• Compression Ratio: 8.8:1 (low compression)
• Power Output: Around 130-140 horsepower (depending on the vehicle model)
• Torque Output: Approximately 133 lb-ft of torque
• Applications: Honda CRV, Civic, Integra (varies by year and region)

Key Features of the B20B JDM Engine

1. Low Compression: The B20B’s low compression ratio of 8.8:1 makes it ideal for forced induction (such as turbocharging or supercharging) because it allows for higher boost levels without the risk of engine knock or detonation. This low compression is a significant benefit for those looking to build high-power setups.

2. Durable Engine Block: The B20B is known for its strong engine block, which can withstand higher levels of power and torque compared to some other engines in the B-series family. This durability makes it an excellent choice for enthusiasts who want to build a high-performance engine.

3. DOHC Design: The DOHC design ensures that the engine can breathe more efficiently, allowing for higher RPMs and increased performance. This design is ideal for those looking to increase the engine’s output.

4. JDM Sourcing: As a JDM (Japanese Domestic Market) engine, the B20B has been designed and manufactured to meet the rigorous standards of Japanese automakers, ensuring quality and reliability. JDM engines are often sought after by enthusiasts because of their superior performance and often lower mileage compared to domestically sourced engines.

5. Aftermarket Support: The B20B engine shares a lot of parts with other B-series engines, such as the B18 and B16, making it easier to find aftermarket parts for modifications. From pistons to cams and turbos, there are numerous parts available to upgrade this engine.

Applications of the B20B Engine

• Honda CRV: In the CRV, the B20B engine offers a solid balance of power and efficiency. Its low compression is perfect for adding forced induction, turning the CRV into a fun and capable performance vehicle.

• Honda Civic: When swapped into a Civic, the B20B engine provides a significant power boost over the stock engines typically found in these vehicles. With a low compression engine, it’s an excellent candidate for turbo builds.

• Honda Integra: The B20B engine swap into an Integra is another popular option, as it provides more low-end torque compared to the stock B18 engines. The extra displacement and lower compression ratio allow for a smoother power delivery, which enthusiasts appreciate in the Integra.

Why Choose the B20B Engine?

There are several reasons why the B20B JDM engine is a popular choice for Honda tuners:

1. Great for Forced Induction: Due to its low compression ratio, the B20B is an excellent choice for those looking to add a turbocharger or supercharger to their build. The low compression allows for higher levels of boost without the risk of detonation, giving tuners the ability to make significant power gains.

2. Affordable Power: Compared to other engine swaps or aftermarket builds, the B20B JDM engine is relatively affordable, making it an attractive option for those on a budget who still want strong performance.

3. Longevity and Reliability: Being a JDM engine, the B20B typically has low mileage, which makes it a reliable option for long-term use. The engine block is known for its strength and durability, making it a good investment for those planning to build a high-power setup.

4. Tuning Potential: The B20B offers excellent tuning potential, with the ability to handle significant modifications. Whether it’s for daily driving or high-performance racing, the B20B can be modified to suit a variety of driving styles.
