CP Piston & Ring Set for Miata BPZ3 - Bore (83.5mm) - Size (+0.5mm) - Compression Ratio (9.0)

Starting with a bore size of 83.5mm and an oversize of +0.5mm, these CP Pistons are built for the 1999-2002 Mazda Miata. This set is designed to handle the demands of a performance-oriented engine, offering a 9.0:1 compression ratio that balances power with reliability for boosted applications or higher-performance naturally aspirated builds. CP Pistons are well-known in racing circles for their robust construction and attention to detail, making them a solid choice when you're rebuilding or upgrading your Miata's engine internals.

Forged from high-strength aluminum alloy, these pistons are significantly stronger and more durable than cast pistons. This material choice is crucial for withstanding the higher cylinder pressures and temperatures that come with performance tuning, especially if you're planning on adding a turbocharger or supercharger. The specific design of these pistons takes into account the BPZ3 engine's characteristics, ensuring proper fitment and function. Each piston is precision-machined to CP's exacting standards, which contributes to improved sealing and consistent performance across all cylinders. This level of detail helps ensure that your engine runs smoothly and efficiently, even under stress.

When undertaking an engine build of this caliber, it's important to ensure all supporting components are up to the task. This piston set is a critical piece of the puzzle for anyone looking to extract more power and durability from their Miata's engine. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
