IF you don't have to move it, Don't. Its really not going to help you with weight bias, and unless you need the open space for turbo components I would simply get a smaller battery. The Braile auto, Oddysey, and similar ones are nice, deka makes an "off brand" that is the same battery. You and even buy them local at Batteries Plus. Google is your friend. There is a TON of information out there on how to do this and the pros and cons of both ways.
