ok im a bit weak on awd systems so i have a question. i heard a lot about really high hp skylines around the world like 600+ hp. i was wonderind at that kind of hp would you have to mess with the transfer case at all? like is the skyline transfer cases chain driven and if so what would be done to convert it? this is a knowlage question i ran a search but could not find a thing. im just wanting to know what these people did. thanks for the help
