Lsd carrier should swap right in R200. No mods needed just some labor. Old parts fit right in.

Does this depend on the lsd or ring and pinion gears? Lsd is 3.7. Ring and pinion is 3.9.. where do I stay at?

Not sure what your question is... LSD = Limited Slip Differential. It's not the gear, it's the locking mechanism. If you are using a stock Z31T LSD, then it's 3.7:1, if you adapted a 3.9 gearset, then you have 3.9.

If you purchased a complete R200 carrier (with LSD differential case), then it already has it's own ring and pinion gear setup, which must be labeled as a 3.7:1.
