The Nissan GT-R is renowned for its performance, but to maintain that edge, the transmission must be reinforced. Upgrading the synchros and bearings can significantly enhance durability and reliability.
Understanding the Importance of Transmission Reinforcement
The transmission is one of the most critical components of the GT-R, responsible for transferring power from the engine to the wheels. Over time, high-performance driving can lead to wear and tear on the transmission’s internal parts. This is where reinforcement becomes essential.
Why Upgrade Synchros?
Synchros play a vital role in ensuring smooth gear shifts. Upgrading to high-performance synchros can provide several benefits:
- Improved Shift Quality: Enhanced synchros reduce grinding and improve the overall feel of shifting.
- Increased Longevity: Better materials can withstand higher levels of stress and heat.
- Faster Shifts: Upgraded synchros allow for quicker engagement, improving lap times.
Benefits of Bearing Upgrades
Bearings are crucial for the smooth operation of the transmission. Upgrading bearings can lead to significant improvements:
- Reduced Friction: High-performance bearings decrease friction, leading to better efficiency.
- Enhanced Heat Resistance: Upgraded bearings can withstand higher temperatures, preventing failure.
- Improved Reliability: Better bearings reduce the risk of catastrophic transmission failure.
Choosing the Right Components
When considering upgrades, it’s essential to choose the right components. Not all synchros and bearings are created equal. Look for reputable brands that specialize in high-performance parts.
Recommended Brands for Upgrades
- OS Giken: Known for their high-quality synchros that enhance shifting performance.
- Exedy: Offers a range of bearings designed for high-performance applications.
- ACT: Provides durable components that can withstand the rigors of racing.
Installation Process
Upgrading synchros and bearings is a complex process that requires mechanical expertise. Here’s a general overview of the installation steps:
- Disassemble the Transmission: Remove the transmission from the vehicle and disassemble it carefully.
- Remove Old Components: Take out the old synchros and bearings, noting their placement for reassembly.
- Install New Synchros: Place the upgraded synchros in their respective positions.
- Replace Bearings: Install the new bearings, ensuring they are seated correctly.
- Reassemble the Transmission: Carefully reassemble the transmission, double-checking all components.
- Test the Transmission: Once reinstalled, test the transmission for proper operation.
Conclusion
Upgrading the synchros and bearings in a GT-R transmission is a worthwhile investment for those seeking enhanced durability and performance. By choosing high-quality components and ensuring proper installation, drivers can enjoy a more reliable and enjoyable driving experience.
