The R230 is LSD but don't know for sure if it's viscous or not. You will need to modify the shafts to fit, but I have the shafts from this diff as well, they are huge.
I think it's out of a 300ZX twin turbo. (3.7:1 is the ratio)
Hey Nismo32, what's it going in?
If it's not going into a GTR, I have a R230 which is bigger & stronger than the GTR diff's for $400 + freight.
I'm in Wollongong NSW.
Never used & stress free, still in the crate, $450 FIRM.
Block only, that means no crank, rods, pistons, head, turbo or gearbox, etc.
