The Nissan 240SX, known for its lightweight and balanced chassis, has become a popular choice for LS engine swaps. Achieving 550 horsepower from this combination requires careful selection of the camshaft and ECU tuning. In this article, we will explore the best camshaft options and tuning strategies to help you reach your horsepower goals.

Understanding the LS Engine Swap

The LS engine family, known for its durability and performance, is a favorite among car enthusiasts. Swapping an LS engine into a 240SX provides a significant power increase and a more robust powertrain. However, to maximize performance, it is essential to choose the right components and tuning methods.

Choosing the Right Camshaft

When selecting a camshaft for your LS swap, consider the following factors:

  • Lift and Duration: Higher lift and longer duration can increase airflow, leading to more power.
  • LSA (Lobe Separation Angle): A narrower LSA can enhance throttle response and power at lower RPMs.
  • Driveability: Consider how the camshaft will affect idle quality and daily driving.

Here are some top camshaft choices that can help you reach your 550 HP goal:

  • Texas Speed TSP Stage 2 Cam: Offers a great balance of power and driveability.
  • Brian Tooley Racing (BTR) Stage 3 Cam: Designed for high horsepower applications with excellent performance.
  • Comp Cams XFI Cam: Ideal for those looking to maximize power while maintaining daily drivability.

Proper ECU tuning is crucial for optimizing performance and ensuring the engine runs smoothly. A well-tuned ECU can help you achieve the desired horsepower while maintaining reliability.

Types of ECU Tuning

There are several methods for tuning your LS engine, including:

  • Standalone ECU: Provides complete control over engine parameters and is highly customizable.
  • Reflash of Stock ECU: Involves modifying the existing ECU software to improve performance.
  • Piggyback Systems: Adds additional tuning capabilities without replacing the stock ECU.

Here are some effective tuning solutions for your LS swap:

  • HP Tuners: A popular choice for tuning, offering a user-friendly interface and extensive support.
  • EFI Live: Known for its advanced tuning capabilities and flexibility.
  • Holley Terminator X: A standalone ECU option that simplifies the tuning process for LS swaps.

Final Considerations

Reaching 550 HP in your LS swapped 240SX is an achievable goal with the right camshaft and tuning strategy. Always ensure that your engine components are compatible and that you account for supporting modifications such as fuel systems, exhaust, and cooling upgrades.

With careful planning and execution, your 240SX can become a powerful and reliable machine that stands out on the road or track.
