Description

The Acura B18B1 engine is a 1.8-liter, 4-cylinder non-VTEC power plant commonly found in models such as the Acura Integra LS, GS, and SE. With its 1834cc displacement and a 9.2:1 compression ratio, this engine was factory-rated to deliver approximately 140-142 horsepower at 6,300 RPM and 127-128 lb-ft of torque at 5,100-5,200 RPM. This engine is known for its robust construction and a spirited yet fuel-efficient performance, making it a popular choice for daily drivers and custom builds. The B18B1 is part of Honda's B-series engine family, recognized for its reliability and potential for modification. For reference, the engine oil capacity for Integra models equipped with the B18B1 is typically 4.0 quarts. While the B18B1 is a capable engine, modifications such as LS-VTEC conversions or turbocharger installations can significantly increase its power output, with some builds achieving upwards of 190-250 wheel horsepower on pump gas or even higher with more extensive turbo builds.
