Supertech Ford/Mazda 2.3L 87.5mm Bore +1.5cc Dome 12.5:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is known for making well-built engine components, and these forged pistons for the Ford/Mazda 2.3L engine are a prime example. If you're looking to rebuild or significantly upgrade your engine's performance, especially for boosted applications or higher compression builds, these pistons are designed to handle the extra stress. They feature a specific dome volume of +1.5cc, which, when combined with the correct head gasket and cylinder head, helps achieve a 12.5:1 compression ratio. This higher compression can lead to improved power and throttle response.

These pistons are forged from high-strength aluminum, a process that creates a much stronger and more durable piston than cast alternatives. This makes them ideal for engines that will see hard use or are being built for increased power output. The 87.5mm bore size is a specific measurement, ensuring a precise fit within the cylinder. It's important to note that this set is for four pistons and does not include piston rings, so you'll need to source those separately to complete the installation. This is a common practice for performance builds, allowing tuners to select specific ring sets that match their exact needs.

When undertaking an engine rebuild with performance pistons like these, it's crucial to ensure all related components are up to spec. This includes the cylinder head, crankshaft, connecting rods, and the proper ring set. Always refer to the manufacturer's installation instructions for precise measurements, clearances, and assembly procedures to ensure optimal performance and longevity of your engine build. Please be aware that these pistons are not CARB approved and cannot be shipped to California.
