The Nissan 370Z, equipped with the VQ37VHR engine, is a popular choice among car enthusiasts looking to enhance performance while maintaining reliability. Achieving over 400 horsepower is a common goal for many owners, and with the right modifications, it is entirely possible. In this article, we will explore reliable builds that focus on longevity, specifically highlighting the benefits of the ARK Grip Exhaust and K&N Filters.
Understanding the VQ37VHR Engine
The VQ37VHR is a 3.7-liter V6 engine known for its robust design and impressive performance characteristics. It features an aluminum block and DOHC configuration, allowing for high-revving capabilities and efficient power delivery. However, to push this engine beyond the 400 horsepower mark, careful consideration of modifications is essential.
Key Modifications for Reliable Power
When aiming for high horsepower while ensuring the reliability of the VQ37VHR, several modifications stand out. Below are the essential upgrades for achieving this balance:
- High-Performance Exhaust System
- Cold Air Intake
- Tune and ECU Remapping
- Upgraded Fuel System
- Enhanced Cooling Solutions
High-Performance Exhaust System
One of the most significant upgrades for increasing horsepower is the installation of a high-performance exhaust system. The ARK Grip Exhaust is a popular choice among 370Z owners. It is designed to improve exhaust flow, reduce back pressure, and enhance the overall sound of the vehicle.
Benefits of the ARK Grip Exhaust include:
- Increased horsepower and torque
- Weight reduction compared to stock exhaust
- Aggressive sound profile
- Durable construction for longevity
Cold Air Intake
To maximize the performance gains from the exhaust system, pairing it with a cold air intake is crucial. A cold air intake allows the engine to breathe more freely, drawing in cooler air that is denser and contains more oxygen. This combination can lead to significant power increases.
Tuning for Performance
After installing the exhaust and intake, a proper tune is necessary to unlock the full potential of the modifications. An ECU remap adjusts the engine’s fuel and timing parameters, optimizing performance and ensuring reliability. It is advisable to work with a reputable tuner who specializes in Nissan vehicles for the best results.
Enhancing the Fuel System
To support increased horsepower, upgrading the fuel system is essential. This includes installing high-flow fuel injectors and a performance fuel pump. These components ensure that the engine receives adequate fuel supply, preventing lean conditions that could lead to engine damage.
Cooling Solutions
With increased power comes increased heat. Implementing enhanced cooling solutions, such as an upgraded radiator and oil cooler, can help maintain optimal operating temperatures. This is vital for the longevity of the engine, especially during spirited driving or track days.
Benefits of K&N Filters
In addition to the exhaust and intake upgrades, using K&N Filters can further enhance performance. K&N filters are designed to provide superior airflow while offering excellent filtration. They are washable and reusable, making them a cost-effective option for maintaining engine performance.
- Improved airflow for better engine performance
- Long-lasting and reusable design
- Easy to install and maintain
- Proven filtration efficiency
Conclusion
Building a reliable 370Z VQ37VHR that maintains longevity at 400+ horsepower is achievable with the right modifications. By focusing on key upgrades such as the ARK Grip Exhaust and K&N Filters, along with proper tuning and cooling solutions, enthusiasts can enjoy a powerful yet dependable driving experience. Always remember to prioritize quality parts and professional installation to ensure the best results.
