Alrighty I have a base model 88. Now what i was wondering is, do I have to do a conversion to my rear end(gtu or tII swap) so I can install a cusco lsd or can i just get a cusco lsd and bolt it in. I know my car doesnt have a lsd stock and thats why im asking. I would like to get a lsd soon and I was wondering what all it would take in order to get it installed.

 

cusco for a miata will fit and non turbo rear end

 

so if i get a cusco lsd for a miata I dont have to do anymods, awesome.

 

well you will still need to use the stock 7" gear and pinion from the FC diff (and of course set the pre-load), but yes the Miata uses the same 7" diff internals.

 

WOW never knew that, up to what year miata will work? I'm guessing 90-99?

 

94+

Not sure of the new NC though
