i have a used nitrous express kit that is 20-75 hp shot. will come with carbs already set up. daul pingle valve. fuel pump, battery, tank. nozzles, solenoids, brand new never opend motion pro cable, brand new k&n filters and outer wears, and brand new bullseyes intakes. i may have left something out but for sure it will come with all these parts. everything i have listed costs around $1100 - $1500 new depending on where you get your stuff. i am looking for a complete big bore kit or maybe some power valve cylinders.
