So m30 in e30? Or one of the smaller e28's or something? All my big m30 cars came with a mid-case.

Someone who's cheap. M30s can be had for next to nothing and with some lengthened harness wires it is plug & play into an e30. But the M5x motors are objectively better in almost every aspect except longevity (M30s can take some serious loving abuse) so no one really swaps them anymore.

FWIW, I once test drove an M10 turbo making about 235whp that still had the small case diff. Didn't sound too healthy when I drove it. People just do big power mods without considering other things.

Having seen someone do an m30 into an e30, it most assuredly isn't plug and play, at least not on the mechanical end of things. My argument for m30 vs m50/52 would be that they have an assload of torque and are really easy to turbocharge. But I'm biased I guess. It's a dumb thing to do because it trashes the handling on an e30, which was my main concern when I drove the end result.

Oh and the m10/m30 bolt pattern and flywheels etc are the same which gives you a bunch of gearbox/clutch options. M20/50 is much more limiting.

Or someone who really wants a 4+ final drive ratio and an M30 with the minimum of effort?

Always wondered what the M30 swaps actually drive like. Isn't the M30 both vast and heavy? Even if you get the suspension sorted (an expensive 'if'?) I would worry that they'd just plow straight on in every corner. I mean obviously you can drive around it, but is it really a pleasant experience?

It really is pretty ratshit. From an all-round awesomeness perspective you really want either a turbo m10, an m42 or an m5x. The m30 has it's place though. Namely in a sharknose car with a turbo/blower on the side, a 4 speed rock crusher from an e12 behind it and an LSD medium case with 3.25 gears behind that.

I miss having an old BMW :sigh:

E30 320 and down with open diffs use small case where as the LSD's are medium case diffs. 323 and up use the medium case on both open and LSD diffs. Or at least that is what I've been told. This was a M30 in a 318 IIRC.

I've never seen an LSD medium case in an e30, but I'm sure they exist. All the ones I've seen have been open. M30 in a 318 is a terrible idea, especially because it has suspension softer than a 6 cyl and the shittiest brakes available. The only upshot is plug-and-play gearbox, provided you build up an m10 clutch/flywheel combo that can deal with all the torques in the world.

Every E30 325es/is should have a medium case LSD no? They do in North America anyways.

We never got is/es, all the 325i I've seen are either ordinary or 'm-sport' and have the associated bodykit, seats, steering wheel etc. 323's are pretty rare here so I can't comment on that. We have an e30 race series where they're allowed to run either a 320i or an m40 318i and they must get their lsd's somewhere. It's a hilarious class, they can go hog-wild on suspension and chassis but the engine and gearbox have to be totally factory.

My sister's '96 Corolla recently had an A/C belt shred itself off the pulleys, I took a look at it and saw that the alternator belt wasn't far behind. Since the timing belt hadn't been touched since '06 / 70k miles I figured I'd go in there and refresh everything all at once, and I'm glad I did..



Crank pulley, shot from the passenger wheel well. Looks like something from the wreckage of the Titanic, but it's pretty standard for something that has lived in Ohio for 16 winters. (you don't wanna know about the rear wheel wells)


Hey, the pulley comes off the crank pretty easily! Wait a tick, I haven't taken the crank bolt off yet...



I've never heard of a crank pulley failing this way... at least on the VW's I've worked on. You can see evidence of the pulley "hunting" back and forth; shiny scuff on the engine block and burnt plastic on the timing belt cover. More than likely it's the cause of the belts shredding off, I'm just glad I caught this in October rather than February.

It's not the most common thing, but it does happen. There's a bit of rubber between the two pieces (which is why it's also referred to as a harmonic balancer on a lot of cars); when it rots away, they split apart like that.

And yeah, that's likely why it's tossing belts.

I had this happen to my crank pulley, it went the other way and chewed up the timing belt.

My Grandma's 1996 Corolla that looks exactly like that had never had the timing belt changed until march of this year when I finally managed to badger her enough to get her to let me do it. Belt must have been at least a little stretched because it runs much less shittily now.

The service centre for one of the dealerships here has a big section of their wall which can be opened and pivots vertically on a central axle / hinge. It's always open for most of the year. I suppose it would be the difference between brain boiling and a horrible workplace which can still sustain human life.
