This ZRP 3353 cc Stroker Kit is designed for the Toyota Supra’s 3.0 L 2JZ-GTE engine, with the goal of increasing cubic capacity through a longer stroke and improving mechanical durability under high-load use (performance tuning, supercharging, endurance racing). The ZRP forged stroker crankshaft is made of 4340 steel and features a stroke of 94.00 mm. It is designed with a journal diameter of 61.994 mm and a crankpin diameter of 51.991 mm, for a specified weight of 22.30 kg. This configuration is designed to enhance rigidity and fatigue resistance compared to a standard crankshaft, while allowing for increased cubic capacity associated with a stroker mounting based on the 2JZ-GTE. The ZRP Pro Series forged I-profile connecting rods complete the set with geometry tailored to the 2JZ-GTE. They feature a center-to-center length of 142.00 mm, a gudgeon pin diameter of 22.00 mm, a conrod head diameter of 55.00 mm, and a conrod head width of 26.00 mm. The included fasteners are ARP L19 with a 3/8" thread to ensure reliable tightening and improved durability at high RPMs and under high combustion pressures. The kit also includes a Wiseco forged piston designed for the Toyota 3.0 L 2JZ Supra. Detailed piston specifications (bore, compression ratio, heat treatment, piston rings, recommended clearance) are not provided, but the inclusion of a forged piston is consistent with a stroker configuration designed for durability and dimensional stability under high thermal and mechanical stresses. Together, these components form a reinforced and cohesive internal foundation for a stroker mounting on a Toyota Supra 2JZ-GTE, focusing on lower-engine reliability and the ability to handle higher levels of torque and power, provided that the overall mounting (machining, balancing, clearances) and the choice of associated components are compatible.
