Like the title says. Can I put a S5(889-91) non-turbo LSD rear end into an 86?
Let em know if it's possible before I get under the car. Thanx for any and all help.

 

As long as both cars are non-turbo, yes.

 

They are both non-turbo cars

 

yes, u would happen to have a 86 GXL would u? If so you already have an LSD

 

why are you swapping? is one blown?
if not i think you would want to upgrade to the torsen diff but it is unclear to me what you're trying to accomplish
anyway - yeah those will swap straight up

 

I have an 86 base model, 4 lug. I have a S5 LSD rear end and complete suspension.
I am swapping to the 5 lug setup so I can put in by Bridgeport 13b and have some better stopping power. I wanted to know if the rear ends fit before I started this all. I am looking to add an LSD rear end and I have everything to do so. I just wasn't sure if everything mounted up to the chassis the same way. I wasn't sure if the S4 and S5 were the same underneath.

 

i have a base also and wanted to know what you will need to do the lsd 5 lugs conversion?

 

hey, if you decide you dont want to use that LSD rear end let me know im looking for one...PM me if you decide to.
