Need help whit an cracked differential on e30 325i from '86

Hi there..I have cracked my differential :-S and the thing is the engine is from an e34 made in '95,the gearbox is from an 3.0 diesel..Could be any chance to change the differential and which one is better 'cause in 1 and 2 gear the weels are melted in ground and..that why it broked!

look for a diff out of an 325es/is with a 5spd.

Are u sure that if I'm gonna take one differential from a 2.5 e30 it will work and not brake down?!The thing is all the interior is changed,same as the exterior..same as the power and honestly I still want to beat a lot of cars ;-)

Good - fast - cheap. Ring any bells? Maybe a '7' diff will give you the reliability you seek.

I have a little-known about the diff but I want to get one..like 4.27 if is good..I think I had an 4.10 that's what the boy told me when I bought the car..or should I try 3.73?The thing is I still want to beat 330ci e46 and 328i e36 and lots of robotical cars :-D
Thank u a lot and sry for my bad english

Use a diff from a 5 or 7 if possible. They should handle the power you have and the abuse you intent giving it.

Thank u very much..I just need one last answer :-)
I don't have ABS on my e30..is there any chance I can put one or should I try bigger disc brakes and ventilated?!

abs is normally based off the spindle not the rotor. up front bigger brakes are better, rears are kinda a waste of money

You would be working in your garage for months to install ABS.

Thank u very much my friends :-) Wish u all the best and..if I'll have any questions on the future hope u'll help me :-)
