Supertech Nissan KA24 90mm (+1) 1.339in CH -27cc Dish 8.6:1 CR Piston - Set of 4 (Excl Rings)

Supertech is known for making well-built engine components, and this set of four forged pistons for the Nissan KA24 engine is no exception. If you're rebuilding or modifying your KA24, these pistons are designed to handle increased stress and performance demands. They feature a 90mm bore, which is a +1 size over stock, and a dish volume of -27cc, resulting in a compression ratio of 8.6:1. This makes them a solid choice for builds looking for a slight bump in compression without going too extreme.

These pistons are forged from high-strength aluminum alloy, a common practice for performance pistons because it offers a strong yet lightweight option that can withstand higher cylinder pressures and temperatures than cast pistons. The wrist pin height (CH) is 1.339 inches. It's important to note that this set does not include piston rings, so you'll need to purchase those separately to complete the installation. This is a common practice for performance builds, allowing you to select rings that best match your specific engine build and tuning goals.

When installing these pistons, always refer to the manufacturer's detailed installation instructions. Proper clearance, ring gap, and lubrication are critical for the longevity and performance of any engine build, especially when using aftermarket performance components like these. Because these pistons are not CARB approved, they cannot be shipped to California.
