The Nissan GT-R, particularly the VR38DETT engine, has become an icon in the automotive world, known for its impressive performance and tuning potential. For enthusiasts looking to build a 600+ horsepower GT-R that is suitable for both daily driving and track use, there are several key upgrades to consider. This guide will outline the recommended modifications that will help achieve this power level while maintaining reliability and drivability.
Understanding the VR38DETT Engine
The VR38DETT is a 3.8-liter twin-turbo V6 engine that powers the Nissan GT-R. Known for its robust construction and advanced technology, it offers a solid foundation for tuning. Before diving into upgrades, it’s essential to understand its components and how they can be enhanced.
Essential Upgrades for 600+ HP
1. Upgraded Turbochargers
To achieve 600+ horsepower, upgrading the turbochargers is a crucial step. Consider the following options:
- Garrett GTX2867R
- HKS GT II Turbo
- AMS Performance Turbo Kits
2. Performance Exhaust System
A high-flow exhaust system will help reduce back pressure and improve exhaust flow. Look for options that include:
- Full cat-back systems
- High-flow downpipes
- Upgraded catalytic converters
3. Enhanced Fuel System
To support increased power levels, upgrading the fuel system is necessary. Key components include:
- Higher flow fuel injectors (e.g., 1050cc or larger)
- Upgraded fuel pumps
- Fuel pressure regulator
4. ECU Tuning
After installing new components, proper ECU tuning is essential to optimize performance and ensure reliability. Consider using:
- ECUtek tuning software
- UpRev tuning solutions
- Custom dyno tuning services
5. Upgraded Intercooler
To maintain optimal intake temperatures, an upgraded intercooler is crucial. Look for options that provide:
- Increased core size
- Improved airflow design
- Enhanced durability
6. Strengthened Engine Internals
For those pushing beyond 600 horsepower, consider upgrading engine internals to ensure reliability. Recommended upgrades include:
- Forged pistons
- Forged connecting rods
- Performance crankshaft
Suspension and Handling Upgrades
With increased power, handling becomes crucial. Upgrading the suspension will improve track performance and daily drivability. Key upgrades include:
- Adjustable coilovers
- Upgraded sway bars
- Performance bushings
Braking System Enhancements
Stopping power is just as important as acceleration. Upgrading the braking system ensures safety and performance on the track. Consider:
- Big brake kits (BBK)
- Performance brake pads
- Stainless steel brake lines
Conclusion
Building a 600+ horsepower GT-R VR38DETT for both daily driving and track use requires careful planning and the right upgrades. By focusing on key components such as turbochargers, fuel systems, and suspension, you can create a balanced and powerful vehicle that performs well in various conditions. Always remember to prioritize safety and reliability in your modifications.
