This ZRP 1984cc Stroker Kit is designed for base 06A Audi / Volkswagen 1.8L turbo 20V engines, with the goal of increasing cubic capacity and reinforcing the moving parts for high-performance use. The “stroker” configuration here features a stroker crankshaft, combined with forged connecting rods and forged pistons, to improve mechanical load capacity and high-RPM durability as part of an engine upgrade.
The ZRP forged stroker crankshaft is made of 4340 steel and is designed for VW Audi 1.8T 20V 06A applications. It features a stroke of 92.80 mm, with a journal diameter of 54.00 mm and a crankpin diameter of 47.80 mm. Its weight is listed at 13.80 kg. This configuration is designed to increase displacement and provide a more robust foundation than a standard crankshaft in setups with high torque and boost pressure.
The I-shaped forged ZRP connecting rods included in the kit are designed for Audi/Volkswagen 2.0 TFSI/TSI EA888 engines, with compatibility indicated by the engine codes BHZ, BYD, BZC, CDLA, CDLB, CDLC, CDLF, CDLG, CDMA, CDZA, and BWJ. They feature a center-to-center length of 144.00 mm, a gudgeon pin diameter of 21.00 mm, a conrod head diameter of 50.60 mm, and a conrod head width of 24.90 mm.
The included fasteners are made of ARP2000 with a 3/8" thread, for better resistance during tightening and increased resistance under heavy use. The listed weight is 0.51 kg per connecting rod.
The kit also includes Wiseco forged pistons designed for Audi/VW 1.8L turbo engines with 20 valves based on the 06A platform.
This kit is intended for professionals seeking a comprehensive solution to build a reinforced 1.8T 20V 06A lower engine in a 1984cc stroker configuration, combining forged components suited to the demands of a turbocharged setup.
