Almost positive you can use the SteveKen adapter kit for the trans. The wiring shouldn't be tough, the technology isn't that advanced for an 04ish car. Just use the W12 cluster and wire it up correctly.

The technology IS very advanced, even on a 2001 D2 6,0 A8L. The cluster's just a minute part of the jigsaw. To run the W12 cluster, you'll need to have pretty much the whole wiring, or at least the main (central) one, which is the dash harness.

I've rewired a D2 6,0 W12 that had suffered a minor dash fire. It took close to 4 weeks to get it up and running, making a new harness. Bear in mind, this car actually came with a 6,0 W12, yet it was a pig to rewire, and fought back every step of the way. After she ran, it took me a further week to eliminate bugs that had the cluster glowing like a Christmas tree.

It's not an easy job.

Kind of late to the conversation, but why not use a 1.9 TDI engine and power adders (bigger turbo, injectors & chip) Can easily make big HP and Torque numbers, is a very small power plant and trans choices are large..

Kind of like this http://www.youtube.com/watch?v=2vLOcva5 ... re=related" onclick="window.open(this.href);return false;

1) Limited rev range.
2) Sound - very flat, lacks "soul."
3) Power delivery.
4) Cost. Diesel's a lot more expensive in the UK than gasoline.
5) Lots of black smoke under full-bore throttle, more so once modified with bigger turbo and injector nozzles.

:? Even I wouldn't suggest a 1.9 TDI to someone who was considering a W12 It'll 'easily' make 200hp / 300lb-ft but beyond that it gets pretty expensive. Not sure anyone has managed 440hp from one!

Now a V8 TDI would be a different kettle of fish entirely, but thats probably a whole other thread :wink:

I second all the above.

It's like suggesting a 1,8T Audi A4 B6 to someone who's considering a Bugatti Veyron. It's a non-starter. :?

People buy diesel-engined cars for their miserly fuel consumption. A 1,9 TDI tuned from 130/150 hp to 200 and beyond, with a fatter snail and bigger injectors will be thirsty. Couple that to the higher initial investment (purchase price) and the higher cost of derv, then suddenly the sensible diesel becomes impractical.

To each his (or her) own.. I have serveral very good friends with a MKIV Golf's (1.9PD) that is easily 200HP but +300Lb/Ft torque as their daily drivers get 50+MPG.. with lots more things that could be done for penny's on the dollar compared to the investment of a W12 +trans +100's of hours of fab work not to mention the 100's of hours of wiring - Just sayin.

I agree the mpg of a tuned 1,9 TDI will be higher than that of a stock 6,0 W12. But one thing's for sure - the OP must know he can't expect brilliant gas mileage out of a 6,0 engine. So I doubt mpg is really an issue here.

100's of hours of fabrication work to get a W12 into a VW Bug? That's part of the fun, a unique ride isn't simply a bolt-together job, otherwise everyone would be doing it.

Personally, the 1,9 PD option doesn't do it for me. I also run a 2008 BMW 118D (2,0 turbo diesel). It's okay-ish.But not comparable to a big gas engine. The enjoyment element comes into things, in most cases above mpg. The flat monotone of a 4 banger diesel can never match the soundtrack of a highly-tuned I5/V6/V8/V10/W12 etc. It just doesn't.

Lastly, if gas mileage was the greatest deciding factor, most of us here would not be tuning our gas engines to produce big power, and guzzling more gas. We'd be leaving them stock, and probably be running Volkswagen Polo I3 TDI or similar.

^^^ That's the spirit!

Were you able to sort out a fuel pump for the S8?

So how many wires go to the motor? Can't be more than like 50. Most of them are like "oil low light" or coolant temp. The only real input that the motor sees is the throttle and power

If only it was that straight forward, but it's not.

 

[Nollywood]

So what other inputs does the motor see? How many wires go through the harness plugs?

Bud, I'd have to be an anorak to remember how many wires go through the harness plug. I honestly can't remember, I do a job, then put my mind back on family issues. Without looking at a D2 6,0 W12, or at least the wiring schematic, I couldn't answer your question.

Mickey, the W12 crank shares the same 10-bolt fitment to flexiplate with the original Audi V8, D2 32V, VR6 and RS6. All have the same PCD. However, the W12 flexiplate takes a larger torque converter than an ABZ, so I very much doubt if the 034 insert will fit.

Volkswagen Touareg 3,2 VR6 6-speed manual has a 10-bolt crank...the flywheel is a direct bolt-on affair to the 6,0 V12...
