This ZRP 1984cc Stroker Kit is designed for Audi / Volkswagen 1.8L Turbo 20V engines of the 06A generation, with a design focused on performance tuning and reliability for high-stress applications (supercharging, high engine revs, and significant thermal loads). The kit includes the main moving parts required for a “stroker” configuration designed to increase cubic capacity to 1984cc, while reinforcing the mechanical strength of the lower engine.
The ZRP forged stroker crankshaft is made of 4340 steel and features a stroke of 92.80 mm. It is listed as compatible with VW/Audi 1.8T 20V (EA113) engines as well as the 2.0 TFSI EA888 (compatibility noted in the context). Its key sizes include a journal diameter of 54.00 mm and a crankpin diameter of 47.80 mm, with a weight of 13.80 kg. This configuration is designed to improve torsional and fatigue resistance while allowing for the increased stroke required for the stroker conversion.
The ZRP Type I forged connecting rods (I-shaped connecting rods) are designed for Audi/Volkswagen 1.8 20V Turbo and 2.0 TSI EA113 engines, with an extensive list of compatible engine codes (AVC, ANB, AWU, AEB, APX, APY, BAM, AMK, AWM, AGU, AXX, BHZ, BGB, BWE, BUL, CDNB, BYK, BPJ, BWA, BWT). They feature a center-to-center length of 144.00 mm, a piston pin diameter of 20.00 mm, a connecting rod top end diameter of 50.60 mm, and a conrod head width of 24.89 mm.
The fasteners provided are made of ARP2000 with a 3/8" thread to increase clamping strength and safety during heavy-duty use. The specified weight is 0.52 kg (value provided in the context). The package also includes ZRP Supersport forged pistons designed for AUDI / VW 1.8L Turbo 20-valve engines in the 06A series. Detailed dimensional specifications for the piston (bore, compression ratio, segments, recommended clearance) are not specified in the context; however, the intended purpose is to complete the moving assembly with a forged solution suitable for high-performance and durable tuning.
This kit is intended for professionals seeking a reinforced and consistent lower-engine base for a stroker mounting on Audi/Volkswagen 1.8T 20V 06A engines, combining a forged crankshaft with increased stroke, reinforced forged connecting rods, and forged pistons to improve overall robustness against torque and boost pressure stresses.
