The ZRP 1936 cm³ stroker kit with Wiseco pistons is designed for Audi and Volkswagen 1.8 Turbo 20-valve engines of the 06A type. It combines a stroker crankshaft, ZRP HD Series forged connecting rods, and Wiseco AP Series forged pistons for high-power engine builds.
The combination of a 92.8 mm stroke and an 81.50 mm bore increases the cubic capacity to 1936 cm³. The connecting rods have a center distance of 144.0 mm, with a stated compression ratio of 8.8:1 for this configuration.
The ZRP C-AUD-001L crankshaft is machined from solid 4340 steel. It is paired with ZRP R-AUD-006-I HD Series I-shaped connecting rods and Wiseco AP Series 23703-815 pistons, designed for applications subject to high mechanical stresses.

Mounting Information
This kit is intended for a bottom-end engine build. The bore and operating clearances must be checked and adjusted to the component specifications prior to assembly.
The compression ratio of 8.8:1 corresponds to the reference configuration, with a 1.35 mm thick, 83.00 mm diameter cylinder head gasket. The block geometry, combustion chamber volume, and actual piston positions must be verified during mounting.
