Q1: how is secondary fan activated upon ac operation? if i understand properly the b6 fan control module takes care of this, which is controlled by b6 a4 ECU, so i am wondering is there a trigger wire output by HVAC i can relay for the secondary fan?

Q2: is anyone in full obd2 readiness yet (if i understand right that's only thing needed to pass our emissions here)

Great question, I see the wheels are turning. I thought about this as well, and decided that the B5 module would be a waste of money since there is only 1 fan on it. Might as well get a standalone unit and control both fans instead of wiring up a new fan harness and a secondary relay. Anyways you could probably tap the AC compressor wire to trigger the relay. Not sure if there is a direct wire to the ECU on the B6 to tell it that the A/C went on or if it does it through CAN.


I'm also interested if you can pass readiness with this swap.

Why wouldn't you? When they plug in OBD2 it just checks your 2.7T ECU. if the ECU says everything is good then you should be good. there is no VIN stored in the 2.7T AFAIK

[stringerb3ll]

the b6 a4 compressor uses PWM, so i would have to make a PWM trigger? or is there another electrical tap point?


:Clint i called you, give me a ring back if you can.

my father suggested running the aux fan off an AC pressure switch to a relay.... thoughts?

[RKLamb]

I have a stand alone switch for the fans now just wondering has anyone else gone this route to run both fans and if so what do I need to do to run with second fan for AC.

[stringerb3ll]

i was thinking on just using a cheap universal thermo switch for primary fan, and finding a relay or transistor-relay connected to AC pressure switch for secondary. like

http://www.summitracing.com/parts/der-16749

this also looks nice a powerful controller but pricey, it looks like it has some sort of ac trigger input or something.

[nefkntym]

I am using a "Hayden Automotive 3647 Adjustable Thermostatic Fan Control" for my fans. I have two aftermarket SPAL fans though. You can get that controller for ~$35 from Autozone, Summit and Amazon. I picked it up at Autozone and it has been working great for about a year now.

[stringerb3ll]

what 2 wires/pins from B6 body plug are responsible for running a 3.0 PWM AC compressor?

i have read something about T17d pin 5 RED , and if i understand right, it was instructing to add a line from AC compressor to engine harness ground, and i assume the other wire to T17D pin 5?

[gliultrasport]

how long does this swap take to do?

[stelvio]

From the threads I've read I understand the mechanical swap is not much of a hassle if you have all the parts, but the wiring is more of a pain. If you have everything including wiring harnesses I understand 2-3 you should be good [with prior experience]...?

As of this evening I am now running the two stock 3.0L fans and my smaller SPAL pusher fan on the AC condenser. I have the main fan (driver's side) wired in like a B5 S4 EFK and the the other two auxillary fans are using a B5 S4 fan controller for control like stock. Working good so far.

[stringerb3ll]

i dont have a b5 s4 fan control module, what exactly is "like stock" is the b5 s4 module activate the secondary fan for ac function? is so where does the module get the "AC ON" signal?

2.7t engine is pretty much the 3.0 V6 with turbo's on it so use the 3.0 weight + turbo's + intercoolers if you wanna get pedantic. I'm curious though, why would you like to know?

[LINDW4LL]

2.7T is around ~430lbs.

1.8T is 290-300lbs

So about 130lbs.

Except the 3.0 is aluminum and the 2.7t is iron. So cant really calculate it that way.

question regarding B6 A4 plug white plug pin 10 Blue/Green, this is the power steering wire which the b5 doesnt have. from my understanding this controls a PWM valvei n power steering rack which makes steering easier at low speeds. i was wondering if anyone with a running b6 could put an oscilloscope on this wire and figure out what type of signal the b6 engine harness sends into the body plug, it would be nice if it was just a VSS signal

[stringerb3ll]

i have a general question about ESP according to this thread and supported by http://s4wiki.com/wiki/M-Box#M-Box any 2000-2002 manual ECU is mbox flashable, but i have been reading of more then a few people with A boxes re flashed to Mbox having ESP and or ABS issues (in 2001.5 s4's, as 2000 s4s don't have ESP right?) I also read these steps may also be necessary for some people

http://s4wiki.com/wiki/Cluster_recode
http://s4wiki.com/wiki/Engine_recode

i think the more details of what each person encountered would help the overall, did anyone do a cluster or engine recode? can anyone confirm that ESP works on a flashed a6 ECU, i myself have a T box from a 02 s4, but it looks like a6 ecus are the cheapest and essayist to find, so this may be relevant for others?

