Thread damaged
Just had the same problem with the Busa. The next size up is probably 5/8" so get yourself a 5/8" sump plug from Repco or Supercheap & tap it out to that. There is plenty of meat in the sump for it but you will have too little to go to the next size in metric if you manage to find the next size sump plug in metric. I was advised the thread inserts would come loose due to the slot for oil drainage by experienced engine builders.
Good luck.
