E30 M3 S62 Build - Loads of queries about 4x4 drivtrains

[thatphysicsguy]

Yeah from further digging, it looks like they used the drivetrain similar to the escort xtrac, a competing rally car.

Have no clue what motor they used or anything else. It seems to exist almost as a footnote in the history of group b and rally cross.

I was under the impression it was a turbo S14, but I don't know where I got that from.

Any updates on this build, Adem?

[Turk]

None at all Frank, Been swamped so this is on the back burner atm. Soon though, soon..

[DER E30]

Updates??? THis is a really cool project that needs to be out terrorizing quattro Audis and such.

On the note of bump steer, I wouldn't freak out about moving the rack a small amount. Fit the part where it fits.

Does somebody not make a bump steer adjustable rod end, something like what I'm running on my truck with C5 corvette suspension? I narrowed the front end of my truck 6 inches and just got a narrower rack (flaming river xl) and those adjusters in the pic... I pulled the spring off the coilover and went through the range of motion with a jack under the hub, and played with the shims until the toe didn't change any noticeable amount.

My truck drives fine and doesn't do anything super weird in the bumps. I built the frame completely from scratch and didn't do any CAD modeling or any of that ...

That would work, @$$uming the taper is correct. Of course if it isn't, a tapered reamer would fix that.

Cool... I wonder if those would work on an iX.

The E53 front diff uses a "wide" carrier that shares dimensions with the 4 cylinder Z3 unit. The Quaife for the Z3 4 cylinder works in the X5 front diff. However, if you're going to do that, you'll need to disassemble the Quaife and turn the gears around, because in the front end application, the torque is in the opposite direction from the rear end application.

Hey guys, new to the forum.
I'm thinking about using the X5 sump and diff in a mid engine aplication. I would change the rotation of the t-case so the driveshaft spins the diff like it was going REALY fast in reverse. Can this damage the diff? The diff is just about the only part of a car I never needed to pull apart so I have no clue as to what would happen to a diff going backwords in 120mph.

How hard would it be to turn the gears around in a quife diff?

Hey guys, was surfing the 'net and somehow wound up on this thread. Felt compelled to register and post, as I'm tearing through the 4.6iS (again).

Don't know if I can help, or not... or whatever, but give me a shout if you need a measurement, a picture, or something. I'll do the best I can to accommodate.

Cheers. Good luck.

Interesting... Do you know if the 4.6 pan and sump bolts on to the M60 engine? Will I have to/is it possible to take the oilpump from the 4.6 and fit it to the m60?
I know a guy who is chopping one up and I think I'll get the parts dirt cheap.

Are you going to be turning the engine around "Lambo style" so the pulleys are at the back and the transmission is in front?
The front diff probably isn't very strong. The 168mm diff is only good for ~250 HP in a RWD application.

I haven't done the Quaife reversal, but if you're going to turn it "backwards" you won't have to.

The M62B46 from the E53 X5 4.6is and the M60B44 from E53 4.4i's, E39 540i's, etc. are very close to the same engine.

The N62 is quite a different machine.

DAMN! I was hoping to make it look factory built but if the diff is that weak I should consider placing it past the front of the engine... I need to find a X5 forum to get more info on the front diff and what might swap into it.
Yes, It's lambo style I'm going for. Lambo has a threeway with ariel atom and a lotus seven, their offspring would look like the car I vision building.

By the way, awesome build this E30, hope you get it on the road soon. I have a stripped and gutted E30 with full rollcage but seeing what awesomeness is beeing created in your garage, I can't half-ass a build with a mere 4.0:)
Alltho a mid engine E30 would be somethin' else... hmm...

The front diff bolts to the side of the oil pan... nothing but an e53 front diff bolts on there.

You'll need at least a 188mm diff and at least 94mm CV joints.

Yes, the oilpan and pump from M62 styled X5 engines (4.4 M62 and 4.6M62) will bolt straight onto the M60 or S62 for that matter. The oilpump sprocket will infact line up nicely with the crank sprocket, and it will all work well.

N62 from the 4.4 4.8 versions of N62 will not bolt up nicely to the M60 or S62. Ask me how I know.

(JK, I've bought a pump and pan from M62 X5 I can not use, its for resale now, and I've also bought N62 parts and they are not easy to make work either. My application is E36 however, so I'm just gawking in from the outside in admiration, and adding info when I can)

Alex.

Maybe I should just go ahead with the M60 awd superseven that I planned in the beginning.
Did anyone figure out how to get the transfer case electronics to work w/o the e34 abs and whatnot? Guess if one could just figure out the currency(?) the T-case needs to lock upp it would be an easy fix...
I spoke to a retired rallylegend about e34 transfer cases. According to him bmw made a few cases where the discs were replaced by some sort of metal flakes that solidify when you zap them. A bulletproof setup that in the end was too expensive so the production was stopped. Anybody know more about this?
