Honda 1.8L B18C VTEC Piston and Rod Set - Wiseco Molnar


Product Description

Set of forged Wiseco pistons and Molnar rods for Honda B18C1/C51, 1994-2001 Acura Integra Type-R. Wiseco pistons are CNC machined from a forged aluminum alloy, feature Wiseco's Armor Glide™ and Armor Plating™, valve pocket design, and crown shape. Wiseco pistons are made in the United States. Molnar H-beam connecting rods are made from 4340 steel, heat treated and shot peened. The rods feature bronze bushings and ARP2000 rod bolts. For all the piston options and specs of each view chart in description bellow. We try to have as much inventory as possible, but due to the large variety of pistons please contact us prior to purchase to confirm piston and rod availability and choose from drop down menu bellow. Free shipping to the United States (Alaska and Hawaii included) is via USPS Priority Mail.

Wiseco Pistons:

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 their Armor Glide™ coating to most sport compact pistons which reduces power robing friction. Select sets also have Wiseco's 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. 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.
