All 325i sports should have an LSD, an 89 car should have a 3.91 ratio LSD.

so the diffs a bit lower geared in the auto? i guess if i put a manual box in it then it will rev out quicker than a manual sport

a 3.91 would rev quicker than a 3.73. seems like an odd way round to me, always thought autos were geared higher to aid acceleration

they are on a standard 325. 3:64 on a manual, 3:73 on an auto.

Don't forget the US spec M3's and alot of the US spec 325i autos come with the medium case 4.10 LSD's as well.
