Nissan 350z Camshaft Upgrades: Increasing Power from 287 to 320 Hp

by

The Nissan 350Z is a beloved sports car known for its sleek design and impressive performance. One of the key areas where enthusiasts look to enhance their vehicle’s capabilities is through camshaft upgrades. In this article, we will explore how camshaft upgrades can increase the power of the Nissan 350Z from 287 to 320 horsepower.

Understanding Camshafts

Before diving into specific upgrades, it’s important to understand what a camshaft is and its role in engine performance. The camshaft controls the timing and duration of the engine’s intake and exhaust valves, playing a crucial part in the overall efficiency and power output of the engine.

Benefits of Upgrading Camshafts

Upgrading the camshaft can lead to significant improvements in performance. Here are some of the benefits:

  • Increased Horsepower: Higher lift and longer duration can boost horsepower.
  • Improved Torque: Better torque delivery across the RPM range.
  • Enhanced Engine Response: Quicker throttle response and overall engine efficiency.
  • Better Sound: Upgraded camshafts can give your engine a more aggressive sound.

Choosing the Right Camshaft

When selecting a camshaft for your Nissan 350Z, consider the following factors:

  • Lift: The height the valve opens. Higher lift can lead to more airflow.
  • Duration: The amount of time the valve is open. Longer duration can improve top-end power.
  • Overlap: The period when both intake and exhaust valves are open. More overlap can enhance performance but may affect idle quality.
  • Intended Use: Consider whether the car will be used for daily driving, racing, or a mix of both.

Several camshaft options are popular among Nissan 350Z enthusiasts. Here are some notable choices:

  • JWT S3 Cams: Known for good mid-range power and excellent drivability.
  • BC 272 Cams: Offers a significant power increase with a focus on high RPM performance.
  • GReddy Cams: Designed for a balance of power and smooth operation.
  • Spec Cams: Targeted for racing applications, providing maximum performance at high RPMs.

Installation Considerations

Installing a new camshaft requires careful consideration and expertise. Here are some key points to keep in mind:

  • Professional Installation: It’s recommended to have a professional mechanic perform the installation to ensure proper alignment and timing.
  • Supporting Mods: Consider upgrading other components such as the ECU, intake, and exhaust systems to maximize the benefits of the camshaft upgrade.
  • Break-In Period: Allow for a proper break-in period after installation to ensure longevity and performance.

Tuning After Camshaft Upgrade

After installing a new camshaft, tuning is essential to achieve optimal performance. Here’s why tuning matters:

  • Fuel Mapping: Adjusting the fuel map ensures the engine runs efficiently with the new camshaft.
  • Ignition Timing: Proper ignition timing can maximize power output and engine response.
  • Performance Gains: A good tune can significantly enhance the performance gains from the camshaft upgrade.

Conclusion

Upgrading the camshaft on your Nissan 350Z can lead to impressive power gains, increasing horsepower from 287 to 320 HP. By understanding the benefits, choosing the right camshaft, and ensuring proper installation and tuning, you can unlock your vehicle’s full potential and enjoy a thrilling driving experience.
