It's recommended that you use 1/0. It's not that expensive. http://www.knukonceptz.com

If you're going to go through the trouble of doing this mod, do it right the first time and use 1/0.

1\0!!! no reason to go small when its VERY inexpensive to go large, and have lots of room for expansion (no need to rip it all out incase you decided to get bigger, and most do)

1\0!!!! at LEAST 2awg!
