Is the w12 not FSI? the newest 6.3l version is.
Are you planning on running stand alone, or wiring the factory computers in? A post above mentioned the amount of sensors, and I downloaded that self study pdf on the engine. Could you bypass some of the sensors if you were running a stand alone, or 2, one for each bank

Looking forward to this, if you actually go through with it.

side question, has anyone tried calling the phaeton owners hotline, would they speak to you if you are not a phaeton or w12 owner?

You can always go with a v10 tdi, but thats a rather heavy engine.
you could also get good power with larger snails and some tuning out of the 4l and 4.2l tdi engine, but again a cast v8 block weighs a lot

btw, why restrict yourself to vw/ audi engines, you can always go crazy and put a supercharged v8 form a benz, or their tt v12

i think page 28 might start to answer the question, although not very detailed

have you tried getting in touch with the guy on volksforum doing the fridolin w12? he could probably give you pointers/ tips on what to do for the wiring
