sport diff

[diamondblacke28]

hello does anyone know what ratio a 325i sport lsd diff 1988 would be.

are the sport diffs diferent ratios or all the same.

and are they a straight swap for a standard diff.

is there any thing i should know before i attempted to swap mine for one

all reply appreciated.

All later sports (88-onwards) had a 3.91 lsd, all earlier sports had a 3.64 lsd. They are a straight swap, but it's fairly time consuming, much easier to do with two people.

Wasn't there a 3.73 as well?

you have stated on the spec of your car. early afm(air flow meter)apart from the bosch numbers whats the difference.

[Theo]

Thats not the spec of my car mate, those are some parts I'm selling at the moment. Not sure of the exact technical changes made to the AFM at the stage of facelift to be honest.
