2way diff for non turbo S15. What fits??

[-BigDave-]

Rights lads. I'm finding it difficult to find a 2way for my non turbo s15. From doing some research i have found that an R200 differential will fit in my current casing. Is this correct?? The R200 is the diff found in the 180sx so can i recase a 180sx 2way into my on casing?? Its ****in confusing stuff!! If im wrong on all the above can someone tell me what diff from what car will fit in my casing please

why not just get an s14 or 14a casing and drop a diff in that - i'd imagine the ratios in a spec s to be pretty much that of the 14 5 speed if not the same soshould work well. if the s uses different half shafts then these are pretty much given away secondhand too

i'm pretty sure i have a cusco two way in a s15 non turbo casing, if that helps.

I cant say for sure with non JDM, but anything that fits the spec r will fit the spec s, you wont need to change half shafts. I have a helical lsd (Spec R) head in my spec s casing, straight swap, ring gear and spacers from your current set up match right up. I have done this twice to Spec S diffs so i can say for sure that it all fits. And if you use you existing ring & pinion you wont change your ratios at all

So you reckon if i get a 2way for a spec r, i will be able to recase that diff into my spec s casing?

If a HLSD head from a spec r is a straight swap into spec s diff casing why would any other head not fit. For peace of mind ask a company that sells these types of diff and ask them

Any Nissan lsd will fit in if it's for the r200 casing.. U just need the output shafts to go with what lsd is designed.

For example I have s14a kaaz 2 way in my s15 casing with s14a output shafts..

S13, s14, s15, skyline, 300zx etc. Are r200..
