Hey guys-
So as I currently have my s52 e30 finished and up to par- the 4.10 open diff that was stock on the 325icA is not going to cut it. 1st gear is non existent, 2nd is first, 3rd is like 2.5 and 4th is like 3rd....pair that with an open diff and it's not fun, it's depressing.
Anyway, I've been searching for a 3.73 through 3.23 LSD and striking up empty handed. But today I was able to land a precious find- had to bare the snow in one of the coldest days of the year- a 3.46 4-bolt 188-Medium case from a 1985 e23 735i. Unfortunately there was no ratio tag but determined it was an open case, which sucked but from what the 24v people say- it's the best ratio to find.
So here is the thing. I currently have in my possession the following:
1. E23 735iA 3.46 Open Medium Case
2. E36 M3 3.15 LSD Medium Case (From S52 donor w/ CV Flange)
3. E30 325icA 4.10 Open Medium Case
So here is what I am thinking- Is it possible to remove the LSD from the e36 case and transplant it into the e23 case? Thus making the 3.46 LSD. Leave the diff cover out of the equation as I will take the one from the 4.10 that is currently installed.
I've been spending the night doing research and trying to figure this out.....It seems that swapping parts within the same "diff case size" family works, but I cannot find a definitive answer fas for swapping out the LSD mechanism.
And if this isn't feasible, I will continue my hunt for an LSD for my e30s52 and hope to trade all THREE of these diffs for an LSD that will work for my situation.
I appreciate any and all input! Now excuse me while I go wash off one of the worst smells in the entire world off of me- differential oil
