CP Piston & Ring Set for Acura B18C1 - Bore (82.0mm) - Size (+1.0mm) - Compression Ratio (9.0)

CP Pistons is well-known for making strong internal engine components, and this forged piston and ring set is a prime example of their work for the 1994-2001 Acura Integra. If you're rebuilding the engine in your B18C1, this set is designed to handle the demands of a performance build. It features a bore size of 82.0mm and is 1.0mm oversize, meaning it's intended for engines that have been bored out to accommodate this larger size, often during a rebuild to refresh worn cylinders or increase displacement. The compression ratio is set at 9.0:1, which is a solid figure for a naturally aspirated or moderately boosted setup, offering a good balance between power and reliability.

These pistons are forged, a process that makes them notably strong and durable compared to cast pistons. This strength is crucial for maintaining engine integrity under higher pressures and temperatures that come with performance tuning. The set includes the necessary rings, which are essential for proper sealing between the piston and cylinder wall, ensuring optimal compression and oil control. Because these are an oversize set, they are intended for use in engines that have already been machined to the 82.0mm bore size. This is a key consideration for your engine build; ensure your machine shop is aware of the required bore dimensions before installation.

When undertaking an engine rebuild of this caliber, it's important to have all the necessary supporting components ready. This piston set is a critical piece for refreshing or enhancing your B18C1 engine. Remember that this part cannot be shipped to California due to CARB regulations.
