**Auda** · 10-14-2010 04:42 PM

Looking for a rs4 engine. Any ideas for where to look?

**AwdOwns** · 10-14-2010 04:45 PM

I might be way off but German Ebay maybe?

**TomyG** · 10-14-2010 04:46 PM

I thought the engine was the same? but with k04s instead of k03s? among other things..

**Auda** · 10-14-2010 04:50 PM

Completeley diffrent internals, and the head is made by cosworth. Much better flow.

All RS4s were indeed built by Quattro GmbH, but not all heads cosworth. Some were more special then others. This is what I've heard of course, friend specifically bought a Cosworth B5 RS4 head stating how hard it was to find over the normal RS4 head.

**Auda** · 10-14-2010 06:33 PM

Tell him to stop bragging. A normal rs4 is enough to brag about. His rs4 are not more special than others. All heads are cosworth. :)

"For the powertrain detail of the B5 RS4, its motive power came from a modified version of the B5 S4's 2.7 litre V6 'biturbo' - a 2,671 cubic centimetres (163.0 cu in), 30 valve (five valves per cylinder) 90° V6 engine (parts code prefix: 078; identification codes: early version: 2000 ASJ, EU2 compliant, and later version: 2000-01 AZR, to EU3 standard). This engine was developed and manufactured in the UK by Cosworth Technology (now known as MAHLE Powertrain), and featured enlarged intake and smaller exhaust ports on the two Aluminum Alloy ALSi7mg cylinder heads, two parallel turbochargers (one per cylinder bank), and larger side-mounted intercoolers (SMICs), together with new larger intake diameter hoses for induction and enlargedexhaust system, and a re-calibrated engine management system. The modifications were enough to increase the engine's power output from the 195 kilowatts (265 PS; 261 bhp) and 400 newton metres (295 ft·lbf) of torque on the S4 - to 280 kilowatts (381 PS; 375 bhp) at 7,000 revolutions per minute (rpm) and 440 newton metres (325 ft·lbf) at 6,000 rpm"

There. Go make a little friendly fun of your friend. :)

OP posted asking where to get an RS4 engine. Semi OT with cosworth discussion.

**Just_dizzle** · 10-14-2010 07:16 PM

the heads were COSCAST/Cosworth

super rare COSCAST RS4 Heads made by Cosworth in England

**Auda** · 10-14-2010 07:25 PM

All RS4 heads are made by Cosworth... If you got other info than i posted up here show me link.

Eurospec does not have those heads. I'm looking for a RS4 enigne used.

Both ASJ and AZR are equipped with Cossie heads. Coscast and cossie is the same thing....

Maybe its rare with rs4 engines in the US, but not in Norway.

rs4 engines in the US?! the cosworth rs4 heads say coscast on them and are not on all rs4 engines

**Scotty@Advanced** · 10-14-2010 07:34 PM

Very little is similar from the RS4 engine to the normal S4 engine, and all of the RS4 stuff is uber expensive and often difficult to locate even in Europe. Save your money and time and build an S4 motor.

As far as the heads go who knows the truth most of it is My brothers roomate slept with a girl who had a facebook friend that walked the dog of the old lady's who's son's ex wife took the same flight and overheard a couple joining the mile high club in the lav of which the guy the that delivered the mail for the cosworth employee who tweeted in a drunken stupor that not all RS4's heads were cosworth but you could bid on real cosworth heads that he put on ebay with a minimum bid of 1,000 pounds and he takes paypal but only delivers to confirmed addresses.

Sorry forget my ramblings, too much beer and I thought you were in the states.

**Auda** · 10-14-2010 07:35 PM

I give up. Look it up on ie: wikipedia.

**Auda** · 10-14-2010 07:37 PM

Funny guy Scotty. Made me grin a little. ;)
Btw, as you may know, the 2.7T in A6 and the 2.7T in the b5 S4 is the same thing. Engine management is the only thing that sets them apart.
So i don't see why i should build on a S4 engine, when i allready have one with the Dahlback chip, milltek exhaus etc.
The RS4 engine only needs rs6 turbos and a chip, and we are looking at close to 500 hp. That, you dont get with the S4 engine...

**Rated S** · 10-14-2010 07:41 PM

ebay.de and ebay.co.uk are probably your best places; though right now there is only a B7 RS4 engine listed on both.

**Auda** · 10-14-2010 07:44 PM

Thanks. ;)

Ha... You really do not know what you are talking about. There are very few cosworth heads that were made using the COSCAST method. You can only verify it by looking on the heads to see if they were stamped. Talk to Adam that is selling his set that he sourced. He knows all about this and he has a set for sale in the classifieds. Trust me if it hard to find a set and it will cost you to get an RS4 engine.

It is not worth it IMHO. Adam has the flow maps showing the 2.8L heads flow more than S4 and RS4 heads. If you build an S4 motor with 2.8L heads and all RS4 intake you can easily break 500HP with RS6 turbos. It has been done many times by VAST tunes even without the 2.8L heads.

Good luck with the hunt and personally I would stick with 2.8L heads and build an S4 motor. That is what I did for my TiAL car.

Last bonafide RS4 engine I saw was being offered @ 8,000 euro. 8,000 EUR is like 200 billion in our wonderful US dollar which can buy a whole lot of parts for the 2.7tt S4 engine including a couple huge ass turbos.

It is easy to say that $10k which 8000EU translates into if not more, can buy you a built S4 engine that will outdo RS4 is every aspect including it being 3.0L while at it.

RS4 is not really that great given $$$$ it costs. Now, if they were as abundant as used S4 engines... it would be no brainer to go with Rs4.

**Auda** · 10-15-2010 12:46 PM

I have found two rs4 engines for about 5.000$. And yeah. Got mail from the main importer here i Norway. All RS4 had cosworth heads...

I don't know how many times people have to tell you but NOT ALL RS4s CAME WITH COSCAST HEADS.... trust me I looked into it and it is the fact. I would bother posting up the stuff online that shows this but it is a waste of time because anyone can google search nowadays. It is also just not worth the money.

**Auda** · 10-15-2010 02:20 PM

I never said Coscast. That's probably some sort of special production thing. But ALL ARE MADE BY COSWORTH. And it says so on numerous sites. Including wikipedia. So lay off the caps, and take a besservisser pill. ;)

LOL... The better heads are the COSCAST heads where they use a special casting process that was developed by Cosworth to make the heads. COSCAST RS4 Heads made by Cosworth in England and as far as all the other RS4 heads too but using a different process. Next time you need to clarify your question.

You keep giving wikipedia as a resource, but you are aware that anyone can enter whatever information on there as they see fit. It's NOT verified info, it's just whatever some guy THOUGHT is to be correct.

Don't get me wrong it's a good resource, but it's not to be used as a solid reference
