So i have done some reading about doing "the big 3", Anyways, I got my Celica a few weeks ago the wiring was already done. I did not realize the previous owner had already attempted the big 3. Well he did finish, BUT the wire is 16 gauge. So that defeats the purpose of doing it does it not? Should i just replace the wires with 2G wire or 4? And what exactly are the benefits of doing this, just more power?

Use 4-2gauge wire. A GOOD, quality wire is welding cable. 1/0 is cheap and will be more than enough even for an upgraded alternator. A fuse holder, about 10-12 feet of wire, and 100 amp ANL fuse and good,tight crimp connections.




Wire #1: Alternator+ to Battery+ (FUSED)
Wire #2: Battery- to Chassis
Wire #3: Engine to Chassis

The idea of doing this is to have free-flowing current. The bigger the wire, the better. 8 gauge is small. Factory is around 8 gauge so you'd just be replacing the factory wiring.

Remember current, like fluids, flow down the path of least resistance. If you have an old, corroded 8 gauge wire and put in new 8 gauge, most likely it'll flow down the new one. It won't spread throughout both wires, it'll just travel down one. So use a minimum of 4 AWG.

Knukonceptz has the best wire for the money. (audio wire)

Welding cable is the best, and it's got a strong jacket made to withstand heat and abrasives, overall a harsh environment.
