Well, since your gettin a new engine why not blow it up in style. Wet nitrous goes straight into intake manifold. Uses four hoses one for each inlet port. IF you choose to go this route, you will get more power. However with out a compatable fule pump and air intake, it will be useless. To burn this nitrous your gonna need more fuel and air to make a correct combustion. Dry nitrous plugs into your intake using one hose. Generaly gettin a 40 - 75 hp gain. (50 is ideal) you dont necesarily need a new fuel pump for this route, and if you getting a new engine, do dry. Its less work and still fun.
