The Nissan 370Z, equipped with the VQ37VHR engine, is a powerhouse known for its performance and tuning potential. Enthusiasts often seek ways to enhance power output, and two popular upgrades are the JWT S1 camshafts and the Z1 Motorsports intake manifold. This article explores how these modifications can maximize the power of your 370Z.
Understanding the VQ37VHR Engine
The VQ37VHR engine is a 3.7-liter V6 that delivers impressive performance straight from the factory. With a dual overhead cam design and variable valve timing, it provides a solid foundation for tuning. However, to unlock its full potential, modifications like camshaft replacements and upgraded intake manifolds can be crucial.
JWT S1 Camshafts
The JWT S1 camshafts are designed specifically for the VQ37VHR engine to enhance performance across the RPM range. These camshafts provide several benefits that contribute to increased horsepower and torque.
Benefits of JWT S1 Camshafts
- Improved Airflow: The S1 camshafts feature higher lift and longer duration, allowing for better airflow into and out of the engine.
- Increased Power Band: These camshafts broaden the power band, providing a more usable power range for drivers.
- Enhanced Throttle Response: The improved timing and lift characteristics lead to quicker throttle response, making the car feel more responsive.
Z1 Motorsports Intake Manifold
The Z1 Motorsports intake manifold is another critical component in maximizing the performance of the 370Z. Designed to optimize airflow, this manifold complements the JWT S1 camshafts perfectly.
Features of the Z1 Intake Manifold
- Increased Plenum Volume: The Z1 intake manifold features a larger plenum volume, which helps to improve airflow and increase power.
- Optimized Runner Design: The runners are designed to minimize turbulence, allowing for smoother airflow to the engine.
- Compatibility: This manifold is designed to work seamlessly with the JWT S1 camshafts, ensuring that the engine breathes efficiently.
Combining JWT S1 Camshafts and Z1 Intake Manifold
When combined, the JWT S1 camshafts and Z1 Motorsports intake manifold create a synergy that significantly boosts the performance of the VQ37VHR engine. Together, they enhance airflow, improve combustion efficiency, and ultimately lead to higher power output.
Expected Power Gains
Many enthusiasts report substantial power gains after installing both the JWT S1 camshafts and the Z1 intake manifold. On average, users can expect:
- Increase of 20-30 horsepower at the wheels.
- Improved torque figures, particularly in the mid-range.
- Enhanced overall driving experience with a more responsive throttle.
Installation Considerations
Installing the JWT S1 camshafts and the Z1 intake manifold requires a good understanding of engine mechanics. Here are some key considerations:
- Professional Installation: It is highly recommended to have these components installed by a professional to ensure proper fitment and tuning.
- Tuning Required: After installation, an ECU tune is necessary to maximize the benefits of the upgrades.
- Supporting Mods: Consider additional modifications such as upgraded exhaust systems and fuel injectors for optimal performance.
Conclusion
The combination of JWT S1 camshafts and the Z1 Motorsports intake manifold provides a powerful upgrade path for 370Z enthusiasts looking to maximize their car’s performance. With improved airflow, increased power, and enhanced throttle response, these modifications can transform the driving experience. Always ensure professional installation and proper tuning to fully realize the potential of your VQ37VHR engine.
