The Nissan R32 GT-R is renowned for its performance and engineering excellence. However, to maximize its potential, especially under high power conditions, upgrading the transfer case and drivetrain components is essential. This article delves into the various upgrades available for the R32 GT-R’s transfer case and drivetrain, ensuring reliability and performance on the track and the street.
Understanding the R32 GT-R Drivetrain
The R32 GT-R features a sophisticated all-wheel-drive system that distributes power between the front and rear axles. This system, while robust, can experience stress under high power outputs, necessitating upgrades to maintain performance and reliability.
Transfer Case Upgrades
The transfer case in the R32 GT-R is a critical component that manages power distribution. Upgrading this unit can significantly enhance performance and reliability.
Strengthened Transfer Cases
Replacing the stock transfer case with a strengthened unit can help withstand increased torque and power. Options include:
- Aftermarket transfer cases designed for higher torque applications.
- Reinforced housings to prevent cracking under stress.
Transfer Case Gears
Upgrading the gears within the transfer case can improve power handling and response. Consider:
- High-strength gear sets made from advanced materials.
- Lower gear ratios for improved acceleration.
Drivetrain Component Upgrades
In addition to the transfer case, several drivetrain components can be upgraded to enhance performance and reliability.
Driveshaft Upgrades
The driveshaft is crucial for transferring power from the transfer case to the axles. Upgrading to a stronger driveshaft can prevent failures:
- Lightweight aluminum or carbon fiber driveshafts for reduced weight.
- High-strength steel driveshafts for increased durability.
Differential Upgrades
The differential plays a vital role in distributing power to the wheels. Upgrading to a performance differential can enhance traction and handling:
- Limited-slip differentials for improved power distribution.
- Adjustable differentials for tuning performance characteristics.
Axle Upgrades
Upgrading the axles is essential for handling increased power without failure:
- High-strength aftermarket axles designed for performance applications.
- Reinforced axle shafts to withstand higher torque loads.
Performance Tuning for Reliability
Beyond hardware upgrades, tuning the vehicle is crucial to ensure that all components work harmoniously under high power conditions.
ECU Tuning
Optimizing the engine’s ECU can help manage power delivery and prevent drivetrain stress:
- Custom ECU maps that account for upgraded components.
- Boost control adjustments for smoother power delivery.
Suspension Tuning
Proper suspension tuning can enhance traction and handling, which is vital for high-power applications:
- Adjustable coilovers for optimal ride height and stiffness.
- Upgraded sway bars to reduce body roll during aggressive driving.
Conclusion
Upgrading the transfer case and drivetrain components of the R32 GT-R is essential for ensuring reliability under high power. By investing in quality parts and tuning, enthusiasts can maximize performance while maintaining the integrity of their vehicle. These upgrades not only enhance power handling but also improve overall driving experience, making the R32 GT-R a true performance icon.
