s52 Swapped Hatch LSD...

[HyperMikeD]

Im in the process right now of swapping an s52 into my '95 hatch and am trying to decide what diff to use for my setup.

I recently bought two LSDs from an e30. One is 4.10 and the other is a 2.73

Now I found an 3.73 LSD out of a 1984 Euro 3.5L M6 that I was thinking about buying. The owner says it is a "large case diff" which to me means 210mm. I just cant find any info that says this is in fact 210mm. I would like to buy it but if its not 210mm then I will just use one of my other diffs listed above.

Thoughts/suggestions ?

Thanks.

Look it up on realoem, it should say what size it uses.

Unless youre boosting that s52, and even then, the 188mm will be fine with that gearset. Im running 4.10 in my 325ti and it pulls through gears like nothing, a bit too quickly sometimes. Id step down to a 3.73 but dont feel like buying another diff since its in the C57. If i were you, id just pull a gearset from an open E30 3.73 and install it on one of your Ls units.

Well this is actually my setup out of my boosted '95 M3 which is getting an LS1 swap over the winter. :biggrin:

Ill check out realoem...Thanks for the suggestion.

Cheers !

Powdercoated my diff cover and installed the poly bushing from AKG Motorsport.

Old bushing was a PITA to remove...I guess its SOP to burn them out huh ?

Also bought some replacement SHCS for the speedo sensor bracket.

Cheers !

I just wanted to share some pics of my differential that I started restoring. I used Evapo-Rust that I bought at Northern Tool and the results are pretty amazing !
