The Subaru BRZ has gained a reputation for its lightweight design, agile handling, and engaging driving experience. However, many enthusiasts seek to enhance performance through turbocharging. This article compares two popular options: the Cobb Tuning Stage 2 turbo kit and the Subaru OEM turbo. We will evaluate their performance, installation, and overall value to help you determine which is best for your BRZ.
Understanding Turbocharging
Turbocharging is a method of forced induction that increases an engine’s efficiency and power output. By using exhaust gases to spin a turbine, a turbocharger compresses incoming air, allowing for a denser air-fuel mixture. This results in more power without significantly increasing engine size or weight.
Cobb Tuning Stage 2 Turbo Kit
The Cobb Tuning Stage 2 turbo kit is designed to maximize the performance of the BRZ. It includes a larger turbocharger, upgraded intercooler, and all necessary hardware for installation. Here are some key features:
- Larger Turbocharger: Increases airflow and power output.
- Intercooler Upgrade: Reduces intake temperatures for better performance.
- Complete Installation Kit: All necessary components included for a straightforward install.
Performance Metrics
With the Cobb Stage 2 kit, BRZ owners can expect significant performance gains. Typical horsepower increases range from 50 to 80 horsepower, depending on supporting modifications and tuning. The torque curve also becomes more robust, providing a more enjoyable driving experience.
Installation Process
The installation of the Cobb Tuning Stage 2 kit requires moderate mechanical skills. While it is designed to be user-friendly, some experience with automotive work is beneficial. The process typically takes around 6-8 hours, depending on the tools available and familiarity with the vehicle.
Subaru OEM Turbo
The Subaru OEM turbo option is another route for enhancing the BRZ’s performance. This turbo is designed specifically for the vehicle and offers a reliable, factory-approved solution. Here are some of its characteristics:
- Factory Fitment: Designed to work seamlessly with the BRZ’s engine.
- Reliability: Built to Subaru’s standards, ensuring durability.
- Warranty: Typically comes with a manufacturer warranty for peace of mind.
Performance Metrics
The Subaru OEM turbo provides a more modest increase in horsepower compared to the Cobb kit, generally adding around 30-50 horsepower. However, it maintains a smooth power delivery and is ideal for those who prefer a more factory-like driving experience.
Installation Process
Installation of the Subaru OEM turbo is relatively straightforward, especially for those familiar with factory components. It typically requires 4-6 hours and can be performed by a skilled DIYer or a professional mechanic.
Comparative Analysis
When comparing the Cobb Tuning Stage 2 kit to the Subaru OEM turbo, several factors come into play:
- Performance: Cobb provides higher horsepower and torque gains.
- Installation: Subaru OEM is generally easier and quicker to install.
- Cost: Cobb kits tend to be more expensive due to additional components.
- Reliability: Subaru OEM parts are backed by the manufacturer, ensuring quality.
Conclusion
Choosing between the Cobb Tuning Stage 2 turbo kit and the Subaru OEM turbo depends on your performance goals and preferences. If you seek maximum power and are comfortable with a more complex installation, the Cobb kit is an excellent choice. However, if you prefer reliability and a factory feel, the Subaru OEM turbo may be the better option. Consider your driving style, budget, and long-term goals when making your decision.
