CP Piston & Ring Set for Honda B-Series - Bore (81.0mm) - Size (STD) - Compression Ratio (10.5)

Forged from high-strength 2618 aluminum alloy, these CP Pistons are built to handle the demands of a performance Honda B-Series engine. The 81.0mm bore size and 10.5:1 compression ratio are specifically chosen to work with the stock B-Series configuration, offering an improved power curve without requiring extensive modifications to the cylinder head or block. This set includes the pistons and the necessary rings, making it a complete package for a rebuild or performance upgrade.

CP Pistons are well-known for their robust construction and attention to detail. Each piston in this set features a specific skirt design and wrist pin bore to reduce friction and ensure smooth operation, even under high RPMs. The included rings are designed to seal effectively against the cylinder wall, maintaining consistent compression and preventing blow-by. This attention to detail means you can expect reliable performance and durability from this set, whether you're building a street car or a track-focused machine.

When rebuilding your B-Series engine with these pistons, it's important to ensure your cylinder block is properly honed to the 81.0mm bore specification. Proper ring gap setting and piston-to-wall clearance are critical for optimal performance and longevity. This set is a solid option for anyone looking to refresh or enhance their Integra's engine with well-made components.
