Wiseco utilizes experience acquired from a diverse background of the most sophisticated engines in such venues as Formula 1, Indy Car Racing, NHRA Pro Stock Bike, AMA Superbike, and AMA Motocross to design and manufacture the highest technology Sport Compact piston available. Generous Valve Pocket designs that allow maximum flow around valve. Note: Piston to valve clearance must be checked. Piston Crown shapes designed to promote maximum Intake Charge efficiency thru scavenging mixture ÒCross FlowÓ during intake and exhaust valve overlap. Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal.  Precision machined ring grooves with proper orifice / accumulator volume using calculated groove root diameters and axial widths, featuring excellent surface finish and flatness providing maximum ring seal and minimizes blow-by and oil consumption. World class forging facility that utilizes the latest technologies featuring complex forged shapes, advanced materials, and featured-aligned grain flow technology. Piston weights listed may vary. All specs based on U.S. engine codes unless noted. All Sport Compact pistons sold complete with rings, pins, and clips Part #:K678M865AP Applications: Toyota 2JZGTE 3.0L 24V Supra 1993-98.
