If you had the opportunity to regear your transmission. And had the choice of either having the gears replaced with your factory installed transmission or having a new transmission swapped out all ready to go.
The reason why I am asking is because "Orbit Racing" is developing a core exchange package (which would speed the process dramatically), whereas you can just get your Tranny swapped out in a day instead of taking apart your original Tranny.

The swapped out unit would be new, all the synchro's and gears would brand new from Porsche Motorsports. Thus, saving money because it would much less labor involved.

The question would be does not having matching numbers be an issue?
