josh how'd you go from a lightning to a d series? do a b series swap or somethin man... lol

that said, i don't know how much a stock d series can take, but things like colder plugs, say 2 degrees of retard, and if you're really worried a bigger fuel pump are things you can do to help make sure it won't break down on you. and 93octane is a must with nitrous. IMO a wet kit is better because it decreases the chances of running lean & detonating, but a lot of people like dry kits for single nozzle systems
