S6 C6 V10 manual swap

A6 All/ S6 All
#1

Hello,

Recently after going to meets, it solidified my idea of manual swapping my s6. Now I know its a monumnetal task to do something like that, and the part I dread the most is the coding for the car to recognize it. But I dont plan on getting rid of my S6 soon so it can stay un-driveable for a long time.

But back to the basics, I have a pretty detailed manual swap guide, but obviously with absolutely no information precise for the c6 s6, Im stuck at some prety basic steps, like what transmission would fit?

The 01E is pretty much the king of manual swaps in the Audi world, so it might be an option, but would it fight right onto the engine, or I would need like an adpater plate to bolt it down? Another thought I had is that since the 5.2 v10 is extremely similar to the 4.2 v8 with two more cylinders, would a manual transmission for it fit on the v10? Now if it can hold the power is another question too.

I’ve only really seen Jolio, rs6_jolio on instagram, do a similar thing, he manual swapped the v10, but swapped it entirely into a urs6 shell, but I’ve tried contacting him for info on his choice of transmission but he never responded.

I’ll need many more things, like:

  • Clutch master/slave cylinders
  • Clutch pedal assembly
  • Hydraulic lines for clutch
  • shifter and linkage
  • surround trim and shifter boot
  • front axles
  • Propshaft or trans/propshaft adapter
  • Rear differential
  • A 6 speed wiring harness to chop it up

And thats not counting what to do to cool the transmission fluid…

Like I said its a monumental task and a hassle, but I 100% believe it would be worth it. Just imagining a manual v10 makes my lower body heat up. The driving experience would be off the chart, and the car would be way lighter without the heavy automatic transmission.

Thanks for reading and hopefully helping me.

I know ECU wise you don’t have too much to worry about I know JHM has tuned a few swapped V10s.

I think the general take for the swaps to M are the old B5 transmission and that’s kinda a shitty transmission given all the other options. At least gearing wise. I think there was a guy who did the swap with a RS4 transmission. I’ll try to look and check back in with that to be sure. But I think the 4.2 V8 is a great way to go and I think the bell housing might be close if not fit. It’s likely to hold the power with no issues as the V10 isn’t going to make as much power as a supercharged 4.2 car and those transmissions hold up just fine with over 600whp.

Yeah, thats what I thought for the transmission, and thts great to hear that JHM could help, I just hope the price isnt steep…

and do you think the axles and the rear differential could be re-used with a manual transmission? obviously I think the prop shaft woulld now become too short since the automatic box seems way bigger and longer, so Ill probably have to have one made, but if I can save on a rear diff and axles, itd be nice.
