The nice thing about using the awd rear end is it gives you an apropriate suspension setup and rear subfram setup for a diff and rear drive.
If it was me, i would be doing the awd rear end swap but ditching the shitty weak stock diff in favor for a differential with some balls out of an awd car, like and evo for example, some custom fab to mount it where the stock volvo diff sat and some custom axle shafts and you would have a fully stock original rear suspension setup with a beefy drivetrain.
Dont bother using the the stock transver engine configeration, if your going for rwd just cut up the firway and exhaust tunnel for a transmission and mount the motor the proper direction.

The biggest pain in the ass i can see would be modifying the body to fit a transmission inline behind the motor. but if your planning on using that s6 aan 5cyl audi motor this is the issues you will be dealing with anyways.

Yes, Idk who said it but the idea of swapping the crappy VC from the AWD for an open center diff and rear LSD was stated before, would be what i would do if i tackled a project this big. then i could retain a constant AWD system, the only significant loss you get from this is that your car is gonna run outta punch in the higher speeds, but if maciek keeps his current motor that shouldnt be a problem

Now lets just say maciek wanted just RWD. Could a 700 or 900 series rear subframe setup be used?

There's no point when the IRS AWD will properly align with the 850/v70 body. The rear LSD diff is the same unit used for RWD applications! If you're mounting the motor fore/aft, then there are no BG issues, you just eliminate the DS/VC setup & make a straight driveshaft to replace it.

:Facepalm:

I completely forgot about the rear AWD subframe.............That would be the real deal for a RWD setup, just one question...how strong are the rear AWD axles?

[maciekb2002]

I will say the rear axels are 75% thickness as front .
I found today 99 m3 gear box , I am still thinking about set up !!!

Is the spline count the same in the rear as the fronts? In other words would the front axles mount to the rear hubs? I have a dream project for which I need this info

M3 gearboxes are some nice shifting boxes.

Adapt the rear axles from a 960/760 RWD IRS, since the diff is the same...

I don't want to take this off topic but think rear mounted white block with fwd trans using rear hubs. Like I said dream project using my spare engine and trans.

Would be killer.

I was hoping they were stronger lol

i also have a dream project thats why i asked (its a very distant dream)

i know you keep talking bout inline 5's, but just a thought if u can get ur hands on one within ur budget, but what about the v8 from the xc90?? i mean look what noble did with it ya its an rr setup with porsche trans, but still, im sure you could find a suitable trans for the job...

Hey, it would end up mid engine, like my X1/9

my "eventually to do" list includes a rear engine sand rail with a 5cyl whiteblock and m56 with a big ass turbo =]

anyways /thread jack

maciek any news?

[maciekb2002]

I went shopping today to scrap yard.
Picked up 130 lbs of square tubing for rear subframe set up.
540 rear end is going in. Hoping this weekend but I am not sure If weather permits.
BTW I work for with guy who buys and sells all kinds of volvo stuff .
I can get my hands on as we speak . 2.4 lpt 2002 s60 engine , s80 turbo engine 2001 , 16v block non turbo yet 1992 . and all bunch of 5 cyl from 90's
S80 turbo engine Is one of the favorites ideas .
Now question. I was wondering if ARD would be able to tune S80 ECU and dis activate all the immobilizer crap and adapt cluster from S80 .
Using S80 harness.
Any suggestions? Always open for new ideas

You can almost bolt it up. Need to get some brackets form AWD v70 version .
But that rear end set up is just wearied. Plus LSD is a must

Has this been done? I've compared the rear ends of FWD and AWD x70's and it appears the frame lacks the needed holes to do a FWD --> AWD conversion and is completely different between the two. Otherwise, I'd seriously consider converting mine to FWD rear suspension.

In any case, the OP seems to be doing it correctly with the rear end they've chosen.

S80 ECU is ME7 so it should be something ARD can do.

[maciekb2002]

I don't want to go with transverse configuration. Engine stays inline with tranny and drive shaft. I will try to acomplished real rwd set up.

[Jardim]

How are you going to set up the rear suspension to accommodate the changes in drivetrain (FWD to RWD)? are the FWD cars' suspension balanced differently than RWD?

Thank you SO much. Going to the junkyard tomorrow to see if I can strip a FWD rear end.
