If you got deep pockets, this is what I would order up:
1) A EURO spec differential housing (pumpkin): 38301-EH53E (this rear diff has fins in the cast iron bottom, never seen this on any other R200V before)
$1,800+
2) Rear diff breather (this has to be pressed in): 38356-JL00A $5+
3) Nismo rear diff AL finned rear cover 38351-350DK $125+
4) Silicone vac hose 6mm for the diff breather ~ 1.5ft $7+
5) OSG Super Lock LSD: D-NB102061405-S $1,400+
6) An additional LEFT flange for the OSG LSD: 38220-JK01B $140
7) Sensors, anti-skid rear (if needed?): L = 47901-1BB1A; R = 47900-1BB1A
$180ea
8) Nissan Frontier final drive gear $500+
(3.916 = 38100-0B66A; 4.083 = 38100-0C760; 4.363 = 38100-0C860)
9) Diff assembly by professional trans/rear end shop $300+
10) SPL rear differential bushings $165+
After this is all assembled and installed your looking at a bill over $$$five large$$$.
