Wiseco 1400HD Forged Pistons Evo 4-9 (2.3L)

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.

2618 Alloy: The strongest alloy available with the best strength at high temperature and low silicon content, for low porosity.

Heavy Radii: Creating a large smooth radii from the skirts and pin boss into the crown prevents flex and cracking.
