Eta owners with diff swap?

[Bimmerista]

I had a 3.25LSD in my 86 325es. It was perfect. At 65mph on a flat highway I would get 36mpg with no A/C on. About 30mpg with A/C.

Gotta love an eta! Reliability and fuel economy are where its at!

I've got a 3.46 open, if yours is an LSD you can swap your guts over. 3.46 and 3.64 are 2 of the hardest to find ratios except for 4.27, 4.45 and other silly stuff like that.

There's a way to make an open dif into a lsd? Does anyone know of any diys explainig this. I always thought all you did was take the insides of the dif and swap em with the new ones. Didn't know you could combine the two. Anyone try this?

i still haven't checked to see if it was lsd or not but I'm pretty sure it is cuz my burnouts are like this "ll"

Has anyone tried this? I thought you just swap everything that's in the casing lsd or not.
