Supertech Nissan SR20DET 87mm Bore -10cc Dish 9:1 CR Pistons w/H13 Pin - Set of 4 (Excl Rings)

Forged from high-strength 4032 aluminum alloy, these Supertech pistons are built to handle the demands of a performance Nissan SR20DET engine. The -10cc dish volume, combined with the piston's dome shape, helps achieve a 9:1 compression ratio, which is a solid choice for boosted applications where you want a bit more control over detonation while still maintaining good power. The H13 tool steel wrist pins are included, known for their exceptional hardness and durability under high stress, making them a strong point for this set.

Each piston is precision-machined to an 87mm bore size, a common upgrade for SR20DET builds looking to increase displacement. The forged construction means these pistons are inherently stronger and more resistant to fatigue than cast pistons, which is crucial for engines that see higher cylinder pressures from turbocharging or increased boost levels. This set includes four pistons and their corresponding H13 wrist pins, ready for your engine build. Remember that piston rings are sold separately, so be sure to select a compatible set for your specific application to ensure proper sealing and performance.

When rebuilding or upgrading your SR20DET, choosing well-built internal components like these pistons is key to reliability and performance. Ensure you follow the manufacturer's recommended clearances and installation procedures for optimal results and longevity. These pistons are not CARB approved and cannot be shipped to California.
