Wiseco has become world renowned for their work designing and manufacturing high performance pistons for Japanese multi-valve, high RPM applications. Now the company has produced forged piston sets for use in the 4B11-T engine as used in the Mitsubish Evo 10.

Wiseco forged pistons are ideal where the rev limit is going to be raised. When the rev limit is increased the stresses placed on the piston rise massively and it is in these situations when the forged piston will come into its own.

In addition Wiseco pistons also offer other benefits
Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilised.
Piston Crown shape designed to improve “Cross Flow” scavenging during intake and exhaust valve overlap. More fuel and air equals more horsepower!
Pistons designed to improve resistance to detonation and pre-ignition which in turn improves engine life and increases horsepower potential.
Complex Piston skirt profiles that reduce friction and promotes stability in bore for optimum ring seal.

The pistons are available in standard bore and +0.5, +1 and +2.
