View Full Version : FS: 535 BMW parts

11-10-2008, 09:34 PM
hey guys, for those of you that don't know I'm the one who bought SLK's e30 BMW and am going to be doing an engine swap after i get it from Die Frau.

I recently sourced a m30b25 engine from a e34 535is (very rare) and the guy that sold it to me did so because he needed to clear out some space. He also threw in the rear subframe, diff, axles, and drive shaft (he really needed space) and i'm hoping to sell them. I was wondering if anyone was A) interested in any/all of this stuff and B) how do i find out information on a diff? the lettering on it's little metal plate says "S3 64 109"... and it has a big white "S" stamped on it (indication of a LSD) I'm told that due to the rarity that its worth a pretty good amount. Also, the car had 12x,xxx km on it (~80k miles) when the engine was pulled.

here's what wikipedia has to say on the subject...

E34 Alpina B10

The E34 535i was introduced in Europe as a 1988 model but was not available in North America (http://en.wikipedia.org/wiki/North_America) until 1989. Production of the E34 535i and its engine ended in 1993, replaced by the V8 530i and 540i models. Despite the 535i designation, the M30 engine found in the E34 535i was actually 3430cc (3.4 liters). The car can get 14-17 miles per U.S. gallon (17 to 14 L/100 km) city and 20-23 mpg (U.S.) highway. A rare 535is model was available in some markets (not North America). It featured a limited-slip differential (http://en.wikipedia.org/wiki/Limited-slip_differential) and sport trim. Alpina

What year 535 is the diff from?

11-10-2008, 10:13 PM
i thought it was an 88, but now i'm not totally sure... i'll see if the guy that pulled it knows but i won't be able to call him until tomorrow.

does anyone know how to look up diff.s based on the numbers on the tag?

There was a 3.46 available that year with LSD for the 535. Based on the stampings found on the diff case, my bet is that's what you have.

S3 46 in BMW lingo is a 3.46 LSD. There was no e34 535is though, at least in the US. There was an e28 535is. Cool but I don't know I'd go as far as saying rare. (unless you mean without rusty rocker panels - that would be rare.)
That car would have an M30B34 engine. 3.5 liter inline 6. An e34 535i would have an M30B35. Essentially the same motor with a better electronics package. Neither engine is rare as they were the standard 3.5 motor. "is" packages were largely suspension, aerodynamic and interior upgrades. The drivetrain's were largely the same as all "i" cars produced. To get engine upgrades you went to an "M" car.
An M30b25 motor would be rare in the US as its a 2.5 liter version that was never sold here. Not very desirable though because of its small displacement. I assume that it was a typo on your part. I believe both the e28 and e34 came with the 3.46 diff as standard and the LSD as an option.

Edit: Oh and contrary to Wikipedia, I regularly got 20-21 mpg around town in my e28 535is

no, not a typo on my part. i was told, and perhaps wrongly, that it cam from a euro (grey market) e34 and that since it had the lsd that this meant it was an 'is', not just an 'i'. this may be wrong, but that was what i was told.

also, not that it's 100% fool proof or anything, but that was what wikipedia said too
A rare 535is model was available in some markets (not North America). It featured a limited-slip differential (http://en.wikipedia.org/wiki/Limited-slip_differential) and sport trim. Alpina

like i said, i may have been misinformed, but not a typo. i really would like to find out for sure though before i sell it... i don't want to tell people i'm selling something that i don't actually have

So did they offer a 3.64 AND a 3.46?

"So did they offer a 3.64 AND a 3.46?" Sorry, it had been a long day when I posted this. I misread the original post. BMW does make both as well as a dizzying array of other ratios.

I was thinking 3.46 when I typed my response. I had thought that to be a common 5 and 6 series ratio but on further reflection may be wrong.

A little more research leads me to believe that a 3.64 ratio in a 5 series would be rare in that it is numerically quite high. Most 5's it seems have much lower ratios - 3.46. 3.25 even 3.10. Depends on the engine/transmission combo and year/body.

I wasn't questioning that the car was an "is" model rather that you had typoed on the the engine designation. A B30m25 being a 525i and B30m35 being a 535i or is - however a 3.64 rear would be a possible ratio on a euro 525i model and unlikely on an Australian 535is model so maybe the engine designation is correct and the sellers model history incorrect.

Its hard to say exactly what you've got there. The other question you are going to get is what size case is it because 3.64 diffs in small cases were used in 2002s, 320is and early 318is. A 3.64 LSD would be an attractive upgrade for e21 or e30 3 series cars without LSD if it were in a small or medium case. It would be way too tall for most US spec 5 series cars. (At least based on a quick internet search)

that there could be quite

Yes, while not as desireable to the E30 S/M5X swap guys, it will still fetch $200 to $300. I was hoping you were going to say you had a 3.25, I need one of those...:biggrin:

He clearly has a 3.64 LSD.

To whom would this diff be most coveted by? To what cars should he be advertising this? Most of the older BMWs here are the E30...

E30 engine swap cars or E28's.
