S52 finally!

[kronus]

Been wrestling the belt for 2 days.

what exactly is that bungee doing there

[parkerbink]

All pulleys are stock, bigger belt is due to the supercharger.

So, thanks to the difference in the S54 oil cooler housing & M52, the power steering pump mount is different & the alignment is off so the belts don't run properly.

I ordered an S54 power steering pump

Pry bar to the radiator trying to get the belt on is no fun.

is this legit normal? i've been super bugged about my front right needing 5mm more than the left FOREVER...ruled out subframe and lca/tie rods long ago......

My front fitment is very different L/R on my e30 as well. Replaced control arms, tie rods, rack, subframe to no effect.
Still confident my car has never been hit as everything vin matches/shows no sign of damage.

OP did you go bigger pulleys (OD) when you went aluminum? is It possible you might need a longer belt now with them?

The myE28.com guys said it's normal for the rear of that chassis.

As for other models, I could definitely see it being out a little after 35+ years of mechanical stress. But I don't know that I would consider it normal?

You measured all four corners? Sometimes cars don't sit perfect side-to-side.
On my E28 I actually have a 12mm spacer on the Left rear, and 15mm spacer on the Right rear to get it sitting even.

It's similar to this, not sure on advantages, more air in can't hurt.

Belt broke, took the AC belt out. New tensioner that came with the SC froze.

Before this happened I installed a big bore TB.

Oof that is rough. Surprised to see so much damage from a belt break. I guess it's better the pulleys fail then the components though.

What kind of big bore TB? Does this provide any power gains over stock, or just for throttle response?

Took all the other pulleys with it. The PS has chips. Water pump has a large crack.


I ordered all aluminum pulleys.

If they came with longer bolts, you'll probably be fine, however studs tend to be easier to live with.

If you want, reach out to them and let them know R3V sent you

You'll also want to get longer lugs, or convert to studs. Motorsport Hardware always has the goods...

Car is looking great, you basically built yourself a Z3M haha

What size do I need? The stock are 50.8mm. I think the ones the spacer came with are about 65mm but did not measure. What about nuts?

[parkerbink]

15mm spacer in. Except losing the short stud lock, I like it.

Nope, just the back 2. I'm ok with the front.

I ordered 15mm from Amazon, if they are wrong, I'll send them back and get the next direction indicated.

Are the fender lips rolled? If they're not, you do want to leave some space as you've noted.
