Supertech Mazdaspeed 2.3L 87.5mm Bore -14cc Dish 9.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Mazdaspeed with the 2.3L engine, these Supertech forged pistons are a solid option for handling increased power. This set includes four pistons, each measuring 87.5mm in bore diameter and featuring a -14cc dish to achieve a 9.5:1 compression ratio. Forged pistons are a significant upgrade over stock cast pistons, offering much greater strength and durability to withstand higher cylinder pressures and temperatures common in performance applications.

Supertech uses high-strength aluminum alloys for their pistons, which are forged to create a denser, more robust grain structure. This process makes them highly resistant to detonation and mechanical stress, crucial for engines that see track use or significant modifications. The 9.5:1 compression ratio is a popular choice for many performance builds, offering a good balance between power output and pump gas compatibility, though specific fuel requirements will depend on your engine's overall setup and tuning. Keep in mind that this set does not include piston rings, so you'll need to source those separately to complete the installation.

When installing these pistons, it's essential to follow the manufacturer's recommended clearances and lubrication procedures. Proper balancing of the rotating assembly is also critical for engine longevity. These pistons are designed for performance builds and require careful tuning to maximize their benefits and ensure reliability.
