The following figures reflect U.S.-market horsepower ratings by trim for the 2004 Civic.
- DX/LX: 115 horsepower, torque around 110 lb-ft. This baseline engine emphasizes efficiency.
- EX: 127 horsepower, torque around 114 lb-ft. The EX adds higher output and improved performance.
- Si: 160 horsepower, torque around 141 lb-ft. The Si uses a larger 2.0-liter engine for sportier performance.
In summary, the power output climbs from about 115 hp in base models to 127 hp in EX, and up to 160 hp in the Si, reflecting a range from everyday efficiency to sport-oriented performance.
Notes on market variants
The 2004 Civic Si was offered as a two-door coupe in the United States with the 2.0-liter K-series engine producing roughly 160 hp. A sedan variant for the Si was not marketed in the U.S. in 2004. Other markets sometimes report different horsepower figures due to different engines and tuning.