[quattroloco]

I used a 2000 a6 ecu originally sice it was the donor car. I flashed the cluster before the swap but only because it was an auto that I was swapping to 6speed. I had the 5k rev cut and no esp untill I updated to hitachi maf so I could use the 01.5 mbox.

Assuming you used the same year engine also? My biggest thing right now is knowing what to get drivetrain wise since I will also be doing a manual swap while I'm dropping in the 2.7. Do you mind exchanging some messages with me?

That is the easiest part. 6spd swap has been covered many times over in the b6 a4 forum no matter which motor is mated to the transmission. Quattroloco's thread, Vinny.DTW's thread. DrJonez' thread, sleeperavant's thread. etc... granted the last one is a 5spd swap but everything is the same. the trans just has one less gear in it.

my 6spd swap is even easier because I am coming from a 5spd. I only had to buy a b6 s4 trans, shifter linkage, shifter assembly, front driveshafts and center prop shaft. my rear diff is the same ratio as the b6 s4 so I get to keep my rear diff.

[devinfulcher]

Im new here and not sure if im writing in the right spot. Just looking for info and advice. I have a 05 b6 s4 and recently broke something to do with the timing chain. I have spend about 2 weeks reading in this forum. It sounds like the 2.7 swap is the best option, does anyone know of any reputable shops near chicago that could do this, and an approximate cost. I dont think i couldnt handle this project. Any help would be great......thanks

welcome to the good side. You'll probably pay ~$3k+ labor for an engine R&R, plus fitting SMICs, plus wiring, etc. I would find a local guy who wants to do the swap or attempt yourself. Otherwise this is probably not for you. You could do a 1.8T for awhile, will plug right into the S4 and hold you over until you get the 2.7T sorted

[devinfulcher]

I'm guessin not too many people are putting a 1.8 t into the b6 s4....but I guess if it were easy to do it would get the car drivable for cheap until I figure out what I wanna do.....is there a place in this forum with info on putting the 1.8 I in the b6 s4....thanks for the advice....

Thanks for the reply, but yeah I've done my searching and I kept reading that depending on where you're starting from, you will need to get the proper trans plate, and the proper length prop shaft. Just double checking numbers to ensure I am buying all the right pieces. I checked for quattrolocos thread and all he says is he has now installed the linkage and everything so no write up from him. Ill look into vinny's and jonez' thread also. I just need the DIY lol! Thanks again man.

Should be plug and play man. Maybe have to change a few wires

Thanks for your help........if ya ever feel like makin a harness for the 2.7 swap send me a message. Think ill just do a 1.8 till i do more home work... thanks again

[4BiddnA4]

I have 3 harnesses currently... 1.) A 2000 s4 harness + m box ecu 2.) An 04 A6 2.7 auto Harness 3) An 02 1.8T harness (from the car I'm swapping into). The question is which harness is easier to use or mate with another, or can I simply use the A6 harness and swap pinouts accordingly? I have asked this question a few times here and pm'ed different people which seems to be ignored for some reason. I am not asking for handouts or someone to hold my hand in all of this, I'm just looking for what would be the best possible solution.

[quattroloco]

Use the 1.8 harness as your addaptor harness between your cars body harness and you'll mate that to a set of b5/a6 body plugs.
B6 body(your car) plugs into b6engine plugs adapted to B5 body plugs that will plug into b5 engine harness (use the 2000 mbox)

Thanks quattro, appreciate the speedy response. Ok so just use the B5 engine harness and mate it with the B6 body harness plugs which I already understood. I just thought for some reason or read somewhere it would have been easier to use the 04 a6 2.7 harness because it had most of the body plugs, and relays included, and that most of the pinouts were in the correct positions already compared to the older b5 s4 harness. Is this an incorrect assumption?

Possibly... I went the adapter harness route.

This is an incorrect assumption, actually the 00-02 harnesses/ECUs are the best to use due to no immobilizer, no SAI, and generally more abundant tunes

So anyone has any updates on what to do with a B6/B7 AC system as far as wiring go. That is the only thing I have left to figure out.

