@Ivan. indeed in Japan the gearings are much cheaper, founded some SC gearings 3.7-3.9 and for NA 4.55 and 4.77. I think it are TRD ones.
Now i have an good contact for importing stuff from japan
The prices are reliable, for about original here you can get 2 from Japan.


I'm only searching for an nearly standard gearing, but what is standard? The 4.1 or the 4.3? I'm thinking about the 3.9 one, and make some more power then

And whats the precise difference between the prefacelift and the facelift diff? Is it possible to swap the gearings between those 2?
