Ls Swap 240sx vs Stock Ka24de: Power Gains and Handling Improvements on the Street and Track

by

The Nissan 240SX has long been a favorite among car enthusiasts, especially for those looking to modify and improve performance. One of the most popular modifications is the LS swap, which involves replacing the stock KA24DE engine with a more powerful LS engine. In this article, we will explore the differences between the LS swap and the stock KA24DE engine, focusing on power gains and handling improvements on both the street and the track.

Understanding the Engines

The first step in comparing the LS swap to the KA24DE is understanding the specifications and characteristics of both engines.

  • KA24DE: A 2.4-liter inline-four engine known for its reliability and decent power output.
  • LS Engine: A series of V8 engines, typically ranging from 5.3 to 6.2 liters, known for their high power potential and aftermarket support.

Power Gains with LS Swap

One of the main reasons for performing an LS swap is the significant power gains that can be achieved. Here are some key points to consider:

  • The stock KA24DE produces around 155 horsepower and 160 lb-ft of torque.
  • In contrast, a stock LS engine can produce anywhere from 300 to 400 horsepower, depending on the variant.
  • Aftermarket modifications for the LS engine can easily push power levels above 500 horsepower.

Torque Characteristics

The torque delivery of the LS engine also provides a significant advantage:

  • LS engines typically generate more low-end torque, enhancing acceleration and responsiveness.
  • This results in a more enjoyable driving experience, especially in street applications.

Handling Improvements

Upgrading to an LS engine not only enhances power but can also improve handling characteristics. Here’s how:

  • The weight distribution changes with an LS swap, often leading to a more balanced chassis.
  • LS engines can be lighter than the KA24DE when considering the entire setup, including accessories.
  • Better weight distribution can lead to improved cornering and stability.

Suspension Upgrades

When performing an LS swap, many enthusiasts take the opportunity to upgrade their suspension as well:

  • Stiffer springs and dampers can help manage the increased power and weight.
  • Upgraded sway bars can reduce body roll and improve cornering performance.

Street Performance vs. Track Performance

While both street and track performance are important, there are differences in how the LS swap impacts each:

  • Street Performance: The increased power and torque of the LS engine provide a thrilling driving experience, making daily driving more enjoyable.
  • Track Performance: On the track, the LS engine’s power allows for faster lap times, while improved handling characteristics enhance cornering capabilities.

Cost Considerations

While the LS swap offers numerous advantages, it’s essential to consider the costs involved:

  • Cost of the LS engine and transmission.
  • Additional components such as wiring harnesses and custom mounts.
  • Labor costs if not performing the swap yourself.

Conclusion

In conclusion, the LS swap offers significant power gains and handling improvements over the stock KA24DE engine. Whether you are looking for a more thrilling street experience or enhanced track performance, the LS engine provides a compelling option for 240SX enthusiasts. However, potential costs and the complexity of the swap should be carefully considered before undertaking this project.
