s13 rear diff ?

[mac2686]

Does anyone know if the gear ratio is in the stock s13 differential is 4.06. I understand it's known as the r200 but there seems to be many r200's with many different gear ratios. I'm also wondering what the gear ratio is in a 95 J30 rear diff assuming that it is not 4.06.. Would I be able to change gears from the stock s13 diff to the J30 diff if they are different? Thanks

okay I just found out that the stock s13 rear diff. gear ratio is apparently 4.083636 and the stock 95 j30 gear ratio is apparently 3.91666. So if all that is correct those numbers are pretty close do you think that the j30 gear ratio would be okay in my 240 which I'm also turboing??

don't think it'll make that much of a difference.
