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

What is your budget?
Does it have to be N/A?

I think it needs to stay NA. It's going to be a driver and stone simple is the goal. I'm thinking I'd really like to stay under a grand to make this beat him

His car has every advantage except the amount of cylinders the engine has.
I’d never use anything “Assault.”

meh ,came with the car. My suspicion is one chinese knock off is probably not much different than another chinese knock off but I guess we will find out.

Do you have one of your brothers timeslips?

he never raced it.

Have you raced him yet? Some of them loaded genesis can be well over 4000lbs. Perhaps look at power to rate ratio to see how you stack up?

His is a coupe which the all knowing Google puts at about 3800. If Google is correct my car is a few hundred lighter but I'm about a hundred pounds heavier than him soooo
