Battery Relocation

[PORTS]

I have a couple of questions regarding moving my battery to

the rear of my 300ZX.

What type of battery should I use?

Does the battery box need to be ventilated to the outside or sealed?

Can I run a postive cable to the battery from the existing terminal?

Do I need to run an earth cable from the exsisting terminal to the battery,

or can I simply earth the battery at the rear and earth the exsisting terminal in the bay?

What cable type should I use?

I will fit an isolation switch, the 'red key' type, to the box.

Has anyone done this before, is there something that I missed?

The main reason for doing this is to use the space for an Oil Breather Tank

a swirl tank and maybe a surge tank.

i did this in 180sx, grab a battery off wrxhoon in the group buy section (if hes still doing em) they are a sealed lead battery which i then just popped in a non sealed battery box from supercheap auto, secured in the boot

run the existing earth from engine to chassis

run thick cable from battery + to existing terminal under bonnet

run earth from battery - to chassis in boot
