Description
LSA Supercharged Engine Forsale
LSA Supercharged Engine Forsale is one of General Motors’ most respected high-performance 6.2L supercharged V8 engines, known for its balance of raw horsepower, factory reliability, and tuning potential. Found in legendary vehicles like the Cadillac CTS-V and Chevrolet Camaro ZL1, the LSA remains a top choice for performance builds, engine swaps, and horsepower upgrades.
In this guide, we break down the LSA engine specs, performance, reliability, tuning potential, and common applications.
What is the LSA Supercharged Engine Forsale?
The LSA engine is a 6.2-liter (376 cu in) Gen IV small-block V8 developed by General Motors.
It is part of the LS engine family but stands out due to its factory-installed supercharger system, making it significantly more powerful than naturally aspirated LS engines like the LS3.
The LSA was designed for factory supercharged performance cars, delivering instant torque and strong acceleration without sacrificing drivability.
LSA Supercharged Engine Forsale Specs (Factory Configuration)
Key factory specifications of the LSA engine include:
- Displacement: 6.2L (376 cu in)
- Configuration: 90° V8
- Aspiration: Eaton TVS 1.9L Roots supercharger
- Compression ratio: 9.1:1
- Horsepower: ~556–580 hp (factory tune)
- Torque: ~551–556 lb-ft
- Fuel system: Sequential fuel injection
- Block: Cast aluminum Gen IV LS block
- Redline: ~6,200 RPM
The LSA uses a heavy-duty internals package, including:
- Forged steel crankshaft
- Strengthened pistons
- Oil cooling jets
- Intercooled supercharger system
How the LSA Supercharger Works
The LSA engine uses an Eaton TVS Roots-type supercharger, which forces compressed air into the engine.
Here’s what that means in simple terms:
- The supercharger is driven by the engine belt
- It compresses air before it enters the cylinders
- More air = more fuel burned = more power
- An air-to-liquid intercooler reduces heat for efficiency
This setup provides:
- Instant throttle response
- Strong low-end torque
- Smooth power delivery across RPM range
Vehicles That Use the LSA Engine
The LSA was factory installed in several high-performance GM vehicles:
- Cadillac CTS-V (2009–2015)
- Chevrolet Camaro ZL1 (2012–2015)
- HSV GTS (Holden performance models)
These vehicles became known for:
- 0–60 mph in under 4 seconds
- High top-speed capability
- Track-ready performance with luxury comfort
LSA Engine Performance & Tuning Potential
One of the biggest reasons enthusiasts love the LSA is its huge tuning potential.
With simple upgrades, the LSA can reliably produce:
- Stock: ~556–580 hp
- Bolt-ons + tune: 650–700 hp
- Upgraded blower/pulley: 700–800+ hp
- Built engine setups: 900+ hp (with forged internals)
Popular upgrades include:
- Smaller supercharger pulley
- Cold air intake system
- High-flow exhaust headers
- Upgraded fuel injectors
- Heat exchanger upgrade
LSA Engine Reliability
The LSA is considered a very strong factory performance engine, especially compared to many other supercharged engines.
Strengths:
- Forged crankshaft durability
- Strong aluminum block design
- Factory oil cooling system
- Proven supercharger system
LSA Supercharged Engine Forsale Common weaknesses:
- Heat buildup under high boost
- Supercharger pulley limitations
- Fuel system limitations at high horsepower
With proper tuning and cooling upgrades, the LSA is widely considered reliable up to 700–750 hp.
