"One" of my Audi A5 gearboxes arrived today, all your fault Ross, i'm buying them in bulk!
The great news is this box weighs a lot less than my A4 box in my Mk1, i wish this had been around when i was doing that project, i reckon it's a good 20kgs lighter. The first thing that's very apparent is the diff area, i am going to have to remove engine block material in this area on the V12 (V8 looks like it will need modifying too), but it shouldn't be a huge problem.
Some dimensions for the tranny whores...
Oops! wrong link! That'll teach me for typing tranny whore into google
The middle of the output shafts are 45mm from the bellhousing face, now i have estimated i will need a 1" thick adapter plate on the V12, but the shafts sit 7" further forward on this box than the older A4 unit, so by my maths i am gaining 4.25" of space by using this gearbox, that's a huge amount. It also means on a V8 swap i gain 5.25", that definately puts the Audi V8 inside the engine bay without having to cut the front wall (at least at the bottom of it and should only need a top access panel if that)
So, so far it's all good news, although there is a very long way to go.
