From what I remember mate, the only way to tell is to get the box out and find a number, I may be wrong but I'm sure I remember saying there is a code on the underneath which will tell you. Or get someone who knows what a close ratio box feels like to drive the car.

Theres a code on the bell housing, should be HM or HN i think.
Post the number on here and somebody will verify.
Heres the number on my sport box:

Try oze30, he's bought mine but might not need it as he's done the 3.5 conversion.

A Sports box will have either TNN or HM stamped in the bell housing outer edge. Anything else and it is not a Sports box.
