Wiseco Asymmetric Pistons include .040" deeper pockets and .200" STEEL PINS!

We have been recommending Wiseco pistons for the 2JZ motors for a number of years now as an option to CP or JE. A professionally assembled 2JZ with Wiseco Pistons and good rods will handle 1000 HP in a well-tuned car, no problem.

These are proven the world over in 2JZ's. There are some other positives as well, with the highest quality forging equipment and tooling in the industry, as well as factory side skirt coating at no additional cost, Wiseco is an excellent option. Save some $$.

Wiseco has been one of the most trusted names in the racing industry since before most of our cars were even built. There is a reason why they are recognized across the world as the most popular solution for an affordable engine build that will handle high power output.

These Wiseco Pistons come standard with skirt coating for anti-friction. This provides a smoother break-in and a better sealing engine. If you notice the surface finish on the top of a Wiseco piston, it is carefully crafted that way to help with combustion characteristics. This is something you don't see in other brands.

The Multivalve Piston Technology Leader

Wiseco is world renowned for their work building race winning pistons for sport 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 Formula1, Indy Racing League (IRL), NHRA Pro Stock Bike, AMA Superbike, and AMA Motocross to design and manufacture the highest technology Sport Compact piston available.

Valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized.

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!

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

Wiseco's 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 shelf stock Sport Compact pistons!

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 thus minimizing blow-by and oil consumption.

Wiseco’s world class forging facility that utilizes the latest technologies featuring complex forging shapes, advanced materials and features aligned grain flow technology.

The pistons come with Rings, Pins, and Locks (six pistons).
