Direct 2.2L Swap Compatibility: Not Supported
The 2.2L Ecotec engine (found in later Saturn Ions, Chevy Cavaliers, and Pontiac Sunfires) is not directly compatible with the SL2’s chassis or electronics. Saturn’s S-Series was never factory-equipped with a 2.2L engine, so this swap is non-interchangeable without major modification.
