Again, it's not about the PS/HP..
special assign the short engine designations example n57T/N/Z to the detailed engine codes N57D30TOP / N57D30TOP(TÜ) !!!!!

again. 
you need typecode and n47/57 t/n/z together (as i said before)
no another way to covert t/n/z to detailed engine code.
because in different typecode t/n/z means different engines!
