What year / month?

Yes, a B47 would work with some creativity.

Eletrical could be diffrent aswell as marrying the ECU. N47T and B47 uses the same chain

Btw, @enabled What software did you use to tune your N47?

Some later N47 used the same ecu as the B47, so compatibility is very close.

Amazinjoey I used genuine WinOLS and lots and lots of testing and logging.

I don't really see the point of replacing for B47 since the timing chain configuration is basically the same. If your engine is not in disasterous condition, you could fix it and save a good amount of money. Ofc you need to tear it down and check.
On what mileage/km did it snap?

Whether there were any strange sounds before the accident, in which driving mode it happened?
