This turbo adapter lets you bolt a GTB family turbo to a longitudinal AFN/BHW passat or euro market 2.0L TDI common rail Audi A4/A6 exhaust manifold. No grinding on the exhaust manifold is required as the adapter is 3D profiled to match both the manifold and turbo. CNC machined in house from Dura-Bar cast iron bar stock. 

Includes laser cut copper gaskets, bolts, and Nord-Lok washers.
