Lol, you need the modules and what not, for the glow plugs, if you're injector pump, injectors and all of the lines are there, then you will need to completely clean out the fuel line from the tank to the engine bay and you need to clean out the tank. you need a fuel/water separator and fuel filter as close to the injector pump as possible. sure you can do over 75mph with the ld28, but it will take you a while. You really need to download the diesel maxima's FSM and do a little searching on google.
