Kexikus,
from the little I understand, I cannot make a .ncs file of the above .nss file. That's the problem...
In theory, I could extract the whole scripts.bif file where k_inc_man.nss is, change it there and then replace the original scripts.bif in the /Data folder of the game but I wonder if it is even possible to repack extracted files into a new .bif?
Alternatively, I would need to find the file in the game that does use the SetTokenRaceTime function included in k_inc_man.nss and change the time constants there. But the problem here is, what file is that?
