So I've been driving a '90 525i AT (has the 4.1 LSD diff), just bought a '90 535i MT (has the 3.65 diff I believe)... question being, if I put the 4.1 LSD into the 535 what type of performance changes should I expect? The car already has the performance ECU upgrade, and I do plan on other various tweaks and whatnot when $$ allows. But as of now I wanted (kinda need) to put a new/better cond. diff into her (current one whines when under a load aka slowing itself down - when putting the gas to it she's quiet.)
Thanks everyone! I've missed you all, but the new man of the household has been taking up my time - anyone interested in pics let me know and I'll put up the shutterfly link to all his pics.