Use the 3.0 compressor stuff. Either this thread or Clint's thread someone posted up using a 3.0 compressor bracket to attach the B6 compressor (3.0 or 1.8) to the 2.7T block. It sits in the same location in both chassis so in theory the 3.0 lines and everything should work fine.

This thread has put my brain and my balls into overdrive! I have a 3.0 b6 that is almost out and a nice complete 2.7t on its way...

I am confused as to what is different on the b5 trans plate as opposed to the 3.0. The only diagram for bolt size/torque specs that matched up to my 01e said it was for the 2.7.

part # 01e103551c shows compatible for the 3.0l

Is it a spacing thing?

[quattroloco]

There is a half inch thick trans spacer between the 01e and the 2.7

You could use the 3.0 one if it works. It's the same block and same trans, they should be the same

[Kyleinoregon]

Sorry for the confusion I was under the assumption that I already had a plate in the 3.0 but needed a different one for the swap. When I looked they were they were the same part #. Now when I look at the car I can't quite tell if the 3.0 has one already. If they make the part for the 3.0 it should be there right?

And if I do need a spacer that wasn't there before do I need new bolts to fit?

Downpipes are "off the shelf" 034 3" B5 S4 770 downpipes. I don't think they get any bigger than this, I think it is safe to say that when it is set up like this, any B5 S4 downpipe set will work with no modifications.

Yes, depends on what you have. I'm using B6 S4 chassis AND using the B6 S4 0A3 trans, I'm keeping the B6 S4 subframe and transmission cross support. Which means as I've found out, off the shelf B5 3" downpipes don't fit. So I am making my own custom pipes. Also for anyone interested, the B5 trans reverse switch fits in the B6 trans allowing it to be wired up with out cutting as Clint mentioned in his S4 swap.

It was $10 switch so I took the chance on it ;) It also looks like the B6 1.8T Coolant tank is a better fit than keeping the S4 unit.

I've been taking my time on my swap and paying attention to details vs just slapping things in there. But I'm not too far now. Once I get my downpipes built I can get the engine in the car and start making progress putting things together on the car. Kind of took the past 3 months off from working on this since I traded my V8 Treg for a TTS and have been having fun with that. Here you can see my pipes don't fit, so instead of hacking up ar design pipes, I'm going to use them as a guide and make my own then sell the ones I have.

Notice the 605's ;)

[quattroloco]

nice!

[dougyfresh]

Yes, depends on what you have. I'm using B6 S4 chassis AND using the B6 S4 0A3 trans, I'm keeping the B6 S4 subframe and transmission cross support. Which means as I've found out, off the shelf B5 3" downpipes don't fit. So I am making my own custom pipes. Also for anyone interested, the B5 trans reverse switch fits in the B6 trans allowing it to be wired up with out cutting as Clint mentioned in his S4 swap.

To me that is the easiest approach.

Wonder if the 5spd reverse switch will work too?

Quick question... I know I need to pick up a 3.0 fuel return line in order to get this working (I'm starting with a 1.8t), but do I need to get the 3 lines that run from somewhere near the air box assembly in the 2.7t to the fuel rail as well? Or are those part of the 3.0 fuel return line?

Here is a pic of those 3 lines in question: http://i1219.photobucket.com/albums/dd436/golferguy17/null_zps904a577f.jpg

[stringerb3ll]

two are fuel lines one is a evap, look to page 20 http://www.ibiblio.org/tkan/audi/2.7Biturbo-SelfStudy.pdf the 3rd line is for " solenoid valve for activated charcoal" which comes out of passeger side inside fender, it is a hardline with a rubber hose coupling (it on the b6 1.8t at leased) two lines also come out by the power steering reservoir with plastic couplings, one line goes about 30" to the inside driver fender into chamber one (isolated from chamber 2). Line 2 goes the same 30" of harline or so into "chamber 2" of the reservoir it also meets a check valve and a T fitting and a line runs down the driver side frame rail and goes into the LDP.

[AudiA4_20T]

turns out not only the "bracket" that you need is the same as the 2.7T, but also the 3.0 hoses do *NOT* fit without messing with the charge pipe a good amount.

Still don't have it figured out, working on it today or tomorrow

[gottaBdope]

Well, as promised, I wouldn't post here again till I was ready...and now that time has come. I got lucky enough to find me a local b5s4 that was totaled and mostly parted out. All that remains is the full drivetrain (all four axles, driveshaft, rear diff, 01e) and of course the 2.7t all with only 115k. Just looked at it last night and I'm scheduled to pick it up this coming weekend, but I'm not gonna say the price until I get it (don't wanna jinx myself). I assure you it's jaw dropping though.

