SR20 Standard Stroke Pistons

For custom piston orders, please contact a us sales@hioctanediect.com

Our whole piston range is manufactured by CP Carrillo, based in California, USA. CP Carrillo are a subsidiary of Pankl Racing who are an Austrian automotive components manufacturer that manufacture components for the highest levels of motorsport including Formula 1, Le Mans Prototypes and Moto GP just to name a few. This means that every Nitto piston benefits from world leading technologies and processes that are passed from Pankl onto CP.

Nitto pistons are made to our own specifications in conjunction with CP Carrillo and are cut from CP’s low silicon content 2618 aluminium and Turbo HD forging (where applicable). Additionally, our pistons are accompanied by a PVD coated ring set which deliver the best bore sealing capabilities for boosted applications, eliminating virtually all blow by while reducing the friction against the cylinder wall. As part of the piston kit, CP’s upgraded 9310 material wrist pins are standard across our range. The pins are 100% Rockwell tested, case hardened and cryogenically treated in order to enhance their material grain structure and overall strength.

All Nitto pistons also come standard with additional features such as forced double pin oiling which is essential to keep the wrist pin well lubricated. Anti-detonation grooves are also included. Anti detonation grooves reduce piston to wall contact under high load and also protect the top ring by disrupting the detonation waves. Finally, another feature that is standard across our piston range are the accumulator grooves. Accumulator grooves accumulate residual gasses from combustion which alleviate top ring flutter and premature second ring wear, improving ring seal.

All of these features combine to create the world beating pistons that boast multiple world records across multiple categories in drag racing and circuit racing.

• T6 2618 FORGED ALUMINIUM ALLOY LOW SILICONE CONTENT MATERIAL
• High silicone content pistons (typically A4032 alloy) are a harder material but brittle when compared to the T6 2618 low silicone content pistons and leave them open to increased failure under high combustion pressures found in moderate to hard tuned turbocharged performance engines. High silicone content pistons also have a faster failure rate should severe detonation occur.
• CONTACT REDUTION GROOVES
• A series of small grooves machined into the piston area between the outer edge of the crown and the first ring land which reduces piston to bore friction and increases horse power and durability.
• ACCUMULATOR GROOVE
• A large vee shaped groove machined into the piston area between the first and second ring land, minimising power robbing ring flutter under high RPM resulting in increased combustion pressure sealing and engine power levels.
• 9310 TOOL STEEL PISTON PINS
• Upgraded high quality / high strength piston pins that offer further reliability in the transmission of large torque and horsepower levels.
