The VQ37 engine, known for its robust performance and reliability, has become a popular choice among drifting enthusiasts. With the right modifications, it can easily produce over 450 horsepower, making it an ideal setup for track days. In this article, we will explore how to build a reliable 450+ hp setup for drifting using the VQ37 engine.
Understanding the VQ37 Engine
The VQ37 is a naturally aspirated V6 engine that is part of Nissan’s VQ family. It is known for its smooth power delivery and high-revving capabilities. Here are some key features of the VQ37 engine:
- 3.7-liter displacement
- Variable Valve Event and Lift (VVEL) technology
- Aluminum alloy block and DOHC design
- High compression ratio for improved efficiency
Key Modifications for 450+ HP
To achieve a reliable 450+ hp setup, several modifications are necessary. Below are the essential components to consider when building your VQ37 for drifting:
- Forced Induction: Adding a turbocharger or supercharger is crucial for increasing horsepower. A quality kit will provide the necessary boost while maintaining reliability.
- Fuel System Upgrades: Upgrading the fuel pump and injectors ensures that the engine receives adequate fuel to support the increased horsepower.
- Exhaust System: A high-flow exhaust system reduces back pressure and improves engine breathing, which is essential for high-performance applications.
- ECU Tuning: Custom tuning of the engine’s ECU is necessary to optimize performance and ensure that all components work harmoniously.
- Cooling System Enhancements: Upgrading the radiator and adding an oil cooler can help maintain optimal temperatures during extended track sessions.
Forced Induction Options
When it comes to forced induction, you have two primary options: turbocharging and supercharging. Each has its benefits:
- Turbocharging: Typically offers more power potential and efficiency due to the use of exhaust gases to spool the turbo.
- Supercharging: Provides immediate power delivery and is easier to install, but may not achieve the same peak power as a turbo setup.
Enhancing Drivetrain Components
To handle the increased power, it is vital to upgrade various drivetrain components. Here are some recommendations:
- Clutch: A high-performance clutch will provide the necessary grip to handle the added power without slipping.
- Transmission: Consider upgrading to a stronger transmission or reinforcing the stock unit to handle the increased torque.
- Differential: A limited-slip differential (LSD) is essential for improved traction during drifting.
- Driveshaft: Upgrading to a lightweight driveshaft can reduce rotational mass and improve responsiveness.
Suspension and Handling Upgrades
Drifting requires precise handling, which is why suspension upgrades are crucial. Here are some key components to consider:
- Coilovers: Adjustable coilovers allow for fine-tuning of ride height and damping settings, providing better control during drifts.
- Anti-Roll Bars: Upgrading anti-roll bars can reduce body roll and improve cornering stability.
- Camber Kits: Adjustable camber kits enable you to optimize tire contact during drifting, enhancing grip.
- Steering Angle Kits: Increasing steering angle improves maneuverability during drifts, allowing for wider angles and control.
Tuning and Maintenance
Once your VQ37 is built and modified, proper tuning and maintenance are essential for reliability and performance. Here are some tips:
- Regular Dyno Tuning: Periodic dyno tuning ensures that your engine is running efficiently and making the most power.
- Oil Changes: Frequent oil changes with high-quality synthetic oil will keep your engine lubricated and protected.
- Inspect Components: Regularly check all modified components for wear and tear, especially under high-stress conditions.
- Data Logging: Utilize data logging tools to monitor engine performance and identify any potential issues early.
Conclusion
Building a reliable 450+ hp setup for drifting using the VQ37 engine requires careful planning and execution. By focusing on forced induction, drivetrain enhancements, suspension upgrades, and proper tuning, you can create a powerful and dependable drift car. Remember to prioritize maintenance and regular inspections to ensure your setup remains track-ready for every event.
