I researched this a long time ago, about 2 months I believe. If you do a Dahlback type install (move everything to the back: battery, radiator, what not) it's feasible. I have a post around here about it. I'd rather have a turbo 24V VR6 though.
The W8 is heavier than your average V8. This b/c of balance axles [bad Dutch translation] and stuff. So expect understeer like you've never seen before.
On the bright side. This is a 4.2l V8 in the Audi A3 hatchback, which shares its platform with the Bora:
If your going to pull a dahlback, than you can put pritty much fit any engine you want in your car. but then again, if your going to buy that incredibly expensive engine and then customise your hole car why don't you just use an engine from a ferrari because aparently your a millionaire.