So now I'm in preparation stage. I'll have access to the parts I need to get separate from what comes from the car, I'll do the harness matchup myself, and I have a question about the ecu. PO said he could throw I his a box in, but it's got stg2 apr on it and the motor was reverted back to stock. If I make the motor stg2 to support the apr program, will I have any problems throwing the setup in like that?

You wont be able to use the rear diff or the drive shaft. Probably no for the rear axles as well. The engine, tranny, harness definitely. I think you have to do something funky with the front axles if you are not using the B6 01E and axles, that would be a question for Quattroloco.

You are going to need a B6 3.0L 01E driveshaft and a ETQ 4:11 rear end from a B6 or C5.

Dang, I thought I would need the matching rear diff...guess I understood that wrong. Think I'd be okay going a custom route with the driveshaft? Might be cheaper than buying one since we got hookups at a couple machine shops. I guess I'll read through quattro's build thread again...it's been a while. Thanks for your help man.

[quattroloco]

Someone say my name... lol.

You will need b6 3.0 01E front axles but you can use the existing flanges on the B5 01E if you remove the inner covers off the cv axles. Use the B5 axle to flange gasket instead. You'll see when you get there. The pattern and everything is the same its just that B6 axles have a sealed inboard joint and B5 used a gasket. The B6 cover pops right off and the gasket will provide the same purpose. Eliminates buying B6 01E output flanges for the B5 01E.

You can't modify audi drivelines easily... they use kinda a ball socket vs a u joint so most driveline shops can't modify and balance them. I bought a grade A used driveline for $150 shipped from carparts.com I think... can't remem the name but its a nationwide used parts search site that lists location, grade and price.

car-parts.com We use them at the shop. Thanks for laying all that out. I started reading through your build thread again and started to compile a list similar to that, but I like this post much better. Still bummed that I have to buy axles, driveshaft, and rear diff...didn't quite count that into the rough budget estimate in my head, haha.

Well... you'll just have more parts to sell in the end so it will cancel out. Good luck man and post some stuff as you go. Also are you manual already? The b5 shifter ect will mount in a b6 with minimal work... ie redrill a couple holes a 1/4 inch over ect.

Correct, right around there. I would be weary of putting used K03s in though unless they are low mileage.

[mikelson]

hey guys, hello everyone. i want to ask some questions about 3.0/2.7 swap. please help.

sorry if it is not correct place to ask this.

my story is simple. i have done the swap, i have audi a4 b6 3.0 (2004) and i put 2,7t (from allroad 2003) into my car. I recoded the ECU to manual transmission and make chip tunning also, but I have a problem. ECO shows error – low fuel, and the car does not run well on the high speed (even on the low speed sometimes). I left the 3.0 fuel pump. Can anyone tell me, the problem is with the fuel pump? I mean, if I change my (3.0) pump into 2,7t fuel pump, will it fix that problem with the fuel and will engine work normal?

[AudiA4_20T]

Correct, right around there. I would be weary of putting used K03s in though unless they are low mileage.

Eh whatever. If they worked before they'd work again. Spending another $3k+ is not preferred for many

Oh I definitely understand. I'm just saying I wouldn't put a high mileage set in. At the very least check to make sure there is no shaft play. Especially if you're going with a semi-aggressive tune

you dont need the 2.7 A/C compressor? why you couldn't make it work? i hope, i shall not have to install 3.0 A/C compressor and can make 2.7 compressor work normal. i mean electrical connection is the same (to my mind) and physically i already did every line and everything. but before it, i need to make something with fuel. :(

My 3.0 fuel pump has been fine...

I ran a 13.5 @ 102mph with shitty stock engine/trans mounts and about 50psi in the tires. Lined up out of the groove trying to get as much wheel spin as possible. Awd is all about the launch for ETs. Traction can bog you. I'm still on K03s running like 22psi for over a year. I daily this car every day and am still in love with the sound, power and reliability. The maintenance hasn't been anything above normal and I think that speaks volumes about what's possible if you are realistic. I would love to throw some 770s in but not when its my daily.

and why there is 3 lines coming on your fuel pump? one is the main supply line for engine, and what are the others for?

