CP Piston & Ring Set Honda B20 w/B16 Head - Bore (84mm) - Size (STD) - Comp Ratio (10.2)

If you're building a high-performance Honda engine, especially one that combines a B20 block with a B16 head, a strong set of pistons is crucial. This CP Pistons set is designed for that specific combination, aiming for a 10.2:1 compression ratio with an 84mm bore. These aren't your everyday replacement pistons; they're built for demanding applications where reliability and performance under stress are key.

CP Pistons are well-known for their forged construction, which means they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, making them resistant to the higher pressures and temperatures found in modified engines. This particular set is a standard bore size (84mm), meaning it's intended for a fresh B20 block or one that has only been honed to its original size. The 10.2:1 compression ratio is a good balance for many performance builds, offering improved power without being so high that it requires exotic fuel in most setups. They come ready for your build, including the rings needed to seal the combustion chamber effectively.

When undertaking an engine build of this nature, it's important to ensure all components are compatible and properly installed. This piston set is a significant part of that equation, providing a solid foundation for your engine's power output. Remember that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation details and any other components you might need for your project.
