Which car do you exactly have? the n52 in 3.0i trim or the n52 in 3.0si trim?
The (manual) n52 in 3.0i has a 3.38 final drive and the (manual) n52 in 3.0si has a 3.23 final drive according to the spare parts catalog.
So I think there's no possibility you have 3.46

3.91 is afaik a ratio used in the e36, not the e46.

Are you gonna do the swap yourself?

What kind of races are you loosing at the moment?
