Right over here in Puerto Rico I found this guy that is selling me a 200sx differential. I want to make the convertion to a 4.11. I want to know if the differential of a 200sx and a 200sx turbo is the same? The one that I found is from a 1985 200sx non turbo. Is the same differential? If it is, what are the modifications that I have to make to make it fit in my 1981 zx?

 

looks like the diff is a R180... check this link:

Sweet Z efrain, verry clean looking! I like the door panels, those are unique!

 

85-86 TURBO 200SX ONLY. If it's a non turbo and has the stock diff, then it's not what you want. It may or may not be a 4.11, but it's definitely not a R200 with a 4.11 if its the stocker.
