CP Piston & Ring Set for Nissan SR20DE w/ Turbo - Bore (87mm) - Size (+1.0mm) - CR (8.5)

If you're building a high-performance SR20DE engine for your 1989-1998 Nissan 240SX, especially one that will be force-fed by a turbocharger, a robust set of pistons is critical. These forged piston and ring sets from CP Pistons are designed to handle the increased stress and heat that come with boosted applications. They are a popular choice for enthusiasts looking to push their SR20DE engines beyond stock capabilities.

CP Pistons are well-known for their strength and reliability. These pistons are forged from high-grade aluminum alloys, which makes them significantly stronger and more durable than cast pistons. This forging process aligns the metal's grain structure, allowing them to withstand higher cylinder pressures and temperatures without deforming or failing. The set includes the necessary rings, which are also selected for their performance and durability in demanding conditions. This specific set features an 87mm bore, a +1.0mm oversize, and a compression ratio of 8.5:1, making it suitable for turbocharged setups where a slightly lower compression ratio helps prevent detonation under boost.

When rebuilding or upgrading your SR20DE engine, using pistons designed for the task is paramount. These CP Pistons are a solid option for anyone serious about building a reliable and powerful engine. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
