Spares are oil for defo, i would use a 10 50 oil as its better for the long distances :) how to keep your turbo from over heating, let it warm up to optimum temperatures before driving hard, and dont stay on boost for long periods of time, gauges gauges and guages, oil temp, pressure, boost, water are all essential for long distances this way you can monitor everything, take some spare vaccum hose just incase any perise on the way or replace any that look abit shady :) do a full oil change and coolant flush before you go as well :) take some fuel addictive as im sure Morocco has a lower ron than ours :)
