Ls Swap 240sx: Building a 600+ Hp Drift Machine with Sbc and Holley Fuel System

by

The Nissan 240SX has long been a favorite among drift enthusiasts, known for its lightweight chassis and rear-wheel-drive layout. However, many builders seek to enhance its performance by swapping in a more powerful engine. One of the most popular choices is the LS engine, renowned for its reliability and tuning potential. In this article, we will explore the process of LS swapping a 240SX to create a 600+ horsepower drift machine using a small-block Chevy (SBC) and a Holley fuel system.

Why Choose an LS Engine?

The LS engine series offers several advantages that make it ideal for a drift build:

  • Power and Torque: LS engines can easily produce over 600 horsepower with relatively simple modifications.
  • Weight: LS engines are lighter than many traditional V8s, helping to maintain a favorable weight distribution.
  • Aftermarket Support: The LS platform has extensive aftermarket support, making it easier to find parts and upgrades.

Planning Your Build

Before diving into the swap, it’s essential to plan your build carefully. Consider the following:

  • Budget: Determine how much you are willing to spend on the entire project.
  • Goals: Define your performance goals, such as horsepower targets and intended use.
  • Parts List: Create a detailed list of all necessary components for the swap.

Essential Components for the LS Swap

To successfully complete an LS swap in a 240SX, you will need several key components:

  • LS Engine: Choose an LS engine that fits your power goals, such as the LS3 or L92.
  • Transmission: Select a compatible transmission, like the T56 or 4L80E.
  • Engine Mounts: Use LS swap engine mounts specifically designed for the 240SX.
  • Wiring Harness: A custom wiring harness or an aftermarket option will be necessary.
  • Fuel System: A Holley fuel system is recommended for optimal performance.

Installing the LS Engine

Once you have gathered all the necessary components, it’s time to install the LS engine into your 240SX. Follow these steps:

  • Remove the Old Engine: Start by removing the stock KA24DE engine and transmission.
  • Install Engine Mounts: Secure the LS engine mounts to the chassis.
  • Position the LS Engine: Carefully lower the LS engine into place, ensuring proper alignment with the mounts.
  • Connect Transmission: Attach the chosen transmission to the LS engine.
  • Secure Everything: Ensure all mounts and bolts are tightened to specifications.

Setting Up the Fuel System

A reliable fuel system is crucial for achieving high horsepower. Here’s how to set up a Holley fuel system:

  • Fuel Tank: Consider upgrading to a fuel tank that accommodates higher flow rates.
  • Fuel Pump: Install a Holley fuel pump capable of supporting your horsepower goals.
  • Fuel Lines: Use high-quality fuel lines to prevent leaks and ensure proper flow.
  • Fuel Injectors: Choose injectors that match your engine’s performance requirements.

Tuning for Performance

After the installation is complete, tuning is essential to maximize performance. Consider these steps:

  • ECU Tuning: Use a standalone ECU or reprogram the stock ECU for optimal performance.
  • Dyno Testing: Take your car to a professional dyno for precise tuning and adjustments.
  • Monitor Performance: Keep track of air-fuel ratios and other parameters during testing.

Final Touches and Drift Setup

With the engine and fuel system set up, it’s time to focus on the final touches and drift setup:

  • Suspension Upgrades: Install coilovers and adjustable arms for better handling.
  • Wheels and Tires: Choose lightweight wheels and high-performance tires for drifting.
  • Braking System: Upgrade to a more robust braking system for better control.
  • Safety Gear: Ensure you have proper safety gear, including a roll cage and harnesses.

Conclusion

Building a 600+ horsepower LS-swapped 240SX is an exciting project that can yield incredible results on the track. By carefully planning your build, selecting quality components, and tuning for performance, you can create a drift machine that not only looks great but also performs exceptionally well. Embrace the journey and enjoy the thrill of drifting with your newly built 240SX!
