Supertech Nissan SR20DET 86.5mm Bore -10cc Dish 9:1 CR Forged Pistons- Set of 4 (Excl Rings)

What you get in this box is a set of four Supertech forged pistons, each with an 86.5mm bore and a -10cc dish, designed to achieve a 9:1 compression ratio for your Nissan SR20DET engine. These pistons are built from strong, forged aluminum, which is a significant upgrade over cast pistons. Forged aluminum is much more resistant to the stresses of high performance and boosted applications, making it a solid choice for serious engine builds. The -10cc dish is specifically shaped to work with the SR20DET head to achieve that 9:1 compression ratio, which is a popular target for many performance builds, offering a good balance between power and reliability on pump gas.

These pistons are made to handle the demands of a performance SR20DET. The forged construction means they can withstand higher cylinder pressures and temperatures that come with increased boost or more aggressive tuning. While these pistons are a critical component for rebuilding or upgrading your SR20DET, remember that they do not include piston rings. You'll need to source compatible rings separately to complete the installation. It's also important to note that these pistons are not CARB approved and cannot be shipped to California.
