I have just got my Audi V8 swap up and running in a 2003 boxster S.

Using a 2001 A8 engine. DBW, Can Bus all working on Audi ECU. Currently has a Cayman 5 speed mated to it.
Transmission in standard location, had to cut the engine bay and fab a new cover.
This is a race car, so not concerned about packaging as much as practicality. Air intake has been moved to the trunk for ease of install.
Running electric power steering and no AC. Just the alternator driven from the engine.
Threaded Mode
