Supercharged LSA Engine with Eaton Induction
The LSA’s supercharged design provides forced induction without requiring the buyer to select a separate aftermarket supercharger system. The advertised Eaton 1.9L unit and integrated air-to-water intercooling system form part of the engine’s induction setup.
For a successful installation, verify the exact supercharger configuration, intercooler hardware, coolant circuit, belt drive, and required accessories. These details affect installation planning and compatibility with your vehicle’s engine bay.

Before ordering, confirm the ECU calibration, harness connections, sensor requirements, and compatibility with your transmission and intended vehicle. You should also account for fuel delivery, cooling, exhaust routing, engine mounts, and accessory clearance.