The small line in the upper right is the breather line which you have pictured in your diagram. The middle line is the fuel feed line for the engine. The third with the blue AN fitting is the fuel return line I put in. Below is a picture of the OEM fuel feed line and the breather before I installed my b5S4 fuel return line with the AN fitting.

then i guess, i should not collected together the fuel return line from engine to the breather line. how do you think, the problem with low fuel is for this reason?

thank you very much guys for your advice and help.

but still i do not know, what to do. [:(]

[4BiddnA4]

No you shouldn't have touched anything. Put back everything the way it originally was. You do not need to modify the OEM returnless fuel system. All you need to do is add the fuel return line. I routed mine to the main tank because it was the shortest route and didn't require me lengthening it.

ok man. i'll do everything as you told me and let`s see, if it fix my problem. but i am thinking about the one thing. according to your line system, there will be two FPRs (fuel pressure regulators), one on the engine and the other in the fuel filter. the pressure of both of them is 4 bar (as i know), therefore in engine can not be the fuel pressure more than 4 bar, even if engine needs more (the engine regulates the pressure of fuel with its own regulator). will it fix the problem with low fuel? any way, i`ll try.

but, in this case, i think, i do not need the return line at all, do i?

have you tested this system already? i mean its functionality. is it ok?

so, you also think, if i do line like this, everything will be ok? even on high level of engine run?

as i understand, there is no difference between quantity of transporting fuel (litre) from 3.0 fuel pump and from 2.7 fuel pump? because, as i have already said, the pressure i guess, they have the same.
hope, will be so.

Yes my car is running 100%. I do not have any fueling issues or codes. The fuel pressure regulator in the filter maintains pressure within the fuel feed line, and the 2nd fuel pressure regulator maintains pressure within the fuel rail and return line. They are not working against each other if that's what your thinking or adding additional pressure to the fuel system. As quattroloco stated you need a fuel return....no matter what or how much horsepower your running on the 2.7.

[War Machine]

Just so we're clear, 1.8t fuel pump will be efficient yes?

[AudiA4_20T]

Yes. Mikelson has his whole fuel system set up wrong and is therefore having issues

[MrScary512]

I don't recall but in the thread you had posted about the return vs returnless didn't you say you can just put the 3.0 filter in so there isn't 2 FPRs?

[4BiddnA4]

Just so we're clear, 1.8t fuel pump will be efficient yes?

1.8 pump is just fine until you go stage 3 then you will surely outflow this pump. Even the 2.7 pump is not sufficient enough for stage 3.

I have a question about the ECU. It came from an Allroad with auto/tip. Is it any good to me? its already tuned.

Hey guys, i have done everything like you have told me (i mean fuel system). There is no errors yet and the car runs well, but i am testing it yet. It seems, my car is not enough fast as i expect. Maybe there is another problem, i`ll try find and fix it. anyway, Thank you very much guys.

I have a question about the ECU. It came from an Allroad with auto/tip. Is it any good to me? its already tuned.

Anyone?

[gottaBdope]

I don't know for sure man...I know that I have a 01s4 ecu flashed with apr2 and it's supposed to work. So I think the tune will be fine, not sure about the allroad part. Always wondered if the allroad would work.

[matt7127]

I'm working on putting everything together for this swap and was wondering if anyone is running the B6 5 speed quattro trans. I currently have an 02 A4 trans with only 60K on it and was hoping I could use it without to much difficulty. I know I'll need the adapter plate, but do downpipes and everything else fit?

[mikelson]

hello guys, has anyone the diagram how to make work the main fan as independent? i mean, do i need the fan control unit from 3.0? i have already added the one more temperature sensor for the main fan (because the other two controled by 2.7t fan control unit). any advices? any ideas? how did you fix this problem? :(

[MrScary512]

So I am thinking of doing the jumper harness route, would I need my whole 1.8t harness? I now little to nothing on wiring and not even sure if this is the best plan of attack, advice?

[quattroloco]

If your gonna do a jumper harness you'll keep the engine plugs from your harness (they plug into your cars body harness). The 1.8t engine plugs will get attached to 2.7t body plugs that the engine can plug into. 2.7 engine-((2.7 body-1.8 engine))-1.8 body

Ok guys, found the reverse lights issue I was having. The Bentley manual gets confused when mentioning pins on certain plugs.

