Default 91 Legacy turbo rear diff swap to wrx question.

The car is an 04 wrx with a JDM v8 6spd swap. The 99 legacy r160 3.90 diff just went out recently.


At the moment I have a 91 legacy diff ready to go in but I am not sure if it's true that this is a 3.90 ring and pinion also? The person I bought it from is unsure as well. Does anyone know?

My brothers 91 Legacy turbo Automatic was 3.90 vlsd. I am pretty sure the 5mt ones are also but I am not 100%.

Early 90's legacy turbos were a 3.90. If it was a 91 turbo model it should be a limited slip. The NA Legacies of the same time were 4.11

The more I think about it I think the Wagons were non lsd. But all 91 Sedans are. 92-94 were all non lsd.
