I got an S4 Clutch type LSD center section the other day (center section only, so no rear portion/cover/mount or stub shafts for the half shafts. I am wondering i can do anything with this to adapt it to me 88 NA diff? I have read that LSD guts into an NA case will not work, but will NA cover/stubs work with LSD center section? Is it simply better to find a complete S4 LSD than waste time trying to make this one work?

Thanks in advance for any help!

 

Nothing will work, everything is a different size.

You're better off finding a complete diff

 

I already have the mazdatrix na trans to turboII drive shaft. So I can't use the cover/mount end from my na and bolt it to my lsd center section? I know I would need to order s4 lsd snub shafts. I also already have turboII half shafts.

 

You're trying to mix and match stuff that won't fit anything.
The N/A to TII driveshaft will need to be attached to a TII Diff.
So why not save everything and get a TII Diff,since you say you have the axles already?

The Axles will fit the rest of the car no problem.

 

I have the s4 turboII diff, when i say center section i have the pinion, housing, lsd, only thing i do not have is the other half which resembles a cover to me on a traditional truck differential w/ the integrated mounts. Hopefully images below clear this up, this is what i have currently from the TurboII, plus the halfshafts and i have my complete NA diff.

you cannot use the "cover" from the na diff to answer your question, the t2 "cover" is larger, due to the internal ring gear being an inch larger.

3 options
1 you either need to find a na lsd and swap it into your na diff, reuse driveline and half shafts
2 find a na lsd rear diff , reused driveline and halfshafts

3 find a complete t2 rear diff, (I doubt youd find just the "cover" for sale), then get a t2 driveline, and t2 half shafts

I see the t2 stub axels in the pic, you need the whole shaft that goes to the hub, just to clarify if u have those or not?

 

I do not have the them, but i have a part number and could get them

 

NOOOOOOOOOOOOOOOOOOO!!!

why did i crap my cover to my diff 3 years ago.. why did i assume i wil just snag another one later... gahhhh
