CP Piston & Ring Set for Honda B-Series - Bore (84.5mm) - Size (+0.5mm) - Compression Ratio (9.7)

If you're rebuilding the heart of your 1988-2000 Honda Civic or 1994-1997 Acura Integra, especially for a performance build, a solid set of forged pistons is key. This CP Pistons set is built for B-series engines and features an 84.5mm bore with a +0.5mm oversize, designed to work with a 9.7:1 compression ratio. This is a popular choice when you need to refresh or upgrade your engine's internals for more power and reliability.

CP Pistons are well-known for their forged construction, which makes them significantly stronger and more durable than cast pistons. This strength is crucial for handling the increased cylinder pressures and temperatures that come with performance modifications or simply for ensuring long life in a rebuilt engine. The 84.5mm bore size means these are intended for engines that have been bored out by 0.5mm, a common practice during engine rebuilding to clean up cylinder walls or achieve a specific displacement. The 9.7:1 compression ratio offers a good balance, providing improved power output over stock without being so high that it requires extremely high octane fuel or specialized tuning, making it versatile for various build goals.

This set includes the pistons and the necessary rings to get your engine assembled. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when rebuilding your engine.
