No the f13/f15 box will be ok as long as you dont drive it hard from stand still and the ratios are good as well. obviously if your gearbox has been to the moon and back you should treat it to some new bearings, seals, and oil.

do you think i would need to uprate the driveshafts aswell?

no, people use them on redtops, so they should be ok
