AWD Swap almost DONE

[O2VW1.8T]

Well today i installed the whole rear of a quattro B6 A4 into my 2004 audi A4 front trak. Gas tank fit perfectly, all the straps fit, stock speed sensors fit, stock e-brake cables fit. I had to extend the fuel pump harness to go under the seat as the FWD fuel pump is in the trunk. So all i did was fallow the harness and re-ran the harness to go under the seat. No cutting at all... Thats basically it... I found out the quattro shocks are the same as the FWD sport, only difference is the springs at one more dot im guessing a little stiffer cause of the weight. anyways heres the pics.

[Audi Skate Snow]

[J-jizzle]

[J-jizzle]

[O2VW1.8T]

Depending where you buy. I paid 550 for the whole rear end, 125 for gas tank, 125 for the fuel pump cause the junk yard broke the fitting on it.. I still need the trans and driveshaft and im done. But im going to try something with the stock trans..
Got this stuff from the junk yard

Any idea how much the whole rear subframe weighs?

[O2VW1.8T]

Any idea how much the whole rear subframe weighs?

I would say maybe 2 times as heavy as the FWD one. I can lift the FWD one with 1 hand, its probably 80lbs. I would say close to 200 maybe less.

Excellent - glad its coming together for u hope all the sensors go into the ECU just fine u might need to do a lot of reprogramming... wonder how that part will work???

It all works, the only sensors are the rear speed sensors on the axles. ESP still works.

[Dopefish]

I almost gave up on this possibility, although I had still been saving just in case I came across the parts to give it a shot. THANK YOU for proving it is possible!!!

[AudiA4_20T]

youve started a trend peter, this is the new cool thing to do lol, anyway Im headed to the junkyard in a few for the extra trans

[CTS Turbo]

Looks good Peter

What sensors? What ECU? Its Quattro. Its mechanical.

You just have the rear speed sensors for ESP and ABS as well as the roll control sensors (on the anti-roll bar).

[O2VW1.8T]

Ok well i tried to install the back half of the quattro trans and it wont work. I will need a trans

quatto rear tail section, you can see the splines to the center diff


FWD section

[downhillracer]

wow, nice job! to bad the trans conversion didn't work

[Papachristou]

you just gave me hope, how much did that set you back???

Is it necessary to repost all his pictures?

He said he got the stuff from a junkyard

[walkerkd]

awesome job man! only 1 question looking at the tranny tail section. do you by any chance have a side by side cut sheet to the tail sections of the tranny.. reason im asking is could there only be a spline connection or is that a differnce in the tranny. maybe you can locate the diffence without having to completely replace or swap them. i couldnt find anything but maybe someone has a tranny rebuild manual.

Does Clint have a trans coming to you?

[viziers]

Hmmm this is giving me ideas..... I wonder if one can do this in a B7 A4? Is the body the same in regards to a B7 AWD body to a B7 FWD body Is the Q system the same? Mechanical?

I know this is the B6 A4 forum but i just had to ask. Sorry for the brief thread jack.

Please Pm me to keep it out of the OP's thread or if he wishes to keep it as more info for others like me or him if he wants to swap a B7 A4 as well.....

I can go through the individual parts tonight, most likely the only difference is the main shaft, however I would venture to say that buying one and installing it will cost more than a junkyard tranny.
