The B20B engine is a 2.0-liter inline-four from Honda’s B-series family, best known for its use in the first-generation Honda CR-V and a handful of market-specific models. In practice, the CR-V is the model most people associate with the B20B, with other regional applications appearing in limited numbers.
What the B20B engine is
The B20B is part of Honda’s B-series family, a line of 4-cylinder engines introduced in the 1980s and refined through the 1990s. The “B” designation denotes the family, while “20B” signals a 2.0-liter displacement. These engines are typically dual overhead camshaft (DOHC) designs with multi-valve configuration and are known for smooth power delivery and broad mid-range torque. Variants such as B20B1 were used in different markets, making the exact spec sheet slightly regional.
Honda models that used the B20B
Below is the model most widely documented to have used the B20B engine. Availability varied by region and production year.
- Honda CR-V (first generation, 1997–2001) — in several overseas and regional markets, the CR-V came with a B20B 2.0-liter engine configuration instead of other powerplants used in North America.
In addition to the CR-V, there were limited, region-specific appearances of the B20B in other Honda models during the 1990s. Documentation on these applications is less consistent, and some markets used different B-series variants (such as B20Z or other 2.0L configurations) in similar vehicles. If you’re evaluating a particular VIN or import, verify the engine code on the engine block or valve cover and cross-check with official service manuals for your region.
Regional variations and other possible applications
Honda’s regional practices in the 1990s meant that some markets experimented with B20B variants in sedans, wagons, or light SUVs beyond the CR-V. However, the CR-V remains the flagship model most commonly associated with the B20B, and many enthusiasts identify it as the canonical B20B application. Confirming the exact engine code for a specific vehicle requires checking the stamping on the engine or consulting the vehicle’s service documentation.
Summary
The B20B engine sits within Honda’s B-series lineage and is most closely linked to the first-generation Honda CR-V, particularly in non-North American markets. While other region-specific Hondas may have carried B20B variants, the CR-V is the primary model people reference when discussing the B20B. When in doubt, verify the engine code on the engine itself and consult region-specific manuals or Honda’s official documentation to confirm the exact specification for a given vehicle.
