Not Ranked
I am running a VN commodore BTR diff with a Torana setup in a Homebush kit, on my third ratio looking for more speed and pull out of courners, started with 3.08 went to 3.45 and now running 3.93. The 3.93 is a skyline crown and pinion, just need bushes to make the bolts fit snug. I have had these three ratios in 6 years ????? 
Motor makes about 350 HP or 370 KW ( photo attached) and every time I change the ratio the bearings are f...ed, but never had a problem while driving.  I am running synthetic diff oil.
This car is mainly driven at maximum revs on weekends at the track. The diff is stronger than the gearbox ( broke one of those) the adjustable upper arms (photo attached) as I broke both of those the other weekend getting in some burnout practice. 
I would recommend the BTR diff ( VN) the most suitable and cheapest.
Good luck
