The Nissan GT-R is renowned for its performance and advanced technology, particularly the ATTESA all-wheel-drive system. However, many enthusiasts seek to enhance the vehicle’s power and performance further through transmission upgrades. This article explores the costs and benefits of such upgrades, focusing on achieving over 80 additional horsepower.
Understanding the ATTESA System
The ATTESA (Advanced Total Traction Engineering System for All-Terrain) system is a sophisticated all-wheel-drive technology that optimally distributes power between the front and rear wheels. This system plays a crucial role in the GT-R’s handling and acceleration, making it a prime candidate for upgrades.
Benefits of Transmission Upgrades
Upgrading the transmission in a Nissan GT-R can yield significant performance benefits. Here are some key advantages:
- Increased Power Output: Upgrades can help achieve more than 80 additional horsepower, enhancing overall performance.
- Improved Shifting Speed: Enhanced transmission components can lead to quicker gear changes, improving acceleration.
- Better Torque Management: Upgraded systems can manage torque more effectively, improving traction and stability.
- Customization Options: Upgrades allow for tuning to specific driving styles, whether for racing or everyday driving.
Types of Transmission Upgrades
There are several types of transmission upgrades available for the Nissan GT-R, each with its unique benefits:
- Transmission Rebuilds: A complete overhaul of the existing transmission can improve reliability and performance.
- Aftermarket Transmission Kits: These kits often include high-performance components designed for enhanced power handling.
- Upgraded Torque Converters: A higher stall speed can improve acceleration by allowing the engine to reach optimal power more quickly.
- ECU Tuning: Adjusting the engine control unit can optimize power delivery and improve transmission performance.
Cost Considerations
When considering transmission upgrades for the GT-R, it’s essential to understand the associated costs. The expenses can vary widely based on the type of upgrade and the components chosen:
- Transmission Rebuilds: Costs can range from $3,000 to $7,000, depending on the extent of the work and parts used.
- Aftermarket Kits: These kits can cost between $2,500 and $5,000, with additional installation fees.
- Torque Converters: Upgrading a torque converter typically costs between $800 and $1,500.
- ECU Tuning: Tuning services can range from $500 to $1,500, depending on the complexity of the tune.
Potential Drawbacks
While the benefits of transmission upgrades are significant, there are potential drawbacks to consider:
- Increased Wear and Tear: More power can lead to faster wear on transmission components.
- Cost of Maintenance: Upgraded systems may require more frequent maintenance, leading to higher long-term costs.
- Potential for Overheating: Performance upgrades can increase the risk of overheating if not managed correctly.
- Insurance Implications: Modifications may affect insurance premiums and coverage options.
Conclusion
Upgrading the transmission in a Nissan GT-R can offer substantial benefits, including increased horsepower and improved performance. However, these upgrades come with costs and potential drawbacks that enthusiasts should carefully consider. By weighing the benefits against the costs, GT-R owners can make informed decisions that align with their performance goals.
