Cusco Lsd Help Needed

[chinna]

hey guys

i am buying a cusco 1 way lsd for my r200 open diff

problem i have run into is the lsd for a HR31 and R30 long nose

are listed as different part number by cusco

hr31 is LSD 162 f

and r30 models are LSD 161 f

i have looked every were and no one can tell me what the difference is

i have brought my R200 from a HR31 from what the seller said

and it was an open diff which i know some came out with in the lower spec ones.

the only thing i have been told is that HR31 the crown wheel bolts are 12mm

and r30 are 10mm is this right

thanks

I believe then only differences between any of them are the crownwheel bolt sizes, which can be easily rectified with sleeves, and the position of the half shaft circlips.

My best guess would be that the circlip positions would be the same between those 2 models, so the crownwheel bolt sizes would be the only difference I would think. This can be sleeved easily enough.

dr30 r200 crown wheel bolts are definatly not 10mm. they are 14mm.

im not sure on differences but my mates hr31 has same diff as my dr.

both styles of cvs are interchangeable.

wouldnt bother with a cusco 1 way any way, just add more clutch packs

i am getting one though a mate from japan cheap brand new

my diff started life as an open long nose i though the bolt size was the only difference thanks for the help

i don't want 2 way its just a weekender
