Top Supporting Mods for Ls Swap: Camshaft, Intake, and Exhaust Upgrades for Max Power

by

The LS engine swap has become a popular choice among car enthusiasts looking to boost performance and reliability. However, to truly unlock the potential of an LS engine, supporting modifications are essential. This article will explore the top supporting mods, focusing on camshaft, intake, and exhaust upgrades that maximize power output.

Understanding the LS Engine Swap

The LS engine, known for its durability and power potential, is a versatile choice for many builds. However, to achieve optimal performance, it’s crucial to consider supporting modifications that enhance airflow, improve engine timing, and increase exhaust efficiency.

Camshaft Upgrades

A camshaft upgrade is one of the most impactful modifications you can make to an LS engine. The camshaft controls the timing and duration of the engine’s intake and exhaust valves, which directly affects performance.

Choosing the Right Camshaft

When selecting a camshaft, consider the following:

  • Lift: Higher lift allows more air to enter the combustion chamber.
  • Duration: Longer duration increases the time the valves are open, enhancing airflow.
  • LSA (Lobe Separation Angle): Affects idle quality and power band; narrower angles improve low-end torque.

Some popular camshaft options for LS swaps include:

  • Texas Speed Stage 1 Cam
  • Brian Tooley Racing (BTR) Stage 2 Cam
  • Comp Cams XFI RPM Cam

Intake Upgrades

Upgrading the intake system is crucial for maximizing the performance of an LS engine. A high-performance intake manifold can significantly improve airflow and throttle response.

Types of Intake Manifolds

There are several types of intake manifolds to consider:

  • Single Plane Manifolds: Best for high RPM applications, providing maximum airflow.
  • Dual Plane Manifolds: Better for street applications, offering improved low-end torque.
  • LS3 Manifold: A popular choice for its excellent airflow characteristics.

Consider these popular intake upgrades for your LS swap:

  • Holley LS Intake Manifold
  • FAST LSX Intake Manifold
  • Edelbrock Victor Jr. LS Manifold

Exhaust Upgrades

Exhaust upgrades are equally important for releasing the power generated by the LS engine. A free-flowing exhaust system minimizes back pressure and enhances performance.

Choosing Exhaust Components

Key components to consider for exhaust upgrades include:

  • Headers: Long-tube headers provide the best performance by improving exhaust flow.
  • Cat-back Exhaust Systems: A quality cat-back system enhances sound and performance.
  • High-Flow Catalytic Converters: Reducing restrictions while remaining emissions compliant.

Here are some popular exhaust upgrades for LS swaps:

  • Hooker Long Tube Headers
  • Borla Cat-Back Exhaust System
  • MagnaFlow Performance Exhaust System

Conclusion

Upgrading the camshaft, intake, and exhaust systems are essential steps in maximizing the power of your LS swap. Each component plays a vital role in improving airflow, enhancing performance, and ensuring your engine operates efficiently. By choosing the right supporting mods, you can unlock the full potential of your LS engine and enjoy an exhilarating driving experience.
