Yep, e53 oil pan and diff.

[nando]

using what diff/oil pan? E53?

[stonea]

525ix comes with a 3.38. With a ZF it's similar to a G260 and a 4.10.

3.64 and ZF would be horrible together! that would work on a 6 speed.

I keep going back and forth on whether I want a taller ratio or not with my G260. it's not like I DD it or drive it long distances. The short gearing is a blast around town and on back roads. 3.91 would still be plenty short, but I already have good working 4.10s.. and with a 7500rpm redline, it would be fine.

I was thinking a 3.23 with the Zf, if the e46 gears in a e53 works out. If not I think I do the G260 with the 3.64.

Also, I have no clue about the ring gear bolt torque procedure, or where to get the bolts. That difficulty can probably be fudged though.

I have an E46 3.23 front diff on the shelf.
3.64 is a decent ratio for use with the Getrag 260, which can work with the 24V engines with the right front case.

I really wanted to use the Zf with the 525ix stuff, but if I can't get anything other than the 3.64 ratio I might just stick with the 260.

I got the Weichers aluminum bar :)

[nando]

M3 maybe.. when looking to buy a strut bar they all show all e30 models except m3/ix. I still cant find one for an IX..

weichers sport... it's been around for ages. I think Bavauto sells it with their branding on it.

M3 bars will not fit. the only reason they might have a "different" bar is because of the engine, the basic chassis of the E30 M3 is identical to the standard E30.

I *THINK* you can put the gears from an E46 into an E53, but you have to use the E53 carrier, as it is a different width across the carrier bearings than the E46.

The bearings will be some sort of standard parts, but good luck finding shims to do the setup, or a crush sleeve, as BMW never published service information for the front diffs.

A Quaife for a Z3 4 cylinder supposedly fits the X5 front as well... although you have to take the Quaife apart, flip all the gears and put it back together to make it work correctly turning the "opposite" direction.

Well at least that gives me some hope, lol. I found a cheap 3.64 ratio diff that I think I'll pick up and hopefully I can find a 325ix being parted out or in a junkyard. I really like the idea of the Quaife in the front, hopefully that pans out. Once I start collecting parts let me know if you want to borrow them for measurements or mock-up. The E30 is my daily so the parts are just gonna be siting around collecting dust until the time comes to park it and swap it.

Since the thread was brought back up, does anyone know if you could transplant e46 front diff insides to an e53 x5? I really want to use the e53 x5 oil pan since I'm basically using a M54, but I'm not 100% happy about the 3.64 ratio.

I kind of agree, the strut towers look like they're too far forward for some reason

The iX strut towers are father forward than the RWD ones, so I don't know what E30 that would be that has strut towers that look further forward than an iX's... :p ;)

It does look like a RWD body, though, as there isn't much space between the battery box and the strut tower.

HOWEVER, AWD or RWD doesn't affect the measurements that Nisse showed.

[Nisse Järnet]

Yeah I just took a random E30 pic, not mine :)

[6A LDY]

that doesn't look like an ix to me. did you borrow this pic from somewhere?
