Upgrading the A80 Supra’s Drivetrain: Clutches, Differentials, and Transmission for Improved Power Handling

by

The A80 Supra, a legendary sports car, is known for its impressive performance and tuning potential. When it comes to maximizing power handling, upgrading the drivetrain components such as clutches, differentials, and transmissions is essential. This article delves into the best practices for enhancing the A80 Supra’s drivetrain for improved performance.

Understanding the A80 Supra Drivetrain

The A80 Supra was produced from 1993 to 2002 and is celebrated for its robust 2JZ engine. However, to fully harness the engine’s power, the drivetrain must be capable of handling increased torque and horsepower. Key components include the clutch, differential, and transmission.

Upgrading the Clutch

The clutch is a critical component that connects the engine to the transmission. Upgrading the clutch can significantly improve power transfer and overall performance.

Choosing the Right Clutch

When selecting a clutch for the A80 Supra, consider the following:

  • Material: Options include organic, ceramic, and metallic clutches, each offering different levels of grip and wear characteristics.
  • Pressure Plate: A higher clamping force can lead to better power handling but may result in a heavier pedal feel.
  • Size: Ensure compatibility with the stock flywheel or consider an aftermarket flywheel for improved performance.

Some popular clutch upgrades for the A80 Supra include:

  • ACT Heavy Duty Clutch
  • Exedy Stage 1 Clutch Kit
  • Clutch Masters FX400 Clutch

Upgrading the Differential

The differential plays a crucial role in distributing power to the wheels. A performance differential can enhance traction and stability, especially during aggressive driving.

Types of Differentials

When upgrading the differential, consider the following types:

  • Open Differential: Provides power to the wheel with the least resistance, not ideal for performance.
  • Limited Slip Differential (LSD): Distributes power to both wheels, improving traction during acceleration.
  • Torque Vectoring Differential: Offers the best performance by distributing power based on traction needs.

Consider the following differential upgrades for the A80 Supra:

  • OEM Toyota LSD
  • Kaaz 1.5-Way LSD
  • OS Giken Super Lock LSD

Upgrading the Transmission

The transmission is the backbone of the drivetrain, responsible for gear shifting and power delivery. Upgrading the transmission can enhance shifting speed and reliability.

Transmission Options

When considering transmission upgrades for the A80 Supra, you have several options:

  • Stock 6-Speed Manual: A reliable option that can handle moderate power increases.
  • Aftermarket Sequential Transmission: Provides faster shifts and is suitable for high-performance applications.
  • Automatic Transmission Upgrade: Consider a performance-built automatic for easier daily driving with good power handling.

Some recommended transmission upgrades for the A80 Supra include:

  • Getrag 6-Speed Manual Transmission
  • Quafe Sequential Gearbox
  • Built Automatic Transmission from Level 10

Conclusion

Upgrading the A80 Supra’s drivetrain components is essential for maximizing performance and power handling. By focusing on the clutch, differential, and transmission, you can ensure your Supra can handle increased power while offering an exhilarating driving experience.
