Help.......!!!!! 240sx 180sx 200sx rear diff Differential info needed pleeease..

[ait300]

Hi 2 all….

I am looking to weld the rear diff on my newly purchased late 1993 s13 180sx (240sx) with SR20DET. (Non ABS)

There seems to be a lot if confusion about the S13 rear diffs, some being non VLSD and some having factory fitted VLSD.

I am pretty sure that my car has VLSD purely due to the way it drives and feels, plus I have lifted the rear wheels and YES they do turn together at the same time…

I have had a look underneath the car, and noticed that the output shafts had 5 bolts and not 6 which confused me even more as I was expecting it to have 6 bolts…..

I need to know….

1. Is the current diff in my car a factory diff…..??

2. If not then, which diff is it and which car is it from….??

3. Can I weld a VLSD diff and where do I make the welds….??

4. If i don’t weld my current VLSD, Can I use the internals from a S13 OPEN DIFF to weld and place them in the currant diff casing on my car, saving myself time from changing the whole diff casing as well as the shafts?

What ever info you have please keep me posted as I will be starting work on the car soon.

Thank you…………
