[redsx13]

sorry, im sort of a newbie when it comes to diff names. is a r200 what comes stock on a 180sx?

[crash n burn]

any s13&s14, i dunno about s15 since its helical?, im guessing yes

j30, and half a dozen other rear wheel drive nissans/infinitis

but yes, you just need to know if its a 6 or 5 bolt flange, 5 being prefered

[redsx13]

so the 240sx has one. what is the difference between the 5 and 6 bolt flange?

The R200 is also used on Mazda RX-7's and an R180 is used on some Subaru's.The 5point axles tend to be beafier, and can be identified by the 5point star mounting pattern on the flanges.6 bolt axles have 3 ears with 2 bolts per ear.Obviosly these axle/ output shafts are not interchangeable.

I just picked up a 5 bolt r200 vlsd. Does anybody know by chance what oil is best to run. I was thinking of Kaaz or some amsoil 75-90 wt.

i think an r32 diff is also one.

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…………
