What is the compression ratio impact of the -12.00 CC dish?

The -12.00 CC dish volume is a key factor in determining your engine's final compression ratio. When combined with your cylinder head volume and head gasket thickness, it will lower the overall compression compared to a flat-top piston. You'll need to calculate this based on your specific components to achieve your desired compression target.

What material are the pistons made from?

These Manley pistons are forged from a domestic 2618 alloy. This material is chosen for its high strength and ability to withstand the extreme temperatures and pressures found in performance-oriented engines.

Are these pistons suitable for a stock SR20DE engine?

While these pistons are built with superior strength, they are often used in modified or performance SR20DE builds where increased power output is desired. For a stock rebuild, ensure the compression ratio achieved with the -12.00 CC dish is appropriate for your intended use.

About this part

Product Details

If you're rebuilding the heart of your Nissan SR20DE engine, Manley's Platinum Series piston set is a solid choice for serious performance. These pistons are built for the demands of high-output SR20DE applications, offering a direct replacement for your stock pistons but with significantly improved strength and durability. They feature a specific bore size of 86.25mm and a dish volume of -12.00 CC, which is important for setting your compression ratio correctly when paired with your cylinder head and gasket combination.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to handle high temperatures and pressures without deforming. This is crucial for engines that see hard use or are modified for more power. The pistons also come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring lands and skirt machining are perfectly square, which helps achieve a better ring seal and ultimately more power. You'll also find proven cam and barrel skirt profiles designed to reduce friction and wear on your cylinder walls, even under aggressive conditions.

This set includes everything you need to get your SR20DE engine rebuilt with robust internals. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer's instructions for proper installation and to ensure correct compression ratio with your chosen cylinder head and gasket combination.
