Supertech Forged Pistons H13 Pins Nissan Bluebird X-Trail SR20VE 87.00mm -10 cc 9.6:1

Pistons are manufactured in Argentina with technology transferred from European manufacturers.

Our pistons are manufactured from extruded high silicon, enhanced 4032 alloy (with additional Cu, Ni & Mg) that has low thermal expansion, excellent wear resistance and higher thermal conductivity. Our pistons with this alloy have withstood up to 42psi of turbo boost, with alcohol, without any problems.

A 2 or 3 forging steps process yields a fine structural grain oriented in fibers in the same direction of the stresses.

Several heat treatments provide the piston with a high tensile strength and evenly distributed hardness. The pistons are submitted to several machining steps in specially designed machines and in conventional CNC. machines with special diamond tools for dimensional precision, perpendicularity and flatness of the ring grooves. Contact reduction grooves are standard. Honed & reamed pin bores for precise fit.

Wrist pins are constructed of H13 Tool Steel.

Finally our "phosphate dry lubricant" coating is applied to protect the rings against "micro welding" and enhance lubrication on the skirt/cylinder area.

Piston Rings are manufactured in Japan with the latest technology for high performance applications.

Quality Control: Performed after every step of the manufacturing process in climate controlled environments to ensure reliability of dimensions.
