Supertech Nissan KA24 89.5mm Bore 1.339in Comp Height -29cc Dish 8.4:1 CR Pistons - Set of 4

If you're rebuilding the engine in your Nissan KA24-powered vehicle, a solid set of pistons is crucial for performance and reliability. These Supertech forged pistons are built to handle the demands of a performance engine build, offering a robust upgrade over stock cast pistons. They feature an 89.5mm bore, which is a common size for engine overhauls, and a compression height of 1.339 inches. The -29cc dish volume helps achieve a specific compression ratio, in this case, 8.4:1, which is well-suited for naturally aspirated or boosted applications where controlled compression is key.

Forged pistons 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 essential for withstanding higher cylinder pressures and temperatures, especially in modified engines. Supertech is known for producing well-built internal engine components, and these pistons are no exception. They are designed to fit right into your KA24 engine, assuming the block has been machined to the 89.5mm bore size. This set includes four pistons, rings, and wrist pins, providing a complete package for one cylinder bank.

When installing these pistons, ensure your engine block has been properly honed to the correct bore size and that all clearances are checked according to the manufacturer's specifications. Proper balancing of the rotating assembly, including these new pistons, is also recommended for smooth operation and longevity. This set is a popular choice for enthusiasts looking to build a reliable and powerful KA24 engine.
