2002 S4 Revised Turbos?

[Jamxx]

Hey guys.

Looking at trading for a 2002 S4 with 131k miles. Still on stock turbos. I was told that the turbos were revised for this model year, but I do not want to have to get myself in a situation where they would need to be replaced anytime soon. What is the likelihood that they would be in good condition? Or any other information I should know about the car to look for/ask about.

Thanks!

Nope, same turbos as the 2000, 2001, and 2001.5

131k, is it chipped? I pulled turbos out of a car that had 185k on it and they were perfectly fine.

Hm. Yes, it's GIAC Stage 2+.

Hm. Yes, it's GIAC Stage 2+.

So its a Giac X tune most likely. Those are one of the most aggressive tunes you can get...if the car was chipped for a long time, beat on etc...wouldn't expect the turbos to last a long time, but sometimes people cant get the K03's to blow no matter what.

Apparently it spikes to 17 and holds around 14-15 psi, if that helps you identify the tune. It is also an older tune, I believe. The current owner does not know when the car was chipped, unfortunately.

Giac regular probably

The original poster was incorrect. The turbos have been revised from MY 2000 to 2001.5+:

I believe the revision was to the oil lines into the journal bearing.

The turbos are not any diffrent at all

The ol' myth.

Why do you say it's a myth? Borg Warner updated their S4 K03 part numbers and most people on audiworld claim different. Why would Borg Warner update their part numbers if there wasn't a change. Maybe the change wasn't significant but the part was updated in later model cars.

Well, I suppose I've asked an old question then, haha. I suppose I'll just keep a rainy day fund and throw K04's in there if I have to. Any other tidbits of information?

Sure, Plenty..

To settle the score:

There is zero difference in the turbos and the oil lines. They are all the sames. Its a myth propograted by random people who want to feel special they have an 02 or 01.5 car lol.

Where is this information coming from? You can't just say something without any data to back it up. Additionally, what's your justification for Borg Warner changing their S4 K03 part numbers from ending in H to S if the turbos are identical? It sounds like you're the one spreading the myths.

Regarding your last comment - Are you suggesting that the 00 and 01.5+ S4s, as a whole, are the same? I seriously hope not.

One last thing, its propagated.......

Rob, I don't think PZP is suggesting there is no difference in the 00 to 01.5 B5 car models. He is refering to the turbos--which is the original poster's question. I've been to his shop. He regularly tears apart and rebuilds 2.7t and has extensive knowledge of the B5 S4. Apart from a physical examination, and the specs which PZP has, I am not sure how you would expect someone to prove the turbos are unchanged. Maybe a notarized letter from the head of Borg Warner? The fact that the part number suffix is different, does not mean that the part is "new and improved". But I guess you are free to believe whatever you want. Also, feel free to correct any of my grammatical mistakes if it makes you feel superior.

[pzp107]

Ok heres my proof.

I build motors from people of all types from stock to 3L strokers etc. We are talking 1.8t and 2.7T;s here. I have parted 25 b5 s4's now, 26 in about a week. There is no one out there that has parted A. as many as me, and B. strips them down to bare chassis as well as builds them for other people.

You can take what I say about this issue to the bank. Do not kid yourself. There is zero difference.

sorry I just noticed nfx has made my point for me lol, sorry and thanks.

Yes I was stating the turbo and oil line differences or lack thereof. There are clear differences from the model years. Here I will break them down for you.

early vin split got aluminum front uprights with bolt in wheel bearings and 1 differing control arm vs steel uprights with press in wheel bearings
early vs late style badging on the hood grill, cluster, and trunk,
square style intake manifold and f hose based PCV system vs spider bodied intake manifold and revised PCV system
ESP vs no esp
differing ECU box letter codes - all hardware interchangeable
differing sport package rear seat alcantara striping (some full lower seat, some not)
steering wheel badging
pink vs yellowish injectors
valley pan breather cover variation with wall inside vs no wall
abs modules change throughout the years
-gas tank vent line in different locations based on PCV system and manifold design
-2 different battery hold styles or brackets ( i know its stupid but its a difference)
PS covers are different between early and late because of the differing core support wiring harness plastic wall for clipping the connectors on and the ABS system brackets differeing
early vs late style large triangular cover (raised vs flat) audi rings
phone vs non-phone style front door card and speaker
esp button vs non-esp button on dash
screw on without tethered vs tethered gas cap
shift linkage/ shifter differences
fuel rail differences

01 s4 - early style looks and has features of 00 - there is some overlap so their are frankenstein motors out there so its not so easy to tell between 01 and 01.5

Common myths - there is no updated collars or syncros in any of the 00-02 s4's 01E trannies
-there are no upgraded turbos or lines
- non-fhose pcv system is not better then the updated pcv system ; the routing is just different thats all
-there is no difference between manual and auto cranks or whole motors for that matter. Only difference is egr and secondary air system which are unbolt and tap in machinist ball and you have a manual s4 motor
-engine harness is reusable from auto to manual and vice versa. You will have extra plugs on the auto left over but you can use it without problem
-heads are not side specific. They are the same side to side. Just put the coolant plug on the correct side and you can built them either way

and FYI I think you should be on a forum longer then 10 days lol before calling me out
