This 1936 cc ZRP Stroker Kit is designed for 06A-generation Audi/Volkswagen 1.8L Turbo 20V engines. It includes the essential lower-engine components for a performance-oriented stroker configuration, featuring forged and reinforced parts designed to withstand high mechanical stresses (load, RPM, boost pressure) during engine tuning.
The ZRP forged stroker crankshaft is made of 4340 steel and has a stroke of 92.80 mm. It is specified for Audi/Volkswagen 1.8T 20V applications (listed engine codes: 1.8T 20V and EA113) and is also listed as compatible with the 2.0 TFSI EA888 (to be considered based on your specific configuration, not specified in this kit).
The specified functional sizes are a journal diameter of 54.00 mm and a crankpin diameter of 47.80 mm, with a weight of 13.80 kg. This increase in stroke allows for greater cubic capacity and torque, while maintaining a reinforced cankshaft base suitable for heavy-duty use.
The included ZRP H-shaped forged connecting rods are designed for Audi/Volkswagen 1.8 20V turbo engines as well as the 2.0 TSI EA113, 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 conrod head diameter of 50.60 mm, and a conrod head width of 24.89 mm. The fasteners provided are made of ARP2000 with 3/8" threads, for increased strength during tightening and improved reliability under severe conditions. The listed weight is 0.45 kg per connecting rod. The H-shaped design is intended to improve rigidity and fatigue resistance, which is particularly useful in tuned turbocharged engines. The package also includes a ZRP Supersport forged piston for the Audi/Volkswagen 1.8L Turbo 20-valve 06A engine. Dimensional specifications and the compression ratio are not specified in the provided information; therefore, it is recommended to verify these parameters (dimensions, piston clearance, piston rings, compression height) based on the bore and intended mounting before assembly.
This kit is intended for professionals seeking a consistent base combination of a stroker crankshaft, forged connecting rods, and forged pistons to build a reinforced lower engine block for the Audi/Volkswagen 1.8T 20V 06A, with an expected increase in cubic capacity and torque, while ensuring the mechanical integrity of the moving parts.
