The Toyota GR86 is a popular sports coupe known for its lightweight design and engaging driving experience. As enthusiasts look to enhance performance, the addition of a turbo kit has become a common modification. In this article, we will explore the real-world results of testing the Toyota GR86 with a turbo kit, focusing on power gains and daily driveability.
Understanding the Toyota GR86
The Toyota GR86 is part of the Subaru-Toyota collaboration, sharing its platform with the Subaru BRZ. Known for its rear-wheel-drive layout and balanced handling, the GR86 offers a naturally aspirated 2.4-liter flat-four engine. The stock power output is around 228 horsepower and 184 lb-ft of torque, providing a solid foundation for performance enthusiasts.
The Benefits of a Turbo Kit
A turbo kit can significantly enhance the performance of the GR86 by forcing more air into the engine, resulting in greater power output. Here are some key benefits:
- Increased Horsepower: Turbocharging can elevate the power output significantly, often exceeding 300 horsepower.
- Improved Torque: Turbo kits typically enhance torque availability across a wider RPM range.
- Better Throttle Response: A well-tuned turbo setup can improve throttle response, making the car feel more lively.
- Enhanced Driving Experience: The power increase transforms the driving dynamics, making it more exhilarating.
Testing Methodology
To evaluate the performance of the GR86 with a turbo kit, we conducted a series of tests, including dyno runs and real-world driving scenarios. The testing process involved:
- Baseline Dyno Testing: Measuring the stock power output before modifications.
- Installation of Turbo Kit: Installing a reputable turbo kit designed for the GR86.
- Tuning: Optimizing the engine management system for the new setup.
- Post-Installation Dyno Testing: Measuring the power gains after installation.
- Real-World Driving: Evaluating daily driveability and performance in various conditions.
Power Gains from the Turbo Kit
After installing the turbo kit and completing the tuning process, we conducted a series of dyno runs to assess the power gains. The results were impressive:
- Baseline Power: 228 horsepower and 184 lb-ft of torque.
- Post-Turbo Power: 320 horsepower and 290 lb-ft of torque.
- Peak Power Increase: A gain of 92 horsepower and 106 lb-ft of torque.
This significant increase in power transforms the GR86 into a formidable performance machine, allowing for quicker acceleration and a more engaging driving experience.
Daily Driveability Assessment
While power gains are essential, daily driveability is equally important for a sports car. We evaluated how the turbocharged GR86 performed in everyday scenarios:
- Throttle Response: The turbocharged engine provided a responsive throttle, making city driving enjoyable.
- Low-End Torque: Enhanced low-end torque made for smoother starts and easier navigation in traffic.
- Fuel Efficiency: Despite the power increase, fuel efficiency remained reasonable, especially during highway cruising.
- Sound and Comfort: The turbo kit did not significantly alter the cabin noise levels, maintaining the GR86’s comfortable ride.
Conclusion
Testing the Toyota GR86 with a turbo kit revealed substantial power gains and maintained daily driveability. With an increase to over 320 horsepower, the GR86 becomes an exhilarating sports car without sacrificing comfort or usability. For enthusiasts looking to enhance their driving experience, a turbo kit is a worthy consideration that delivers real-world results.
