by

The VQ37 engine is a popular choice among car enthusiasts looking to enhance performance. With the right modifications, it can deliver impressive power and torque. This article provides essential tips on selecting the best camshafts, headers, and forced induction components for your VQ37 performance build.

Understanding the VQ37 Engine

The VQ37 is a 3.7-liter V6 engine produced by Nissan. It is known for its smooth operation and robust performance. Understanding its design and capabilities is crucial when planning modifications.

  • High-revving nature
  • Aluminum block and DOHC design
  • Application in multiple Nissan and Infiniti models

Selecting Camshafts

Choosing the right camshafts can significantly influence the performance of your VQ37 engine. Here are some factors to consider:

  • Duration: Longer duration increases power at higher RPMs but may sacrifice low-end torque.
  • Lift: Higher lift can improve airflow but requires compatible valve springs.
  • Overlap: More overlap can enhance performance at high RPMs but may affect idle quality.

Several aftermarket camshaft options are available for the VQ37, each designed for specific performance goals:

  • JWT (Jim Wolf Technology) Cams: Known for their reliability and performance increase.
  • BC (Brian Crower) Cams: Offer a range of profiles for different builds.
  • Greddy Cams: Focus on high-end power and aggressive performance.

Choosing Headers

Headers play a crucial role in improving exhaust flow and overall engine performance. When selecting headers for your VQ37, consider the following:

  • Material: Stainless steel headers provide durability and resistance to corrosion.
  • Design: Long-tube headers typically offer better performance than short-tube options.
  • Fitment: Ensure headers fit well with other components, including the exhaust system.

Several brands are recognized for their high-quality headers suitable for the VQ37:

  • Motordyne: Known for their innovative designs and performance gains.
  • Stillen: Offers a range of headers designed for street and track use.
  • Invidia: Provides high-performance exhaust solutions with a focus on quality.

Forced Induction Components

Forced induction is one of the most effective ways to increase the power output of your VQ37. Below are key components to consider:

  • Superchargers: Provide immediate power and torque across the RPM range.
  • Turbochargers: Offer significant power gains at higher RPMs but may introduce lag.
  • Intercoolers: Essential for reducing intake temperatures and improving performance.

Several forced induction kits are available for the VQ37, each catering to different performance needs:

  • Stillen Supercharger Kit: Offers a complete package with excellent performance and reliability.
  • Greddy Turbo Kit: Known for its high power output and comprehensive engineering.
  • AMS Performance Turbo Kit: Focuses on maximizing power while maintaining drivability.

Final Considerations

When building a performance VQ37 engine, it’s essential to consider the synergy between all components. Proper tuning is also critical to ensure optimal performance and reliability. Here are some final tips:

  • Consult with Experts: Seek advice from professionals who specialize in VQ37 builds.
  • Budget Wisely: Quality components often come at a premium, but they can save money in the long run.
  • Test and Tune: After installation, conduct thorough testing and tuning to achieve the best results.

By carefully selecting the right camshafts, headers, and forced induction components, you can unlock the full potential of your VQ37 engine. Happy building!
