Supertech Mazda Miata 1.6L 79.0 mm Bore -3.7cc Flat Top 10.6:1 CR Pistons - Set of 4 (Excl Rings)

This is a set of four Supertech forged pistons designed specifically for the 1.6L Mazda Miata engine. These pistons feature a 79.0 mm bore and a flat-top design with a -3.7cc dish, resulting in a 10.6:1 compression ratio. This setup is ideal for rebuilding or upgrading your Miata's engine, aiming for improved performance and responsiveness.

Forged pistons are a significant step up from cast pistons. They are made from a solid block of aluminum that is heated and hammered into shape, making them much stronger and more durable. This strength is crucial for handling the increased pressures and temperatures found in a performance-oriented engine. The 79.0 mm bore is the standard size for many 1.6L Miata engines, ensuring a proper fit within the cylinder walls. The 10.6:1 compression ratio is a popular choice for naturally aspirated builds, offering a noticeable bump in power without requiring exotic fuel or extensive engine management modifications. Keep in mind that this set does not include piston rings, so you will need to source those separately.

When rebuilding your engine, it's important to ensure all components are clean and properly lubricated. These pistons are designed to work with your existing connecting rods, but it's always a good idea to check rod bearing clearances and ensure the crankshaft is within specification. Proper installation and attention to detail during the engine assembly process will ensure these pistons perform as intended for many miles to come.
