The idea of todays nitrous systems is that you don't burn up your engine. but if you get the mixture rong....example, lean fuel mixture and a lot of nitrous. You will toast something like valves, piston rings, head gaskets, ect. It would be highly recomended to get a checkup on your engine before you add a nitrous oxide system. By the way,,,,, MB engines are very strong. didn't you know?
good luck!
