I think 4.3 is already present in some old RS200 Altezza (very hard to come by). Not sure if it will exactly the same specs in order to fit but it might worth looking into it. Weir Performance had something similar. Otherwise it might be just a matter of waiting for some kid with a 2017 one, run out of talent and pick one up cheap from wreckers in your area.
With that said however, for a manual 4.556 final drive is better in my opinion and priced well. (toyota part)
I have done mine and could not be any happier.
