Best Size Turbo for Your Brz: 58mm Vs62mm Garrett Options for Optimal Power Gains

The Subaru BRZ is a popular choice for car enthusiasts looking to enhance their driving experience. One of the most effective ways to boost performance is by upgrading the turbocharger. In this article, we will explore the best size turbo for your BRZ, focusing on the 58mm and 62mm Garrett options. Both sizes offer unique advantages, and understanding these can help you make an informed decision.

Understanding Turbocharger Sizing

Turbocharger size is crucial in determining the power output and response of your vehicle. The size of the turbocharger affects the amount of air and fuel mixture that can be forced into the engine, influencing overall performance. When considering a turbo upgrade for your BRZ, two popular options are the 58mm and 62mm Garrett turbochargers.

58mm Garrett Turbocharger

The 58mm Garrett turbocharger is a great option for those looking for a balance between power and drivability. This size is often favored for street use, as it provides quicker spool times and better low-end torque.

Advantages of the 58mm Turbo

  • Faster Spool Time: The smaller size allows for quicker boost response, making it ideal for daily driving.
  • Improved Low-End Torque: The 58mm turbo enhances low-end power, providing a more enjoyable driving experience in urban settings.
  • Better Fuel Efficiency: With a smaller turbo, you may experience improved fuel economy compared to larger turbos.

62mm Garrett Turbocharger

On the other hand, the 62mm Garrett turbocharger is designed for those seeking maximum power output. This option is suitable for enthusiasts who prioritize performance and are willing to sacrifice some drivability.

Advantages of the 62mm Turbo

  • Higher Power Potential: The larger size allows for greater airflow, resulting in increased horsepower and torque at higher RPMs.
  • Enhanced Performance: Ideal for track use or high-performance builds where maximum power is the goal.
  • Better Top-End Power: The 62mm turbo shines in high-speed scenarios, making it perfect for racing environments.

Comparing the Two Options

When deciding between the 58mm and 62mm Garrett turbos for your BRZ, consider the following factors:

  • Driving Style: If you primarily drive in the city or prefer a balanced setup, the 58mm may be the better choice. For those focused on track performance, the 62mm could be more suitable.
  • Power Goals: Determine how much power you want to achieve. The 62mm is better for high horsepower builds, while the 58mm is sufficient for moderate increases.
  • Budget: Larger turbos may require additional modifications, which can increase overall costs. Consider your budget when making a decision.

Installation Considerations

Upgrading your turbocharger involves more than just swapping out parts. Here are some installation considerations:

  • Supporting Mods: Depending on the turbo size, you may need to upgrade fuel injectors, intercoolers, and exhaust systems to support the increased airflow.
  • Tuning: A proper tune is essential after installing a new turbo to ensure optimal performance and reliability.
  • Professional Installation: Consider hiring a professional to install your turbo, especially if you are not experienced with engine modifications.

Conclusion

Choosing the best size turbo for your BRZ ultimately depends on your driving preferences and performance goals. The 58mm Garrett turbo offers a great balance for daily driving, while the 62mm turbo is perfect for those seeking maximum power. Assess your needs, consider the installation process, and you will be well on your way to enhancing your BRZ’s performance.
