The 12v will make your life much easier. Also, it is more capable of producing high horsepower numbers if thats something you guys are looking for. As for internals, you shouldn't really need internal parts until you start getting up in the higher hp levels. There are lots of different options for things like injectors, and fuel pump mods depending on which way you go. I'd recommend the 12v because its a more capable more reliable engine. The main benefit to the 24v is being able to turn the box down for towing.
