by

The VQ37 engine, known for its robust performance and tuning potential, is a popular choice for those looking to build high horsepower vehicles. Achieving a target of 550 horsepower requires careful consideration of various components, particularly the camshaft and forced induction options. In this article, we will explore the top camshaft choices and the best forced induction methods to help you reach that goal.

Understanding the VQ37 Engine

The VQ37 is a part of Nissan’s VQ engine family, featuring a 3.7-liter V6 configuration. It is renowned for its smooth power delivery and high-revving nature. To maximize its potential, tuning enthusiasts often explore various modifications, particularly in the areas of camshaft upgrades and forced induction systems.

Top Camshaft Choices for VQ37

Choosing the right camshaft is crucial for achieving optimal performance. Here are some of the top camshaft options for the VQ37 engine:

  • JWT C2 Cams: Known for their aggressive profile, JWT C2 cams increase both horsepower and torque across the RPM range.
  • BC 272 Cams: These cams provide a good balance between street drivability and performance, ideal for a daily driver.
  • Greddy Cams: Designed for high RPM performance, Greddy cams are perfect for those looking to push their VQ37 to the limits.
  • HKS Cams: HKS offers a variety of cam profiles that cater to different tuning needs, from mild to wild setups.

Factors to Consider When Choosing a Camshaft

When selecting a camshaft for your VQ37 build, consider the following factors:

  • Intended Use: Determine if the vehicle will be used primarily for street driving, track racing, or a combination of both.
  • RPM Range: Different camshafts perform better at specific RPM ranges, so choose one that aligns with your power goals.
  • Compatibility: Ensure the camshaft is compatible with other engine modifications, such as forced induction systems.
  • Installation Complexity: Some camshafts may require additional modifications or professional installation.

Forced Induction Options for VQ37

Forced induction is essential for reaching high horsepower goals. Here are some popular forced induction options for the VQ37 engine:

  • Turbocharging: A turbocharger can significantly increase horsepower by forcing more air into the engine.
  • Supercharging: A supercharger provides instant power and is often easier to install than a turbo system.
  • Twin-Turbo Kits: These kits offer the benefits of both turbocharging and improved throttle response.
  • Custom Kits: For those looking for a unique setup, custom forced induction kits can be designed to meet specific performance goals.

Here are some popular turbocharging kits that can help you achieve 550 HP with the VQ37:

  • AMS Performance Turbo Kit: Known for its high-quality components and impressive power gains.
  • Invidia Turbo Kit: Offers a balance of performance and reliability, making it a great choice for street applications.
  • GTM Turbo Kit: A comprehensive kit that includes everything needed for a successful installation and tuning.
  • Stillen Twin Turbo Kit: Provides a significant boost in horsepower while maintaining drivability.

Supercharging Options

If you prefer supercharging, here are some options that pair well with the VQ37:

  • Stillen Supercharger Kit: A popular choice that offers reliable performance and ease of installation.
  • Vortech Supercharger: Known for its efficiency and power delivery, ideal for street and track use.
  • Jackson Racing Supercharger: Provides a good balance of performance with a focus on low-end torque.

Supporting Modifications

To achieve and maintain 550 horsepower, consider additional modifications that support your engine’s performance:

  • Upgraded Fuel System: Ensure your fuel pump and injectors can handle the increased fuel demands.
  • High-Performance Exhaust: A free-flowing exhaust system can help improve power and efficiency.
  • ECU Tuning: Proper tuning is essential to maximize the performance of your engine and forced induction system.
  • Cooling Upgrades: Consider upgrading your intercooler or radiator to manage increased heat levels.

Importance of Tuning

Tuning is a critical aspect of building a high horsepower engine. A well-tuned engine will not only perform better but will also be more reliable. It is advisable to work with a professional tuner who has experience with VQ engines to ensure optimal results.

Conclusion

Building a 550 horsepower VQ37 engine is an achievable goal with the right camshaft choices and forced induction options. By selecting the appropriate components and ensuring proper tuning, you can unlock the full potential of your VQ37 and enjoy an exhilarating driving experience. Remember to consider supporting modifications to enhance reliability and performance as you embark on this exciting project.
