    Allow approx $300 in parts. More if you want a Moroso box (Highly recommended, check ebay)
    Suggest 2g cable.
    Isolation switch. Mine is on the earth side.
    Box must be ventilated to outside of the car and sealed.
    Battery must be securely bolted down.
    Highly recommend a sealed battery. I had a normal lead acid unit leak into the box.
    The earth cable must be to something solid steel on the car chassis and remove all paint from the contact surface.
    The power lead must be out of harms way. You don't want it being pinched or the insulation damaged.

    I've run the power lead to a terminal post in the engine bay. From there I connected the main fuse box and starter to it.

    No idea, Suggest take a tape measure to the length of the car and add a bit for just in case.
    All my cable ends are crimped with eyelets not screw fittings. Gives a better connection.
    I got all the gear from an auto elec then ran the cables as required, went back and he terminated the ends and we moved the battery. Makes for a quick changeover.

    $300 is excessive... I have everything needed for my battery relocation.... actually, more than is required.... I'm running 0guage wire from the battery to the engine bay, then 2guage through the engine bay. I purchased new battery clamps, power distribution blocks, 150amp fused links (platinum plated for negative gold plated for positive) 11m of 0guage wire and the battery box... So far, at a cost of ~$120... I went to the cable recyclers in Adelaide, so rather than the 0guage costing $200, it only cost $50... I only so much wire, because I'm running the negative cable through the car, and grounding to the body at several points, this is so I can run a ground directly to the engine from the battery.

    Moral being, shop around, buy second hand cable, and get stuff off ebay....

    Just my 2c.

    I've got 4m 2 gauge wire from jaycar for 48 (guy in the store did me a favor shaved 2.6/m), 20bux for a battery box off ebay, now still need to buy a battery terminal, distribution block, kill switch, ring terminals, I have about 3m 4gauge wire from the 4g, may need another meter or 2, and I'm using old 8gauge amp wires to upgrade the grounds, hopefully can get everything setup for under 150
