ok 3:73

but i have a 88 turbo coupe rear end laying in my yard what gear shoould be in there and would it fit in my SC aod
 
MY 89 SC HAS THE 2.73 GEAR RATIO, 5 SPEED
I LIKE IT SOOOOOOOO MUCH!
I WOULD RECOMMEND 3.73's IF YOU WANT YOUR SC TO TAKE OFF FAST FROM THE START.
 
WHY DON"T YOU STOP SHOUTING

And where the heck do you get new gears for $130? Maybe $170...

As for the tc rear end, I don't think that will fit into our cars, sorry
 
you cant swap in the whole diff but you can use the gears from the turbo coupe if its from a 5 speed it had 3:55 if it was a auto it had 3:73 you might want to check how worn they are before you swap them

Only if it is a 8.8 inch rear end!
