S6 to RS6 engine swap possible in US?

[IrishCreamPuff]

So I found a website that allows me to buy used RS6 V10 TT engines in the UK for roughly $6.5k. Is transplanting it into a C6 S6 feasible without tons of creative modification? I know it's kind of a really open ended question, but if all goes well I would LOVE to try this. A 6 second 0-60 time for a V10 is really starting to piss me off. Any idea what other parts I would need? New tranny? New propshaft?
Sorry for my ignorance!

No one has done it that I know of. However, I'd guess that it's fairly simple as long as the engine comes with ECU and harness. Probably some minor wiring involved, but physically everything should bolt up.

I'm not sure how much power the S6 transmission can handle.

Whats wrong with your S6 that you are running a 6 second 0-60? I ran a 4.88 in mine with apr stage 1 (only 20 hp) and a modded exhaust, rest of the car stock.

Much easier project to make the S6 faster is to go lightweight wheels, BBK (weight reduction) and APR stage 1 and you will be a in a noticeably better place.

No idea why, it just isn't that fast. Any other weight reductions I can make short of removing the rear seats?

Well...since your name is IrishCreamPuff I would say start with by dropping a few pounds yourself ;)

Lol I kid, I kid

Carbon deposits. The engine can't breathe.

6sec for a v10 is sad.

[Treedancer72]

My diesel does it in 6,4 so an s6 should be much faster. :)

Swap a 3.0T, will be faster, no import charges, etc

From what I've read, A6/S6/RS6 all sport the identical ZF 6 speed. Not positive but if that's the case, looks like this transmission is up for some serious power.

Already got a carbon clean 6 months ago.

With the APR stage 1, are you pretty much forced to use 93-95 octane? I do already, I'm just curious. Also do you have any idea how much resonator deletes cost?

[IanCH]

I ran 91 when I was in Maine without any problems, threw an octane booster in on one of the tanks and didn't see a noticeable difference. Ran shell 93 the rest of the time.

My resonator delete replaced with tig welded stainless cost a little over 200, can't remember the exact price, but I did all 4. If you search s6 quad resonator delete on YouTube you can find the video before and after of my car.

With the resonator delete, was there unbearable humming at cruising speed at all?

[z06psi]

Remote mount turbos would do wonders for this car in place of the rear resonators. Also a little N2O in each airbox does the trick too. 50 dry in each airbox.

There was drone when throttle was applied at highway speeds in 6th, I didn't find it unbearable, its all personal preference

I had a discussion about this, i think one of the hang ups was the amount of money it cost to effectively tune the bosch ecu.. or something along those lines especially for fuel management and what not

[z06psi]

N2O is the way to go. Dry shot before the MAFs and it will adjust on its own. To a limit though. But 100 h.p would go a long way in this car though.

[BlackS6]

100 Hp would do wonders in this car.. if we could all contribute equally that own them then i think we could come up with something that is feasible and affordable..other than a 20k turbo kit

There's actually nothing to be done. The major restriction in the S6 is in the intake manifold. If you bossed the hood then you could fit a gallardo intake manifold (can be purchased for cheap actually) on there and the car would be almost instantly a monster (after tuning and all the other adaptations) but that will easily cost you a boatload and you have to sacrifice the hood. In theory the IMF could be modified like they do to the RS4 IMF but nobody is offering that service and last I check JHM wouldn't do it.
