ok, so here's the deal. my friends (i helped some too) built an s13 with a 5.0 out of an 89 mustang in it. it's running on its own power, and it's a drift car.
here's the problem: the 2 way lsd in the s13 is 4.10 gearing. too high, and no traction with 245 tires. While traction's not an issue, the gearing is too short.
So... my question is this: does anyone know if earlier 3.36/3.54 280Z r200 ring gear will work in a later r200? Or if any other differentials with lower gearing will work as a bolt in?
