CP Piston & Ring Set for Nissan KA24 w/ Turbo - Bore (89.5mm) - Size (+0.5mm) - Compression Ratio (9

This kit includes a set of four forged pistons and matching piston rings, specifically made for the turbocharged KA24 engine found in the 1989-1998 Nissan 240SX. These aren't your average pistons; they're built to handle the increased stress and heat that come with turbocharging, offering a solid foundation for a performance build or a robust replacement for a worn-out engine.

CP Pistons is known for making well-built engine components, and this set is no exception. The pistons are forged from high-strength aluminum alloy, which is much stronger and more durable than cast aluminum. This means they can withstand higher cylinder pressures and temperatures without deforming or failing. The bore size is 89.5mm, which is a +0.5mm overbore from the stock size, ideal for engines that have already been bored out or need a slight increase in displacement. The compression ratio is listed at 9:1, a common target for turbocharged applications that balances power with reliability under boost.

When you're building or rebuilding an engine for performance, especially with a turbo, the pistons are one of the most critical components. These CP Pistons are designed to be a direct fit for your 240SX, meaning they should install without major modifications, assuming your engine block has been properly machined to the specified bore size. It's always a good idea to have your engine block professionally cleaned and inspected after machining before installing new pistons and rings.
