This ZRP 2171cc Stroker Kit is designed for Toyota 2.0L 3S-GTE and 3S-GE engines, particularly in the Toyota Celica. It is intended to increase cubic capacity through a longer stroke, thereby improving torque potential and the engine’s ability to withstand demanding modifications, while utilizing forged components suitable for heavy-duty use. The ZRP forged stroker crankshaft is made of 4340 steel and features a stroke of 93.00 mm. It is sized with a journal diameter of 55.00 mm and a crankpin diameter of 48.00 mm. It weighs 17.20 kg. This component forms the basis of the stroker setup by increasing the stroke, with the goal of achieving greater strength and superior mechanical durability compared to a standard configuration, as part of a Toyota 3S-GTE / 3S-GE engine build. The ZRP forged I-beam connecting rods, of the reinforced type, are designed for Toyota 3S-GTE and 3S-GE engines. They feature a center-to-center length of 138.00 mm, a piston pin diameter of 22.00 mm, a conrod head diameter of 51.00 mm, and a conrod head width of 26.70 mm. Each conrod weighs 0.59 kg. The included fasteners are made of ARP2000 with a 3/8" thread to ensure reliable tightening and resistance suitable for the high stresses (load, RPM, boost pressure) typical of Toyota Celica 3S-GTE modifications. The package also includes a ZRP Supersport forged piston designed for the Toyota 2.0L 3S-GTE Celica. Detailed specifications for the piston (bore, compression ratio, heat treatment, piston rings, recommended clearance) are not provided. This component completes the stroker kit by ensuring compatibility with a reinforced configuration designed for performance and mechanical durability. This kit is intended for professionals seeking a cohesive solution to build a 2171cc stroker engine based on the Toyota 3S-GTE / 3S-GE (Toyota Celica), with forged parts and key sizes already defined for the crankshaft and connecting rods. Mounting and metrological checks (clearances, balancing, peripheral compatibility) must be performed in accordance with workshop practices and engine specifications.
