400Rwkw, Will Stock Diff Hold?

[Andrew.Y]

Currently chasing 400 rwkw and was told the stock diff will not hold for long. The car is 99' GTR non-vspec. I was under the impression that mechanical diff can hold a bit more than Vspec diffs.

So will the stock diff hold the power alright? If an upgrade is recommended, what then?

Thanks.

So far as I know Rips big power (500 + kw) RB30s still use stock diffs and axles.

Of course the diff is strong enough to not break. But as with any plate type LSD, as you use it, it wears and the LSD action decreases. On old diffs with big power, that simply means it gets to the point where it won't stop you from single spinning it.
