Help me add 100 hp to a magnum 5.9 on a super tight budget

I'd go with nitrous as well, a 125 or 150 shot kit, sometimes, they pop up used, for a decent price. You'll have to add an electric fuel pump,and lines to supply the added fuel needed. For what it's worth, I wouldn't recommend driving the car you are racing, race, and drive home in it, as a sole means to get there and back. You might be best to rent a truck and trailer, be ause you just never know what could happen. Sure people do it, and you should be able to make an eight hour trip and have fun without a break down; but this will be racing. Expect the unexpected.
