CP Piston & Ring Set for Nissan KA24 w/ Turbo - Bore (89.0mm) - Size (STD) - Compression Ratio (9.0)

If you're building a turbocharged Nissan KA24 engine for your 1989-1998 240SX, this forged piston and ring set from CP Pistons is a solid choice. These pistons are designed to handle the increased cylinder pressures and heat that come with turbocharging, offering a significant upgrade over stock cast pistons. They feature a standard bore size of 89.0mm and a 9.0:1 compression ratio, which is well-suited for boosted applications where you want to maintain reasonable compression for street drivability while still benefiting from turbo power.

CP Pistons are known for their robust construction. These are forged from high-strength aluminum alloy, making them much more resistant to detonation and mechanical stress than cast pistons. This durability is crucial when you're pushing an engine hard, especially with forced induction. The set includes the pistons and the necessary rings, all manufactured to tight tolerances to ensure a proper seal and efficient operation. The 9.0:1 compression ratio is a popular target for many turbo builds, offering a good balance between power output and the ability to run safely on pump gas with proper tuning.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper ring gap setting and cylinder wall preparation are key to their performance and longevity. This set is intended for enthusiasts looking to build a more powerful and reliable engine for their 240SX. Please note that this part is not CARB approved and cannot be shipped to California.
