The Nissan R32 GT-R is a legendary vehicle known for its performance and engineering excellence. However, when it comes to building a drivetrain capable of handling 700+ horsepower, there are several critical components that need to be addressed to ensure reliability and performance.
Understanding the R32 GT-R Drivetrain
The drivetrain of the R32 GT-R consists of several key components, including the engine, transmission, driveshaft, and differential. Each of these parts plays a vital role in transmitting power from the engine to the wheels. To support a significant increase in horsepower, modifications and upgrades are essential.
Key Components for Upgrading
- Engine
- Transmission
- Driveshaft
- Differential
- Clutch
Engine Modifications
To achieve 700+ horsepower, the RB26DETT engine must undergo significant modifications. Key upgrades include:
- Turbochargers: Upgrading to larger turbochargers can significantly increase power output.
- Fuel System: A high-flow fuel pump and injectors are necessary to support increased fuel demands.
- ECU Tuning: Proper tuning of the engine management system is crucial for maximizing performance.
Transmission Upgrades
The stock transmission may not handle the increased power effectively. Consider the following upgrades:
- Aftermarket Clutch: A performance clutch can provide better grip and durability.
- Short Shifter: A short shifter can improve shifting speed and precision.
- Transmission Cooler: Adding a cooler can help maintain optimal operating temperatures during high-performance driving.
Driveshaft and Differential Considerations
To handle the increased torque and power, both the driveshaft and differential must be upgraded:
- Driveshaft: A lightweight, high-strength driveshaft can reduce rotational mass and improve response.
- Differential: Upgrading to a stronger limited-slip differential (LSD) can enhance traction and stability.
Supporting Modifications
In addition to the primary drivetrain components, several supporting modifications can enhance overall performance:
- Suspension Upgrades: A performance suspension system can improve handling and stability under high power.
- Brake System: Upgrading the brakes is essential for safely managing increased speed and stopping power.
- Tires: High-performance tires can provide the necessary grip for optimal acceleration and cornering.
Conclusion
Building a drivetrain for the R32 GT-R capable of supporting 700+ horsepower requires careful consideration of each component. By upgrading the engine, transmission, driveshaft, and differential, along with supporting modifications, enthusiasts can create a reliable and high-performing vehicle that lives up to the GT-R legacy.
