CP Piston & Ring Set for Acura B18C1 - Bore (83mm) - Size (+2.0mm) - Compression Ratio (9.0)

If you're rebuilding the engine in your 1994-2001 Acura Integra, especially for a performance application or to address worn components, a solid set of pistons is crucial. This forged piston and ring set from CP Pistons is built for the B18C1 engine, offering a robust solution for your build. These pistons are designed to handle increased stress and heat, making them a popular choice for enthusiasts looking to get the most out of their Integra's powerplant.

CP Pistons are well-known for their forged construction, which starts with a block of aerospace-grade aluminum that is heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, which is essential when you're pushing an engine beyond its stock limits. This particular set features an 83mm bore, which is a +2.0mm oversize from the factory specification. This allows for a larger displacement and can help clean up cylinder walls that might have minor imperfections. The compression ratio is set at 9.0:1, which is a good balance for many performance applications, offering improved power without being overly sensitive to fuel octane in naturally aspirated setups.

This set includes the pistons and the necessary rings to complete the installation. When installing these oversize pistons, it's important to ensure your cylinders are properly bored and honed to the exact specifications for the +2.0mm size to ensure a good seal and proper piston-to-wall clearance. Always refer to the manufacturer's installation instructions for precise measurements and procedures. Please note that this part is not CARB approved and cannot be shipped to California.
