It is interesting information but it's wrong.... Where did you get it from?

As examples:

Final drive ratio it states as 3.20:1 when in ETKA the rear Diff ratio and Gearbox Pinion Gear is 4.11:1

Also there is no difference between the following Block&bottom end, Cylinder Heads and head gasket based on ETKA all the parts are exactly the same, hence how can the compression ratios be different?

I would be surprised if there are not just a few minor changes to trims and drilled rotors std as well as an ECU remap to get the additional ~31kw in power.

Yeah that's a load of crap.

The big differences:

More HP due to a retune
Wheels
Interior had a few more options like funkadelic leather.
RNS-E versus NAV plus
Punched brake rotors

[p3u]

Only performance differences are different ecu map, and comes standard with the additional oil coolers behind the intercoolers, which are on all US spec RS6's. Drilled rotors are standard ( as they are in the US) and SE exhaust standard as well.

Also there was an optional sport suspension kit which lowered the car 10mm.

[wayred4.2]

+1 to Scott

[milka]

Yeah, but I think that unless the US spec ones are different from the Aus spec ones then they are not oil coolers behind the intercoolers but are actually additional radiators.....

[p3u]

thats what i meant, thanks for catching that.

[milka]

Scotty, are you saying my post is a load of crap? Because you pretty much just agreed with what I posted? Or are you just agreeing with my post?

are you on rs6.com btw? Havent seen your user name before

[milka]

only recently started here and rs6.com. Have been on Audiworld for about 7 years, had a Stage 3+ B5 S4, fully home built with everything done by myself at a friend's workshop, and home brew fueling with Lemmiwinks

Currently building up the RS6 has curretly got:
Milltek Downpipes and exhaust
KWv3s
Hotchkis Sways
N249 delete
SAI delete
Profec B running boost
Upgraded incooler cores (now 4.5' bar and plate cores in std end tanks)
Giac tranny chip and Cust Engine Chip Lemmiwinked!
Last run it did 327kw at all 4 same day an APR modded RS6 with Remus exhaust did 257kw ;-)


Next stage is (half of engine build is already done, mainly need tuning! or go standalone):
Pauter rods
Full head build (with supertech oversized SS one piece valves, Ti retainers)
JE Pistons
ACL Bearings
ARP Head Studs
2*GT3071R /w Tial exh housings
2*38mm MV-s wastegates
B7 RS4 gearbox
Clutch Masters FX850 clutch

So much to do and so little time, wish work was a bit slower!!!

[p3u]

You seriously need to post some pictures. :)

Heres what I got.

Milltek Resonated Exhaust
Piggy pipes
Tozo Transmission
Dynamics Torque Converter
MTM TCU,
Eurocharged tune
JHM 2 Piece Slotted Rotors
Hawk HPS Pads
Hyperboost DV's

What does the N249 delete and sai do for you?

[milka]

Yeah will definately post some pics, might even put a build thread up here.

Oh also forgot have done Hyper boost DVs, Stasis Alcon 370mm brakes and really nice custom catch can too, will post some pics when I get a chance,

Oh, 249 controls the DVs so the ECU can't open them. SAI is secondary air injection, just another thing that can go wrong, can be expensive to fix and takes up room I need for other things, mainly the external wastegates ;-)

Oh, my original build thread is here, but I have not updated in a while, as I got married and have had very little time to play...

[p3u]

Can you give more detail to the n249 delete and whats involved. Any drawback?
