Audi A5 Quattro gearbox,
First & only gearbox that has the front diff mounted this far forward.
Meaning that the engine sit's just in front of the axle as the axle centre line will be 1" behind the axle.
All other quattro box's would have meant the engine sat to far forward and that would mean this conversion
would not be possible as the front evo ix support panel is already mounted 4" further back.



Surprisingly compact 6 cylinder. any other engine also would not have fit as a 4 cylinder inline would
be too far forward also & V8 is just overkill too much weight overhang etc etc.

This engine with a hybrid turbo & remap is know to put out 320hp & 550ft-lbs.
in a small hatchback & still return 40-50mpg when driven conservatively :)
