Ke20 Compliance Plate Info (Diff)

[flyinwall]

i am trying to find out what diff my car is meant to have had in it and i want to know if anyone knows what the trans axle codes mean on the compliance plate

 

the number on my compliance plate for TRANS AXLE is 4F1 . B092

 

can someone please help me

 

and what diff ratios were available from factory as the the diff i have here (from what i can figure out ) is close to a 2.* -1 ratio
