The 2.0-liter displacement provides a good balance between power and fuel efficiency. The engine is capable of generating approximately 130 horsepower at 6,500 RPM and 127 lb-ft of torque at 4,800 RPM. These numbers make it a great choice for those seeking a lively driving experience without sacrificing everyday practicality.

The Mazda 300-66021B engine is known for its durability and reliability. It features a compact, aluminum engine block and a strong, forged steel crankshaft. This design not only reduces the overall weight of the engine but also helps to dissipate heat effectively.

The engine is equipped with a distributor-less ignition system, which eliminates the need for a traditional distributor and distributor cap. This design not only simplifies the engine's electrical system but also improves reliability and reduces the likelihood of wear and tear.

The Mazda 300-66021B engine also features a multi-point fuel injection system, which ensures precise and efficient fuel delivery to the combustion chamber. This system helps to optimize engine performance and improve fuel economy, making it an excellent choice for those seeking a balance between power and efficiency.

The engine is compatible with various transmission options, including a 5-speed manual transmission or a 4-speed automatic transmission. This versatility allows owners to choose the driving experience that best suits their preferences and driving conditions.

Overall, the Mazda 300-66021B engine is a well-engineered, reliable, and powerful choice for those seeking a great driving experience from their vehicle. Its compact size, impressive power output, and excellent fuel efficiency make it a popular choice among Mazda enthusiasts and daily drivers alike.

The Mazda 300-66021B engine, a 2.0L 8-valve 4-cylinder unit, was produced by Mazda for select models during the late 1990s. Like any engine, it comes with its advantages and disadvantages.
