The VQ35 engine is known for its reliability and performance potential, making it a popular choice among automotive enthusiasts. Building a naturally aspirated (N/A) version of the VQ35 to reach 350 horsepower requires careful selection of components, particularly camshafts and intake systems. In this article, we will explore the best options available for achieving optimal performance from your VQ35 engine.
Understanding the VQ35 Engine
The VQ35 is a 3.5-liter V6 engine that has been utilized in various Nissan and Infiniti models. It features a DOHC design and has a reputation for being a strong foundation for performance builds. To achieve 350 hp from a naturally aspirated setup, modifications must be made to improve airflow and engine efficiency.
Choosing the Right Camshaft
The camshaft plays a critical role in determining the engine’s power characteristics. For a naturally aspirated VQ35 aiming for 350 hp, selecting the right camshaft is essential. Here are some of the best options:
- JWT S3 Cams: These camshafts offer a great balance of performance and drivability, providing a noticeable increase in power without sacrificing low-end torque.
- BC Stage 2 Cams: Known for their aggressive profile, these cams are designed for high RPM performance, making them a solid choice for those looking to maximize horsepower.
- GReddy Cams: These camshafts are engineered for high performance and can significantly improve the engine’s breathing capabilities, leading to better overall power.
Intake System Options
The intake system is crucial for maximizing airflow into the engine. A well-designed intake can lead to significant gains in horsepower. Here are some recommended intake systems for the VQ35:
- Injen SP Series Intake: This intake system is known for its high-quality construction and excellent airflow, making it a popular choice among VQ35 enthusiasts.
- Stillen Cold Air Intake: This system offers improved throttle response and increased horsepower, providing a great option for those looking to enhance their VQ35’s performance.
- AEM Short Ram Intake: Designed for maximum airflow, this intake system is perfect for those seeking a lightweight and efficient solution for their naturally aspirated build.
Combining Camshaft and Intake Choices
To achieve the best results from your VQ35 engine, it is important to combine the right camshaft and intake system. Here are some combinations that work well together:
- JWT S3 Cams with Injen SP Series Intake: This combination provides a strong mid-range power band, ideal for street driving.
- BC Stage 2 Cams with Stillen Cold Air Intake: This pairing is perfect for those looking for high RPM performance and maximum horsepower.
- GReddy Cams with AEM Short Ram Intake: This setup enhances throttle response and overall engine efficiency, making it suitable for track applications.
Tuning and Final Adjustments
After installing the camshaft and intake system, proper tuning is essential to ensure the engine runs smoothly and efficiently. A professional tune can help optimize fuel maps and ignition timing, allowing the engine to reach its full potential. Consider using a standalone ECU or an aftermarket tuning solution for the best results.
Conclusion
Building a 350 hp naturally aspirated VQ35 engine is an achievable goal with the right components. By carefully selecting camshafts and intake systems, and ensuring proper tuning, you can unlock the full potential of this robust engine. Whether you are building for street use or track performance, the VQ35 can deliver impressive results with the right approach.
