CP Piston & Ring Set for Honda B-Series - Bore (85mm) - Size (+1.0mm) - Compression Ratio (9.0)

If you're rebuilding the heart of your 1988-2000 Honda Civic or 1994-1997 Acura Integra, especially with a B-series engine, a robust set of pistons is crucial. This CP Pistons set is built for performance applications where reliability under stress is key. These aren't just replacement parts; they're designed to handle more power and endure demanding use, making them a solid choice for engine builds aiming for improved output.

Crafted from forged aluminum, these pistons are notably stronger and more durable than cast pistons, which is essential when you're pushing an engine beyond its stock limits. The 85mm bore size, combined with a +1.0mm oversize, means these are intended for engines that have been bored out to accommodate them, typically during a performance rebuild. The 9.0:1 compression ratio is a balanced figure, suitable for a wide range of modifications, offering a good compromise between power and drivability without requiring extremely high octane fuel in most setups. This set includes the pistons and the necessary rings, simplifying your parts acquisition for the build.

When installing these pistons, remember they are an oversize component, meaning your engine block will need to be machined to the correct 85mm bore size. It's always recommended to consult your engine builder or a trusted mechanic for the precise machining specifications and installation procedures. This set is designed for performance builds and is not CARB approved, so it cannot be shipped to California.
