I have a buddy that works at a battery store and gets a small discount on the batteries. The battery I thought you guys would need is the Oddessey PC680. It is the smallest battery that i have found that runs the rx7. I have one in my Fd and it starts and runs perfect with stereo and ac running. Below is a pic of it kinda ghetto rigged in my car right now. But this should give you the size. I can get them out for 125 shipped. No tax unless your located in arizona. They weigh about 8-12 lbs... I would guess. They will almost fit anywhere. Pm me here or email me at pstonssuk@yahoo.com If you have any questions feel free to ask.

Had one in our FD. One word of advice.. dont let it sit more than 3 days or you'll need a battery booster. I recommend the PC925 the same battery they use in the Busch cars, we have fabricated a kit that allows you to mount this in the stock position.... ***with an FMIC and upright radiator*** PM me for details

wow that battery is rigged up.............time to bolt that sucker down! you are gonna lose some fins on your fans!

Not sure how much shipping would be but I'm fairly certain www.batterymart.com has them for around $85.
