Overview
The 2JZ billet crankshaft with a 90mm stroke and standard journal sizes is a high-performance upgrade designed to enhance both strength and efficiency in Toyota 2JZ engine builds. Forged from 4340 billet steel, it offers exceptional durability, withstanding extreme RPM, boost pressure, and power levels typical in motorsport and high-horsepower street applications. The 90mm stroke increases engine displacement modestly while retaining high-revving responsiveness, making it ideal for balanced setups targeting both power and agility. Precision 5-axis CNC machining delivers exacting tolerances, while micropolished journals and chamfered oil holes promote superior lubrication and reduced bearing friction. The crank is internally balanced for smooth operation and features fully profiled counterweights to reduce windage and crankcase drag. Gun-drilled and cross-drilled oil passages improve oil delivery to critical areas under extreme load. Enhanced with nitriding, shot peening, and stress-relief treatments, and magnaflux inspected for structural integrity, this crankshaft is a top-tier solution for high-output, endurance-focused 2JZ builds.
