Supertech Honda D16Z 75.50mm Bore -3.3cc Dish 10.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Honda D16Z, a solid set of pistons is crucial for getting it back to running strong. These Supertech forged pistons are built to handle the demands of a refreshed D16Z engine, offering a reliable foundation for your build. They feature a 75.50mm bore size and a dish volume of -3.3cc, which works out to a 10.5:1 compression ratio. This compression level is a popular choice for many D16Z builds, providing a noticeable bump in performance over stock without requiring extreme modifications.

Forged pistons like these are made from a solid block of aluminum that's heated and hammered into shape, making them significantly stronger and more durable than cast pistons. This strength is important for handling increased cylinder pressures and temperatures, especially if you plan on running more boost or higher RPMs. The dish in the piston crown is carefully machined to achieve the target compression ratio when paired with the correct cylinder head. Remember that these pistons are sold as a set of four and do not include piston rings, so you'll need to source those separately to complete the installation.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper ring gap and bearing clearance are essential for the longevity of your engine rebuild. Since these are a specific size (75.50mm), ensure your cylinder bores are honed to match precisely. This set is not CARB approved and cannot be shipped to California.
