All parts are in great condition, no moving parts to wear, used for about 2 years or 16K miles. Obviously only fits '95 M3s w/ OBD l. Everything included plus installation instructions. Takes about an hour to install if you've never opened your computer before, less time if you've done it. Jim C., says a '95 M3 dynoed w/ his kit at around 270+ hp, I felt the increase in power immediately. Very noticeable increase in power. I think it's currently selling for around $995, make me a serious offer (please be realistic) and experience the extra power the '95s lacked. Best bolt on for the buck!

Bearing preload and seal drag will cause some stiffness but you should be able to turn it by hand. A viscous limited slip explains the output shaft torque. Gary Derian > No crunch.

It is not a viscous coupling but a hydraulically applied clutch. Hydraulic pressure being generated by tire slippage. I though the first application of a gerotor limited slip was the front axle on Jeeps ca. 1995. If not, this isn't the first time I've been wrong.

I can take pics of the guts of it & post them for expert review, since I wouldn't know what to look for. the 2.93 turns _much_ easier than the 3.46 does. the 2.93 is very smooth, but I don't recall whether the 3.46 is rough or just hard to turn. I was mostly concerned about draining all the fluid out of them & cleaning them up a bit, since I knew I didn't know what to look for in the way they operated.

Seal friction clouds the issue. Backlash is measured with a dial indicator. Without that you should feel a tiny bit of play between the gears.

I think it's a European Escort, perhaps a Cosworth if it got going at high enough speed to kill itself like that. note the 4-lug wheel." The Ford Escort of 1990 was one of Ford Europe's least capable offerings, particularly at launch. It was infamous for, amongst other things, a flexible chassis prone to buckling and with little torsional stiffness to speak of. This, therefore, may have been nothing worse than some very untidy parking.

I might know of one locally (NE Ohio) that could be obtained for $800 or so from a 1989 325is with 130k miles. I will need to verify the condition but it is reported to have substantial service records for my perusal and I should be able to test the compression/leak down before pulling it. Any interest in it? Later, Rich ------------------------------ Date: Tue, 5 Aug 2003 18:28:08 -0400 From: "Pharr, Jeff" <[EMAIL PROTECTED]> Subject: RE: [uuc] <E30> differential repair questions Brett, thanks for the info. I just had another go at the diffs and here is what I found. Diff 1: 250K miles on a diff from a manual iX. Turning the input shaft takes about as much effort as spinning a wheel hub. And if I try to spin it it will coast for about a half a revolution. If I grip one of the output shafts I can still rotate the input shaft but it takes a bit of effort. Diff 2: 150K miles on a diff from an automatic iX. Turning the input shaft takes about as much effort as spinning a wheel hub that is really dragging against a brake pad. It will not 'coast' at all if you try to give it a good spin. If I grip one of the output shafts, I cannot rotate the input shaft at all. I am beginning to think that Diff 1 has a worn out LS (is this a replaceable part?) and that Diff 2 has some sort of a problem with the input shaft that is causing the dragging that I feal. I guess I will just go ahead and use Diff 2 and see what happens but I hate to miss something that is easy to fix while I've got it sitting on my garage floor. Thanks again to all who have replied. - --Jeff > -----Original Message----- > From: KMS - Brett Anderson [mailto:[EMAIL PROTECTED] > Sent: Tuesday, August 05, 2003 1:32 PM > To: [EMAIL PROTECTED] > Subject: RE: [uuc] <E30> differential repair questions > > The iX diff has a viscous coupling, but it's like the E46 M3 unit, in that > the viscous coupling creates the pressure that is applied to the clutch > plates.

Front P/N: 86-2277 SP1. Rear P/N: 80-2522 SP1. They have a 1 hour race, a 30 minute race, two schools, a couple of autoxes and some minimal street miles on them (driving to and from events). The bodies have a couple of scrape marks from my ham-fisted installation and removal otherwise they are excellent. Although they are E30 M3 inserts they will fit other E30s (like my 325iS) and according to Lee Grimes from Koni they are valved a bit more aggressively for the E30 M3, could be a good 325i upgrade. They are hydraulic so they are not top adjustable they need to be collapsed, you can also revalve these. :-) $325 + shipping from the Detroit area (48034).
