Summit Racing has some good kits w/battery box and cables. The battery must be bolted down securely.Also the positive cable must be routed carefully and protected from damage. Do this right or you can set your car on fire. I used a 500amp fuse and a cut-off switch.
The car we did this on is Golfer17's.I don't think there are any pics of the battery yet. sorry.

you need a kill switch or fail .....!

500 Amps is WAY too much, you'd never be able to blow that (you'd have a fire first, completely negating the benefit of having a fuse).

I pulled the plastic out of my coupe, and used some L-brackets to go up over teh top of the battery, and hold it on the sides (while being bolted into the trunk floor and the body panel running vertically next to the taillight.

I recommend using a fuse rated somewhere around what your alternator puts out - for our cars, 100A is fine.

I ran a ground to the trunk (cleaned it out/made a good ground), ran a 4ga cable (fused in the first 6") to the passenger side footwell by the ECU, then ran a power distribution block to power the starter and fuse box. The ground that used to go to the battery was grounded to the frame rail.

most tech inspections look for a kill switch on a relocated battery

yea i have all the parts to do the trunk mount; circuit breaker, kill switch, box, bracket, 0 gauge wire. im just not sure where in the trunk i can mount it, since the fuel tank is right there.

I mounted mine in the back passenger side corner. right by the tailight! with 2 guage wire though. 0 g. is going to be a bitch to try and move though the car! if you drill through the trunk to mount it. BE VERY CAREFUL WHEN DRILLING YOUR HOLES! you can drill the 3 outside corners fine but the one towerds the center of the car will only be about 1/4 of an inch of room until you drill into your gas tank.

mounted mine at the same spot but w/optima. kill switch is right behind the pass door. welded 2 L brackets on the floor,get a battery tie down kit and hook it to the L brackets.

I think 0g is a little over kill, I used to have it in my car and switch to 4g. it works just fine and weighs half as much.
