Audi 4.2 V8 - Engine

[Mjpmark]

Hi guys,

In the process of sourcing an Audi 4.2 V8 from an S6 / S8.
Firstly does anyone have any contacts for new, if so any idea of cost?

Secondly i have potentially sourced a used one, however i need it re conditioning to new for SVA approval.
Does anyone know what this would cost or inded anyone local to the west midlands that could do the job.

Thanks in advance.

Mark
