The A90 Toyota Supra has quickly become a favorite among car enthusiasts, especially those looking to modify their vehicles for enhanced performance. With its powerful B58 engine, the Supra has the potential to reach impressive horsepower figures. In this article, we will explore how to achieve over 600 horsepower using HKS exhaust systems and COBB tuning.
Understanding the B58 Engine
The B58 engine, a 3.0-liter inline-six, is known for its smooth power delivery and robust performance. It features a twin-scroll turbocharger, which contributes to its quick spool and responsiveness. This engine is the foundation for many modifications that can elevate its power output significantly.
Why Upgrade to HKS Exhaust?
Upgrading to an HKS exhaust system is a popular modification among Supra owners. The HKS exhaust is designed to improve exhaust flow, reduce back pressure, and enhance the sound of the vehicle. Here are some key benefits:
- Improved Performance: The HKS exhaust allows for better exhaust flow, which can lead to increased horsepower and torque.
- Weight Reduction: Aftermarket exhaust systems are often lighter than stock, improving the vehicle’s overall weight distribution.
- Enhanced Sound: HKS exhaust systems produce a more aggressive and sporty sound, enhancing the driving experience.
COBB Tuning: Unlocking the B58’s Potential
COBB Tuning is a well-known name in the performance tuning industry. Their Accessport is a powerful tool for optimizing engine performance. Here’s how COBB tuning can help you achieve over 600 horsepower:
- Customizable Maps: COBB offers various tuning maps tailored for different modifications, including those with an HKS exhaust.
- Real-Time Monitoring: The Accessport allows you to monitor engine parameters in real-time, ensuring optimal performance and safety.
- Easy Installation: Installing the Accessport is straightforward, making it accessible for both beginners and experienced tuners.
Steps to Achieve 600+ HP
Achieving over 600 horsepower in your A90 Supra requires a combination of the right modifications and tuning. Here’s a step-by-step guide:
- Step 1: Install the HKS exhaust system to improve exhaust flow.
- Step 2: Use the COBB Accessport to upload a performance map suitable for your modifications.
- Step 3: Consider additional upgrades such as a larger intercooler, upgraded fuel injectors, and a high-flow intake system.
- Step 4: Perform a dyno tune to ensure your vehicle is running efficiently and safely at higher horsepower levels.
Additional Modifications for Enhanced Performance
While the HKS exhaust and COBB tuning are crucial for reaching 600+ horsepower, there are several other modifications that can further enhance your Supra’s performance:
- Upgraded Turbocharger: Consider a larger turbo for increased airflow and power potential.
- High-Performance Fuel Pump: An upgraded fuel pump ensures that your engine receives adequate fuel for high horsepower levels.
- ECU Upgrades: Additional ECU modifications can help manage the increased power and improve throttle response.
Conclusion
Modifying your A90 Supra B58 to achieve over 600 horsepower is an exciting journey that combines the right parts and tuning. With the HKS exhaust and COBB tuning, you can unlock the full potential of your vehicle, making it a true powerhouse on the road. Always remember to follow best practices for tuning and modifications to ensure your Supra remains reliable and performs at its best.
