Supertech Nissan KA24 89mm Bore -11cc Dish 10.5:1 CR Pistons - Set of 4 (Excl Rings)

This set includes four Supertech pistons, each with an -11cc dish volume, designed for a 10.5:1 compression ratio in Nissan KA24 engines. These pistons are built for an 89mm bore and are sold without piston rings, so you'll need to source those separately. They are a well-built option for those rebuilding or upgrading their KA24 engine, aiming for improved performance and reliability.

Forged from high-strength aluminum alloy, these pistons are designed to withstand the increased pressures and temperatures common in performance applications. The -11cc dish is specifically engineered to achieve the 10.5:1 compression ratio when paired with the appropriate cylinder head and gasket combination. This compression ratio offers a good balance between power output and street drivability for many KA24 builds. The 89mm bore size is a common upgrade over the stock bore, allowing for increased displacement and potential power gains.

When installing these pistons, it's crucial to ensure proper clearance and fitment within the cylinder bore. Always refer to the manufacturer's detailed installation instructions for precise specifications, including ring gap, bearing clearances, and assembly procedures. Because these pistons are not CARB approved, they cannot be shipped to California. Please verify fitment for your specific engine build before ordering.
