Clutch and Transmission Upgrades for the Gt-r Vr38dett: Handling Increased Power Safely

by

The Nissan GT-R VR38DETT is renowned for its impressive performance capabilities, but as enthusiasts look to increase power through modifications, it becomes essential to upgrade the clutch and transmission components to handle the added stress. This article explores various clutch and transmission upgrades that can help ensure your GT-R performs safely and efficiently under increased power levels.

Understanding the Importance of Upgrades

As the GT-R VR38DETT is capable of producing substantial horsepower, the stock clutch and transmission can become overwhelmed when modifications are made. Upgrading these components is crucial for several reasons:

  • Power Handling: Increased horsepower demands stronger components to prevent slippage and ensure power is effectively transferred to the wheels.
  • Performance Reliability: Upgraded parts can enhance the reliability of the drivetrain, reducing the risk of failure during high-performance driving.
  • Driving Experience: High-quality upgrades can improve the overall driving experience, providing smoother engagement and better feedback.

Clutch Upgrades

Choosing the right clutch for your GT-R is pivotal. Here are some popular options that cater to various power levels and driving styles:

  • Single Disc Clutch: Ideal for moderate power upgrades, a high-performance single disc clutch offers improved engagement and can handle increased torque without compromising daily drivability.
  • Multi-Plate Clutch: For those pushing significant power levels, a multi-plate clutch provides superior grip and heat dissipation, making it suitable for track use and high-performance applications.
  • Organic vs. Metallic Discs: Organic discs offer a smoother engagement, while metallic discs are designed for higher performance and durability at the cost of increased pedal effort.

Several brands are recognized for their quality and performance in the GT-R community:

  • Exedy: Known for their high-performance clutches, Exedy offers options that cater to both street and race applications.
  • OS Giken: A popular choice among serious enthusiasts, OS Giken provides multi-plate clutches that excel in high-power scenarios.
  • ACT (Advanced Clutch Technology): ACT clutches are designed to handle increased torque and provide a reliable performance under stress.

Transmission Upgrades

In addition to the clutch, upgrading the transmission is equally important when increasing power. Here are some transmission upgrades to consider:

  • Transmission Cooler: Installing a transmission cooler helps maintain optimal operating temperatures, especially during spirited driving or track days.
  • Upgraded Gear Sets: Stronger gear sets can handle higher torque loads and reduce the risk of failure during aggressive shifts.
  • Short Shifter: A short shifter can enhance the driving experience by providing quicker and more precise gear changes.

Several manufacturers provide reliable transmission upgrades for the GT-R VR38DETT:

  • OS Giken: In addition to clutches, OS Giken offers transmission upgrades that are well-regarded in the performance community.
  • ShepTrans: Known for their custom-built transmissions, ShepTrans specializes in high-performance setups for serious racers.
  • RPS (Racing Performance Systems): RPS provides upgraded gear sets and transmission components designed to withstand high power outputs.

Installation Considerations

When upgrading the clutch and transmission, proper installation is key to ensuring performance and reliability. Here are some important considerations:

  • Professional Installation: It is recommended to have upgrades installed by a professional mechanic familiar with the GT-R platform to avoid potential issues.
  • Break-In Period: Many aftermarket clutches require a break-in period. Follow the manufacturer’s recommendations to ensure longevity.
  • Regular Maintenance: After upgrades, regular maintenance checks are essential to monitor the condition of the clutch and transmission components.

Conclusion

Upgrading the clutch and transmission in your GT-R VR38DETT is a crucial step in handling increased power safely. By selecting the right components and ensuring proper installation, you can enhance the performance and reliability of your vehicle. Whether you’re a casual driver or a dedicated racer, these upgrades will provide the peace of mind needed to enjoy your GT-R to the fullest.