All you need to do is go B6 Red Pin 15 (Blue/red stripe) to go to B5 Red Pin 1 ON THE 3 PIN SECTION (Blue/red stripe).

Also, don't get confused with Red/blue stripe. It is definitely light blue with the red stripe

[biglip]

so i got an 02 a4 3.0 6 speed quattro. i was thinking of selling the car but now that ive seen this. i was thinking different lol

Did some wrenching with my buddy

Ok, so I have a few questions;

1: I got a clear look at the vacuum system in this thing, I will be deleting all EVAP items off the engine, and having my tuner remove it from the ECU. This is the valve system I'm reffering too. It won't be detrimental to my system providing its removed/plugged properly, and removed from the ECU for Etesting purposes yes? Serves no other purpose but for Emissions?

http://i1273.photobucket.com/albums/y407/KraftwerkTurbo/2002%20Allroad%20Engine%20Swap/ACFActiveCharcoalSystemAllroad_zps649c41ff.jpg

2: The N75 Valve, It "T"s into the Crankcase vent system, I managed to break a bunch of that damn spider system lol Can I use standard hose to rebuild that system? And why does it run into the PCV system? the 20v's do not

[AudiA4_20T]

Yeah. Honestly no point to get rid of EVAP on the 2.7T though. You're not saving space like on the 1.8T

[War Machine]

[mikelson]

i have made an experiment, i conected the FAN CONTROL UNIT (FCU) as it shoul be (to my mind). 61 connector on the unit is - terminal 61 (alternator), WP connector is - positive supply (from FCU) to continued coolant circulation pump, E1, E2, E3 and E4 connectors are - ground (earth) supply from sensors. i simulated the standart work situation for FCU - i connected the fans, supply from battery, supply from alternator and tryed switch fans useing ground from battery as a signal from sensors to E1, E2, E3 and E4 connectors (2 of them should be the fan switch), but the fans still not work. and there is no positive supply from connector WP (to switch continued coolant circulation pump). i have two FCUs, but the other one not works as well. can anyone tell me, what i am doing wrong? it should work to my mind. how else i can make it work? is it everything wrong? i am sure, everything works on allroad exactly so, as i connected it on mine, but still no result. do you have any idea? how did you guys make FSC work on your cars?

[AudiA4_20T]

honestly you're probably better off just getting some relays

[War Machine]

Just so I'm not caught off guard, I don't need to touch the interior for the swap correct? No pulling dash to get certain wires/relays?

[quattroloco]

Not really. I removed the trim cover under the drivers side dash. The wires and relays will go through the hole under the ecu and there's a few grounds to hook up and secure a relay or two under there.

The response would have been that they didn't make US-spec cars. And the Eurospec ones were something like $115k, after conversion from the 85k Euro price.

I'd have to make some changes but it's applicable. You just have to convert the fuel system to a normal FP. You could probably just snag a 1.8T basket and unplug the FSI stuff. I have a friend who did the swap on a B7. Regardless, I can make harnesses.

For the b7 would i want to source any 3.2 parts or just stick to 2.7 and 3.0?

3.2 front clip

[RKLamb]

Ok I am going to try these downpipes this week. I have tried some without the extension and my vband hits against the tranny brace not allowing them to flex and connect with original exhaust systems. These here were design to fit an A6 or S4 and seem to be longer with more arch, that should help with getting past the crossmember of the tranny. Should be able to modify a liittle easier than my other set.http://i859.photobucket.com/albums/ab158/RKLamb/_3_zps0bbf3963.jpg (http://s859.photobucket.com/user/RKLamb/media/_3_zps0bbf3963.jpg.html)

Think this would be a suitable donor? It's somewhat local (45 min drive for me) Been searching for totaled/salvage title '00-'02 S4's but seems all the decent ones I find are too far away & would be an extra ~$800 to have the car shipped to me. Also having terrible luck finding just a COMPLETE motor; Been searching eBay, Craigslist, salvage yards etc and there is always something major missing..

Kinda sucks that it is a automatic (I'd still need to find a manual ECU right?), but it seems to be the most reasonable one that I've found yet (only been searching for ~2 weeks now though) And the "Needs engine valve repaired" is a red flag but I'm a 1.8 guy and don't know how expensive/pain in the ass valve work would be on a 2.7

I'd stay away from that car, esp since its the engine you want, for the owner to let it get to "Needs valve work" red flags his driving habbits/maintenance routine.

