Supertech Mazda Speed 2.3T 88mm Bore -14cc Dish 9.5:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is known for making well-built internal engine components, and these forged pistons for the Mazda Speed 2.3T are a prime example. If you're rebuilding or upgrading your engine, these pistons are designed to handle increased stress and performance demands. They feature an 88mm bore, a -14cc dish to help achieve a 9.5:1 compression ratio, and are sold as a set of four, excluding piston rings.

These pistons are forged from high-strength aluminum alloy, which offers a good balance of durability and weight savings compared to cast pistons. The dish volume is specifically calculated to work with the Mazda Speed 2.3T engine to achieve a 9.5:1 compression ratio, a popular target for modified engines seeking improved power without sacrificing too much drivability. This compression ratio is a solid choice for naturally aspirated or moderately boosted applications. Remember that piston rings are sold separately, so you'll need to source those to complete the installation.

When installing these pistons, it's crucial to follow the manufacturer's recommended clearances and procedures. Proper ring gap and bearing clearances are essential for the longevity and performance of your engine build. Due to their construction and intended use, these pistons are not CARB approved and cannot be shipped to California.
