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.
