Description

Wiseco pistons go through more finishing processes than any other piston on the market without driving the cost up. They come with more features standard than any other piston on the market, at a more affordable price than many of the competitors. All of the Wiseco pistons for this application come standard with anti-friction skirt coating which helps minimize scuffing during break-in and lower friction on the cylinder wall. The top face of the piston is textured to improve the combustion characteristics, and all kits come with rings, pins and locks.

The Multivalve Piston Technology Leader

Wiseco is world renowned for their work building race winning pistons for compact engines featuring small bores, multi-valves, and high RPM applications for many years. Wiseco utilizes experience acquired from a diverse background of the most sophisticated engines in such venues as Formula 1, Indy Racing League (IRL), NHRA Pro Stock Bike, AMA Superbike, and AMA Motocross to design and manufacture the highest technology Sport Compact piston available.

1 Generous Valve Pocket designs that allow maximum flow around valve.
Note: Piston to valve clearance must be checked.

2 Piston Crown shapes designed to promote maximum Intake Charge efficiency thru scavenging mixture Cross Flow during intake and exhaust valve overlap. More fuel and air equals more horsepower!

3 Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

4 Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has added skirt coatings to the long list of standard features on our stocked Sport Compact pistons!

5 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.

6 World class forging facility that utilizes the latest technologies featuring complex forged shapes, advanced materials, and featured-aligned grain flow technology

1) Aerospace grade materials, forged for maximum strength.

2) Precision tolerance CNC machining for quality, repeatability and performance.

3) Crown thickness and ring lands designed for power adders like - forced induction (turbos & blowers) and nitrous oxide. Note: High compression pistons are generally designed for naturally aspired application.

4) High Quality Piston Rings featuring positive twist nitride steel top ring, Napier 2nd ring, and nitrided rails on a specially designed expander for the best oil control.

5) Wrist Pins constructed of chrome moly steel material for the ultimate in strength.

6) Honed/Reamed pin bore holes for a precise tolerance fit between wrist pin and piston.

7) Wire Retainer Clip Lock, featuring chrome silicon material for the ultimate yield strength.

8) Piston deburred for performance and reliability.

9) Piston weights listed may vary.

10) All specs based on U.S. engine codes unless noted.
