Fa20 Power Gains from Upgrading the Limited-slip Differential for Better Handling and Power Transfer

The FA20 engine, known for its performance and efficiency, can benefit significantly from upgrading the limited-slip differential (LSD). This upgrade enhances handling and power transfer, making it a popular modification among enthusiasts.

Understanding the Limited-Slip Differential

A limited-slip differential is a crucial component in a vehicle’s drivetrain. It allows for better traction and power distribution between the wheels, particularly during acceleration and cornering. By upgrading to a high-performance LSD, drivers can experience notable improvements in handling and power transfer.

Benefits of Upgrading the Limited-Slip Differential

  • Improved Traction: An upgraded LSD provides better grip, especially in slippery conditions.
  • Enhanced Cornering: The LSD allows for more controlled and stable cornering by distributing power to the wheel with the most traction.
  • Increased Power Transfer: More efficient power transfer from the engine to the wheels results in quicker acceleration.
  • Better Stability: An LSD contributes to overall vehicle stability, reducing the risk of oversteer or understeer.

Types of Limited-Slip Differentials

  • Clutch-Type LSD: Utilizes clutch plates to manage power distribution. It offers a balance between street and track performance.
  • Helical LSD: Uses gears to provide a smooth transfer of power. It’s quieter and requires less maintenance.
  • Viscous LSD: Employs a silicone-based fluid to manage power distribution. It’s effective but may not be as responsive as other types.

Choosing the Right LSD for Your FA20

When selecting a limited-slip differential for your FA20, consider the following factors:

  • Driving Style: Choose an LSD that fits your driving habits, whether for daily driving, track days, or off-road adventures.
  • Power Goals: Match the LSD’s capabilities with your engine’s power output and performance goals.
  • Budget: Determine how much you’re willing to invest in the upgrade, as prices can vary significantly.

Installation Process

Installing a limited-slip differential requires mechanical expertise. Here’s a general overview of the installation process:

  • Preparation: Gather necessary tools and parts, including the new LSD and any additional hardware.
  • Remove the Old Differential: Drain the fluid, remove the driveshaft, and detach the differential from the rear axle.
  • Install the New LSD: Follow the manufacturer’s instructions to install the new differential securely.
  • Reassemble and Test: Reattach all components, refill with differential fluid, and conduct a test drive to ensure proper functioning.

Performance Improvements After Upgrading

After upgrading to a limited-slip differential, drivers often report significant performance improvements:

  • Quicker Acceleration: Enhanced power transfer leads to faster acceleration off the line.
  • Better Handling: Improved traction during cornering results in a more responsive driving experience.
  • Increased Confidence: Drivers feel more secure in their vehicle’s handling characteristics, especially in challenging conditions.

Conclusion

Upgrading the limited-slip differential in an FA20 engine can provide substantial benefits in handling and power transfer. By understanding the types of LSDs available and their respective advantages, drivers can make informed decisions that enhance their driving experience.
