You shouldn't have to swap anything else as the current is just a formula for the voltage and resistance. What you'd need is to upgrade your wiring, especially ground wires. The older and crustier the connections and wires are the higher the resistance is, the higher the amps get and the hotter the wires get, bad case would be hot enough to start a fire!

Ill get a brand new one. will I have to get anything upgraded as well? like the volt regulator. Ill probably be going up to around 40 or 50 amps.
