turbo offer turbo kits that can provide significant power gains.
  • Supercharger Kits: Companies such as Edelbrock and Vortech provide supercharger kits that deliver immediate power and torque.
  • Hybrid Kits: Some enthusiasts opt for hybrid setups that combine elements of both turbocharging and supercharging for unique performance characteristics.

Conclusion

Evaluating the costs and benefits of forced induction for your BRZ FA20 build requires careful consideration. While the potential for increased power and performance is enticing, the associated costs and risks must not be overlooked. By weighing these factors, you can make an informed decision that aligns with your goals and budget.
