Wiseco Sport Compact Forged Pistons:
Wiseco Sport Compact pistons are made from dedicated forgings produced in-house to give you a light weight piston with superior strength and optimal design. Being the multivalve piston technology leader, the line features specially designed valve pockets, complex dome and crown shapes, the steel nitride/napier xx rings and optimized skirt profiles. The pistons come standard with ArmorGlide® coating material for reduced friction and noise, freeing up horsepower.

This new strutted 1400HD forging has been developed for turbocharged methanol Mitsubishi 4G63 engines, making 350+ horsepower per cylinder. Got a large aftermarket turbo, tubular manifold, high compression, nitrous, and methanol injection? - no problem. The forging has been designed around special 21mm and 22mm tool steel pins of .225" wall thickness.
