Modify Audi 7A 20v Cylinder Head to Turbo Specification

We can machine your Audi 7A 20v cylinder head to convert it to turbo specification, or modify your 3B or RR cylinder head to ABY/ADU/AAN specification by adding the cam/sync sensor mounting boss to the front of the cylinder head.

Firstly we drill & tap the mounting holes and mill the water ports into the intake side of the head to prepare for the turbo water flange. The ports are chamfered to aid install without damaging the fragile o-rings.

Next a shallow pocket is milled into the front face of the head to receive a machined boss with the locating dowel and mounting holes for the cam/sync sensor. The is fixed using M4 socket cap screws and sealing in place with high temperature RTV sealant.

All works are carried out to a high standard of accuracy on CNC machinery.
