Help With Diff Purchase

[konect]

Hey all !

Am going to be ordered an LSD in April and dont want to get the wrong one !

Car was originally non turbo (converted in japan) and has 3x2 bolt drive shafts.

Am I right to assume that it is a Non turbo Cefiro LSD. Kaaz make a freaking diff for everything so I have to make sure it is the right one.

Thanks.

i was reassured by henry at rms that if it was the wrong one then he would change it...

go by the plate in the car? or do nissan have the chassis number on file?

i dunno man i just had a guess and luckily got it right - manual turbo with abs, 1990, and it had 5bolt shafts... :S

good luck

Is it an R180 or R200? Was it converted from RB20E or RB20DE? Reason I ask is that mine was originally RB20E and came with a R180 open diff (3x2 bolts). Not much point in getting an lsd centre for that. if so i'd upgrade to an R200 with the thicker drive shafts. if it was a DE then its probably an R200.

I think you can tell by looking at where the flange thing bolts into the diff, I think the R180 is 5 bolt and the R200 is 6 bolts. (dont quote me on that) but also check ns.com.

I have the 180 converted to ATS lsd, and havent had any prob with the drive shafts, from what I know if you change it to the 200 then your drive shfts wont mat up to your hub as it requires larger hole for the spines.

double check though but I think thats right.

If your drive shaft breaks then just replace it. Cause really if your replacing the whole diff then its really only the casing left, your not going to break that.

You need to change driveshafts beacuse an R200 diff is wider than an R180.

There is no consistancy with the 6 bolt 5 bolt thing. I've seen R180 and R200s with either. Though i thought it was usually 6 bolts for an R180.

Hubs and splines are the same.

Yeah dude I lied, R200 diff comes in both bolt formats, apparently the R200 has fins on the backing plate, one way to tell. What I did find when I bought a second hand rear hub from a 300zx was that the turbo hub has a thicker diameter driveshaft and non turbo smaller driveshaft so Was thinking if you upgrade or whatever, make sure that it is has the same driveshaft size.
