Mechanical LSD

[indecisive]

The S13 R200 LSD for OPEN DIFF will go into the S12 R200 open diff.

Don't need to change anything. Remove the diff, take it apart, put the new LSD in, and put it back together and your'e good to go.

Note, this is for the R200 Diff...

edit: wait, did you mean the aftermarket Nismo or kaaz 1.5 way Clutch LSD, or the factory option VLSD? The VLSD will work, but you need to frankenstien together a combination of S13 and S12 shafts.

IMO, not worth it, rather just go for the aftermarket clutch type. its a better lsd and less work.
