Supertech Ford/Mazda 2.0L/2.3L 88mm Bore +7.8cc Dome 12.6:1/14.1:1 CR Pistons- Set of 4 (Excl Rings)

This is a set of four Supertech forged pistons designed for Ford and Mazda 2.0L and 2.3L engines. These pistons feature an 88mm bore and a domed top with a volume of +7.8cc, which results in a compression ratio of either 12.6:1 or 14.1:1, depending on your cylinder head volume. This significant increase in compression is intended for performance builds where higher octane fuel is used, aiming to extract more power from the engine. The pistons are made from high-strength aluminum alloy for durability under demanding conditions.

Supertech uses a forging process for these pistons, which creates a denser, stronger grain structure compared to cast pistons. This makes them more resistant to the high pressures and temperatures generated in a performance engine. The 88mm bore size is a common upgrade for these engines, allowing for a slight increase in displacement. It's important to note that these pistons are sold without piston rings, so you will need to source those separately. Ensure you select rings compatible with the 88mm bore and the specific ring groove dimensions of these pistons.

When rebuilding an engine with these high-compression pistons, careful attention must be paid to cylinder head porting, camshaft selection, and tuning to maximize performance and ensure engine reliability. Due to the increased compression ratio, these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or a qualified performance tuner to ensure these pistons are the right choice for your specific build and that all supporting modifications are made correctly.