Ahhh yes, completely missed the picture with the hood open....

[Four-Play]

How could you tell that's a 2.7T? Did you talk to the seller already?

In the 3rd (middle) pic, you can see the y-pipe. Yeah the ad is tremendously vague. I'm hoping the low price is due to the body/interior being beat all to hell, with a minor engine issue.. Haven't contacted them yet so there might be a lot more wrong with the car. Keeping my fingers crossed though.

[RKLamb]

So rather than chopping up another set of exhaust pipes in case my new ones do not work out, does anyone make a replacement transmission brace for B6 6 Speed. The brace is just to thick. If I could eliminate that or get a thinner one I would be set. If my new pipes fit I may have an extra set of downpipes for someone dirt cheap.

Yea that's the one. JHM and AWE both make a similar piece. I thought the only issue was the rubber piece that mounts to the trans needs to be taller.
Again, I may be completely wrong.

[207carney]

Trying not to count my chickens too early but I think I may have secured an A6 for a donor car! Looking forward to getting my hands on this and getting started. Setting Dustoff 2015 as my goal to having the swap done.

[RKLamb]

I have a set of DPs that originally had no flex. So I had flex added to them. One side is a olive clamp and the other is a vband. I never welded V bands to the passenger side. If you have a B5 you could get them to fit easily, but if you have a B6 like me you will need to do more fabbing or if that DTS fits it would work out perfect. Already measured to fit a B6 exhaust. I will send you a picture once I get them off this weekend.

[65vetteC6]

Yea that's the one. JHM and AWE both make a similar piece. I thought the only issue was the rubber piece that mounts to the trans needs to be taller.
Again, I may be completely wrong.

Iirc they are slightly different, I asked a member here who did the swap and used the awe one and he said it wasn't perfect. I don't remember if it was temporary or not.

[RKLamb]

If I could bolt up the two big bolts and just one of the small ones on each side that would be great. Now if the whole thing bolts up and all that is needed afterwards is to adjust the height on the rubber I could live with that. My friends cut up his braced and welded some bars to it. Looks like this but totally junkyard rigged.

Clint by any chance could you re upload these images?

clint, can you confirm that the 3.0 fuel cap (in trunk) fits with the 1.8t tank? the 3.0 has the return nob yes?

You shouldn't need to touch the caps. The return line is on the drivers side

[MrScary512]

Point of clarification: are people running SSAC down pipes with the factory horns, obviously with modification?

Another harness for a happy customer

Do you have a documented diagram/wiring map yet? I was willing to pay you before, but you never had any documentation. I'd prefer to do the wiring my self to be responsible for all the connections. I'd buy the info to save my self some time.

Two.

Don't really have time to do plans. I'll do harnesses though

[mikelson]

Can someone tell me, how connect the A/C pump? I have decided to do this so, is it right way to make it work?

Anybody. :(

I used the stock fan switch module on my 4.2 so I can't really help

So the verdict on downpipes. If you have stock B6/B7 A4 6MT trans.

SSAC with flexpipes will work? Or do you need tiptronic subframe?

[AudiA4_20T]

No downpipes "work" with any stock B6 configuration. You COULD use a tip subframe and B5 mounts, or a DTS bar, or (and I think this is the best way) just go to an exhaust shop and mod the DPs

[nefkntym]

I hope you've read up on what is needed to install those DPs

It seems like no one does [facepalm]

Well there is a lot of different information to sort through. While most of it is great info, a lot of it is just idea that were never confirmed to work.



Your earlier post made it sound like with B5 trans mounts and 1.8T/2.0T subframe, off the shelf DPs will work fine. But can you use the B5 mounts with the 02X B7 trans?


Downpipes are "off the shelf" 034 3" B5 S4 770 downpipes. I don't think they get any bigger than this, I think it is safe to say that when it is set up like this, any B5 S4 downpipe set will work with no modifications.

The trans doesn't matter as far bellhousing and mounting goes. The only caveat to that would be if someone wanted to do the swap with a tip trans for some reason. Then you run into the issues that everyone has with all cars that are tip, the downpipes are different because the trans is so portly.

OK. So likely if I have a 2.0T subframe and B5 transmission mounts, OTS DPs will work....

SSAC Downpipes with Flexpipes definitely did not fit on my B7 2.0t swap.
