Toyota Corolla 3TC (with 63cc head) Custom 89mm 14.2:1 Piston Set .160 Over - K686M89AP


Product Description

Toyota 1.8L 3TC 89mm piston set .160" over factory bore. 14.2:1 compression ratio. Pistons are forged and CNC machined, feature Wiseco's Valve Pocket Design which maximizes flow around valves and allows use of oversize valves and high lift camshafts; complex pistons crown shapes designed to promote maximum intake charge efficiency through cross flow during intake and exhaust valve overlap. Complex Piston skirt profiles reduce power robbing friction, prolong piston life, and increase horsepower. The pistons also feature Wiseco's Armor Glide™ on the skirt which minimizes friction, improves wear resistance, and helps increase power; and Wiseco Armor Plating™ which reduces heat on the dome, reduces the effects of detonation, and creates a hard yet smooth surface for the rings to rest on. Please note that these pistons are not stocked, please allow 3 weeks for them to be ready once payment is made.

On and off the street, you can depend on the maximum strength and minimum variance of Wiseco's aluminum-forged pistons for your sport compact vehicle. Wiseco's pistons outgun cast and hypereutectic pistons, giving you stronger pistons and tighter tolerances than any other part in your engine, with less internal and external machining. The advanced forging, extensive heat-treat, and finishing process assure you of the performance and reliability you demand from your engine.

Wiseco sport compact pistons feature Generous Valve Pocket Design that allow maximum flow around valve; and Piston Crown shapes designed to promote maximum intake charge efficiency through scavenging mixture "Cross Flow' during intake and exhaust valve overlap, which equates to more fuel and air, thus more horsepower. Wiseco pistons are also designed to optimize squish or quench during the compression-combustion cycle, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential. Additionally, the pistons feature Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has also added Armor Glide™ coating to most sport compact pistons. Every piston features precision CNC machined ring grooves with proper orifice/accumulator volume using calculated groove root diameters and axial widths, and have excellent surface finish and flatness providing maximum ring seal that minimizes blow-by and oil consumption. Finally, Wiseco utilizes the latest technologies featuring forged shapes, advanced materials, and featured aligned grain flow technology, in their world class forging facility.
