How Much Gearbox Oil To Fill Rb25 Box?

[FATGTS-R]

Tried searching and found a few different answers so hopefully someone can clarify.

Have a bone dry R33GTST box thats about to be bolted to my engine and want to know how much gearbox oil to buy?

Have read anywhere from 2.4litres to 4 litres. The oil I am getting comes in 1 litre containers so dont want to have too much as its not cheap and I wont be changing it again anytime soon.(I hope)

I put a bit over 3.5L into mine when I changed it, prior to that I had heard anything between 3.8L and 4.1L..

If you bought 4L and it accepted every last drop you would still be pretty safe, 100ml isn't going to change the level much.

I just filled mine up. Got a big bottle of Redline Lightweight Shockproof and it took all but about 150-200ml. So I think that's about 3.7L cos the bottle is 3.9xxx L (American sizes).
