What Is an LSA Supercharged Engine?

The LSA engine is a 6.2-liter Gen IV small-block V8 developed by General Motors. It is part of the LS engine family but stands apart due to its factory supercharger system, which was engineered from the start for forced induction.

Key technical highlights include:

• Displacement: 6.2 liters (376 cubic inches)
• Configuration: Aluminum block and heads, pushrod V8
• Induction: Factory-installed Eaton 1.9L supercharger
• Compression Ratio: Approximately 9.1:1, optimized for boost
• Cooling: Integrated intercooler system for intake air temperature control

The LSA was originally installed in high-performance factory vehicles such as the Cadillac CTS-V and Chevrolet Camaro ZL1, where it earned a reputation for strong power delivery and durability.

Why the LSA Engine Is So Popular

Factory Supercharged Performance

Unlike many LS engines that require aftermarket forced-induction upgrades, the LSA was designed by GM to be supercharged from the factory, resulting in excellent drivability and reliability under boost.

Excellent Platform for Upgrades

The LSA responds well to modifications such as:

• Smaller supercharger pulleys
• Camshaft upgrades
• Improved cooling systems
• Fuel system enhancements

With proper supporting mods and tuning, the LSA is capable of producing significantly more power than its factory output.

Strong Internal Design

The engine includes reinforced components intended to handle boost, making it a popular choice for high-horsepower street builds and track-focused applications.

Ideal for LS Engine Swaps

Thanks to the LS platform’s compact dimensions and widespread aftermarket support, the LSA is commonly used in:

• Classic muscle cars
• Restomods
• Hot rods
• Performance trucks
• Custom builds

Types of LSA Engines Commonly Available for Sale

When searching for an LSA supercharged engine for sale, you will typically encounter several configurations:

LSA Crate Engines

These are factory-style or remanufactured engines sold as complete assemblies. They are ideal for builders who want a clean starting point with minimal unknowns.

Turn-Key LSA Packages

Turn-key setups often include accessories, wiring, and engine management components, making installation easier for swap projects.

Used or Take-Out LSA Engines

These engines are typically removed from donor vehicles. They can be a cost-effective option but should be carefully inspected for mileage, condition, and completeness.

Built or Modified LSA Engines

Some LSAs are already upgraded with performance internals, making them suitable for high-boost or racing applications.
