This ZRP 3314 cc Stroker Kit is designed for the Toyota 3.0L 2JZ-GTE engine, specifically for the Toyota Supra, with the goal of increasing the engine’s cubic capacity and lower engine load as part of a high-performance build. The kit includes the main components required for conversion to a stroker configuration, prioritizing forged parts designed to withstand high stresses (boost pressure, sustained high RPMs, and increased torque). The ZRP forged stroker crankshaft is made of 4340 steel, a material renowned for its mechanical strength and fatigue resistance. It features a stroke of 94.00 mm, a key factor in increasing cubic capacity. The specified machining sizes are a journal diameter of 61.994 mm and a crankpin diameter of 51.991 mm, with a weight of 22.30 kg. This reinforced crankshaft is designed to improve the robustness and stability of the lower engine assembly on the 2JZ-GTE as loads and torque increase. The ZRP Pro Series forged I-Beam connecting rods are designed for the 2JZ-GTE and come with ARP L19 fasteners (3/8" thread), suitable for high-stress applications. The specified dimensions include a center-to-center length of 142.00 mm, a piston pin diameter of 22.00 mm, a conrod head diameter of 55.00 mm, and a conrod head width of 26.00 mm, for a unit weight of 0.63 kg. This geometry and forged design are intended to ensure mechanical reliability at high RPM and under high pressure, while maintaining sufficient rigidity for demanding engine builds. The package also includes a Wiseco forged piston for the Toyota 3.0L 2JZ Supra. Detailed specifications (dimensions, compression ratio, heat treatment(s), included piston rings, recommended clearance) are not specified in the context, but the inclusion of a forged piston is consistent with a performance-oriented stroker configuration, designed to accommodate the increase in cubic capacity and the associated thermomechanical stresses. This kit is intended for professional mounting requiring comprehensive metrological checks (clearances, alignments, balancing, and peripheral component compatibility) when assembling a stroker engine bottom end on a Toyota Supra 2JZ-GTE. Not specified: exact applications by year/chassis, cubic capacity achieved based on bore, final compression ratio, and any additional components that may be required (pistons, bearings, balancing, machining).
