91 Leg turbo Rear diff-lsd?

[bmxpunk]

I found a 91 Legacy turbo automatic. I was wondering if the automatics had the rear limited slip diff. Is there any way to tell via vin number or something, since I think the sticker on the rear diff is gone.

I belive all the 91 auto or 5 speed with LSD at the rear. I got mine from 91 turbo auto.
You could easily to check with the silver plate at the diff. will be saying its a LSD with 3.9 or just 3.9.

Its missing that plate. THats why I need to know.

[Legacy777]

yes, it should be LSD.

Does it not have the rear cover on? You should be able to tell by looking at the internals.

[bmxpunk]

It has the cover on it, but the sticker is gone. I am thinking of buynig the whole car and parting it out.

The next question is, is it geared the same as my 93 5mt would be?

[Legacy777]

no

[georryan]

Well that depends. If your 93 5mt is a turbo then probably yes, unless you did swap or someone else did. If it is a NA then no, it is not the same gearing. (assuming your 93 5mt is a legacy)

ok went back out to look at it. It has the sticker on the diff and it says 3.90. Is this the same as the 93 Legacy SS rear diff with a 5mt? If not, what does is my diff?

[Legacy777]

So your 93 MT (n/a) is 3.90?

The 93 SS should have a 3.90 final drive ratio.

No See I have a 95 impreza with the entire Legacy Turbo engine -tranny-dirvetrain-brakes swapped into it. All Of my running gear is from the legacy turbo. Thats why I figured If this diff was limited slip, why not throw it in now.
