The A90 Supra has captured the hearts of car enthusiasts with its sleek design and impressive performance. However, for those looking to push the limits of this sports car, upgrading the drivetrain components is essential, especially when aiming for 500+ horsepower. In this article, we will explore clutch and transmission upgrades that can help you achieve that goal while ensuring reliability and performance.
Understanding the A90 Supra’s Drivetrain
The A90 Supra is equipped with a robust drivetrain that includes a powerful inline-six engine and an 8-speed automatic transmission. However, to handle increased horsepower and torque, certain components must be upgraded to prevent failure and enhance performance.
Clutch Upgrades for Enhanced Performance
Upgrading the clutch is one of the most critical aspects of strengthening the A90 Supra’s drivetrain. The stock clutch may not handle the increased power effectively, leading to slippage and reduced performance.
Choosing the Right Clutch Kit
When selecting a clutch kit for your A90 Supra, consider the following options:
- Performance Clutch Kits: Designed for higher horsepower applications, these kits often feature upgraded materials for better heat resistance.
- Single vs. Twin Disc Clutches: Twin disc clutches can handle more power but may require more effort to operate, while single disc options are more street-friendly.
- Clutch Brands: Look for reputable brands like ACT, Clutch Masters, or Exedy, known for their quality and performance.
Installation Considerations
Proper installation is crucial for the longevity and performance of your new clutch. Here are some key points to keep in mind:
- Professional Installation: If you are not experienced with clutch replacements, consider hiring a professional to ensure everything is done correctly.
- Break-In Period: Follow the manufacturer’s recommendations for breaking in the new clutch to avoid premature wear.
Transmission Upgrades for Increased Durability
The transmission in the A90 Supra is designed to handle a significant amount of power, but with upgrades, it can be further enhanced to cope with the demands of 500+ horsepower.
Upgrading the Transmission Fluid
One of the simplest upgrades is switching to high-performance transmission fluid. This can improve shifting performance and reduce heat buildup.
Aftermarket Transmission Options
If you plan to push your A90 Supra to its limits, consider aftermarket transmission options that offer greater durability:
- Reinforced Transmission Cases: These provide additional strength to withstand higher power levels.
- Upgraded Torque Converters: A higher-stall torque converter can improve acceleration and responsiveness.
- Transmission Control Modules: Upgraded TCMs can optimize shift points for performance driving.
Transmission Maintenance Tips
To ensure your upgraded transmission remains in top condition, follow these maintenance tips:
- Regular Fluid Changes: Change the transmission fluid at recommended intervals to maintain performance.
- Monitor for Leaks: Regularly check for any signs of fluid leaks around the transmission.
- Check for Error Codes: Use a diagnostic tool to monitor for any transmission-related error codes.
Final Thoughts on Upgrading the A90 Supra’s Drivetrain
Upgrading the clutch and transmission of your A90 Supra is essential for those looking to achieve 500+ horsepower while maintaining reliability. By carefully selecting the right components and ensuring proper installation and maintenance, you can enhance the performance of your Supra and enjoy a thrilling driving experience.
