BMW 525ix diff in 325ix?

[CrazyPrime]

I know the front diff is the weak link in the 325ix drivetrain, I was curious if the 525ix diff will bolt to the 325ix pan? And if the axles and front driveline will work also? Or if I will need to have a custom 525 inner and a 325 outer axle made? Thanks for any input guys!

it will not come close to directly fitting. also the 5er ratio is 3.38. ix's are 3.90, 4.10, and in rare cases 3.64. 525ix axles are all but impossible to find. there is a pretty long thread here about doing 24v swaps in ix's. you might give it a read as there is info there about using 5er parts.

Is there some problem with your front differential? Unless you have to put major HP through it, I am not sure I would agree with the blanket statement in your question.

If someone has stayed on top of their fluid changes, no reason the front should fail any more than any other part of the drivetrain... and if it does, just replacing it would be the easiest.

Yes I am aware of that, I guess I will just see if the diff can take the extra torque of the turbo. If not I will have to devise a alternative.

I have also a good amount of hp and i am wondering a good alternative to improve resistance of the front differentiel on an ix. Maybe also get an limited slip diff would be awesome, probably i will have to machined my own carrier.

well, good luck with that one. price it and get back to us.

That dude from Finland with a 600+hp was breaking diffs on the reg, he said he somehow added 2 more spider gears to the front diff 4 all together. he said it has held and the spider gears haven't broke yet but the ring and pinion has recently broke. I wont have 600hp but I would rather have safe of mind when launching, autocross, drag. Then worrying about breaking my diff all the time.

I want to sell my 525ix stuff if someone is interested. I have diffs, oil pan, and cv shafts.

Also, everyone always talks about lsd for the front, but im pretty sure there's a reason you dont want one.

I don't get it. The iX is superior to so many vehicles in its class. Yes, I am adding power to my 88iX. AWD DSMs are four bangers and can take much more abuse than the iX. But the iX can take turns like a train as long as denzel isn't driving. I nerver had a RWD e30 and I do want one. I don't want to blast part some clown and then say "oh yeah, its a rare AWD BMW"

I'm so confused.

[CrazyPrime]

Dude same here I have no idea what he just said..... 😵. Nando why you selling all your 525 stuff? Wont work for a m50s50 swap, may be a stupid question but does a m50 oil pan bolt on a m20 block? I apologize in advance if I sound like a moron lol.

I was trying to say there are other cars with AWD to spend money on and blow up.

I'm Jesse.

Or I could build a 325ix and not have a shitty rice burner dsm. That's also a possibility...

Yeah I know they (DSM) are girly cars. I'm just saying the iX is an awesome machine. It took a long time for me to get one for each year.
