i was looking into many cars b4 purchasing my Z .. the Evo being 1 of them .. using a mini battery is a common mod for them i was wondering why we dont consider this? good amount of weight savings i would think?? i know they also use it to free up engine space but do we need more power from our batteries?? heres a ebay link to what im talking about look for the 1 with auto terminals.. http://search.ebay.com/odyssey-680mj_W0QQfkrZ1QQfromZR8
