The Subaru BRZ has gained popularity among car enthusiasts for its lightweight design and excellent handling. One of the most effective ways to enhance the performance of the BRZ is by installing a turbo kit. In this article, we will compare two popular turbo sizes: 52mm and 62mm, focusing on their performance impacts and considerations for BRZ owners.
Understanding Turbocharger Sizing
Turbocharger size plays a crucial role in determining the performance characteristics of a vehicle. The size of the turbo affects the boost pressure, power delivery, and overall engine response. When choosing between a 52mm and a 62mm turbo for your BRZ, it is essential to understand how these differences can impact your driving experience.
52mm Turbo Overview
The 52mm turbo is often regarded as a great entry-level option for those looking to increase power without sacrificing too much drivability. Here are some key features of the 52mm turbo:
- Boost Response: The smaller size allows for quicker spool times, resulting in improved throttle response.
- Power Range: Typically supports power levels up to 300-350 horsepower.
- Drivability: Maintains a more linear power delivery, making it suitable for daily driving.
- Installation: Generally easier to install with fewer modifications required.
62mm Turbo Overview
The 62mm turbo is designed for those seeking higher power outputs and performance enhancements. Here are some key features of the 62mm turbo:
- Boost Response: Slightly slower spool times compared to the 52mm but offers higher peak power.
- Power Range: Capable of supporting power levels from 350 to over 500 horsepower.
- Drivability: May exhibit a more aggressive power band, which could affect daily drivability.
- Installation: Often requires more extensive modifications to fit and function properly.
Performance Comparison
When comparing the performance of the 52mm and 62mm turbos, several factors come into play. Below, we break down the differences in performance attributes:
- Horsepower and Torque: The 62mm turbo generally produces higher horsepower and torque figures, which can lead to faster acceleration and higher top speeds.
- Spool Time: The 52mm turbo spools faster, providing boost at lower RPMs, which is beneficial for street driving.
- Power Band: The 62mm turbo has a broader power band, allowing for more power at higher RPMs, making it ideal for track use.
- Heat Management: Larger turbos may generate more heat, requiring additional cooling solutions to maintain optimal engine temperatures.
Considerations for Choosing a Turbo
Choosing the right turbo for your BRZ involves considering several factors beyond just size. Here are some important considerations:
- Driving Style: Determine whether you prioritize daily drivability or high-performance capabilities.
- Power Goals: Set clear power goals to help guide your decision on turbo size.
- Budget: Consider the total cost of the turbo kit, including installation and any necessary supporting modifications.
- Future Upgrades: Think about potential future upgrades and how your turbo choice may affect them.
Conclusion
In summary, both the 52mm and 62mm turbos offer unique advantages for Subaru BRZ owners. The 52mm turbo is ideal for those seeking a balance of performance and drivability, while the 62mm turbo caters to enthusiasts looking for maximum power potential. Ultimately, the choice between the two will depend on individual preferences, driving style, and performance goals.
Regardless of your choice, upgrading to a turbocharged setup can significantly enhance your BRZ’s performance, making it a more thrilling and enjoyable driving experience.
