This ZRP 3295 cc Stroker Kit is designed for the Toyota Supra’s 3.0L 2JZ-GTE engine, with the goal of increasing engine cubic capacity via a stroker configuration and reinforcing the lower engine assembly for high-stress uses (performance tuning, supercharging, racing). The ZRP forged stroker crankshaft is made of 4340 steel and features a stroke of 94.00 mm. It is sized for the 2JZ-GTE with a journal diameter of 61.994 mm and a crankpin diameter of 51.991 mm. It has a weight of 22.30 kg. This design increases displacement while providing better mechanical strength than a standard crankshaft under high RPMs and loads. The ZRP Pro Series forged I-beam connecting rods are designed for the 2JZ-GTE and aim for high rigidity with a good balance between mass and resistance. They feature a center-to-center length of 142.00 mm, a piston pin diameter of 22.00 mm, a connecting rod top end diameter of 55.00 mm, and a head width of 26.00 mm. Each connecting rod weighs 0.63 kg. The included fasteners are ARP L19 with a 3/8" thread, suitable for demanding applications where tensile strength and clamping stability are critical. The package also includes a Wiseco forged piston for the Toyota 3.0L 2JZ Supra. Detailed specifications (dimensions, compression ratio, heat treatment, recommended clearance) are not provided. The inclusion of a forged piston complements the focus on reliability and thermal/mechanical strength expected in a stroker lower engine designed to withstand higher combustion pressures. This kit is designed for professionals seeking a comprehensive solution to build a performance-oriented 2JZ Supra lower engine, combining increased stroke, forged components, and high-performance fasteners to improve overall robustness and the ability to handle higher power levels. Not specified: final cubic capacity depends on bore, compression ratio, piston segments, shafts, main bearings, and mounting recommendations.
