looking for something on this topic.

but have come up with nothing at all.

where is the best place to run the wire through from the engine bay,

and for racing purposes, do i need to insulate that wire some more through the fire wall etc?

you can run it though the passenger side of the fire wall but will need to take the inner guard out, or the easier way it to run it under the car along the fuel line and come up though a hole under the spare tyre, takes no time and don't have to take any panels off :thumbsup:

1. Take the wheel off and some of the screws for the plastic guard

2. push a screwdriver through the hugely apparent rubber grommet from the front into the car.

This is the drivers side and i don't know if its the same the otherside, but then you will have to run the cable across the engine somewhere and thats bad for reasons of heat+plastic.

I wrapped most of the cable from the battery in black electrical tape (because its illegal to be red, or something stupid)

I used 2 guage for power, but 8 guage would be perfect. I have been told 2 guage is a bit of overkill by some people and that 0 guage is only way to go for power by others. :. I don't think there is a 4 guage....I could be wrong but I have never seen any.

A lot of cars run a battery in the boot (wieght distribution). 0 gauge is huge over kill, it would be approx. 2-3cm thick and good luck getting it through any where let alone around any tight fitting bends or trims! Any way, if you haven't noticed the cars wiring (positive and negative) on an R32 is 8 gauge at best to the terminals. 4 gauge is ideal - large enough to not drop voltage but appliable and the correct size for aftermarket battery terminals. And 4 gauge is what most factory cars run for there main power cables (batteries, starter motors etc.).

Running it under the car is illegal and emencely dangerous if the wire was to be exposed (especially in an accident!)

As previously mentioned, your battery is on the drivers side so run it through where the picture showed you!

Don't be lazy and pull your seats out, lift you carpet up and lay the wire correctly as the main wiring loom to the back is there so it's easy to follow all the way into the boot

I would go the extra mile to and take the chance to improve your cars electrical capability and replace your earths and add a few new ones with black 4 gauge wire as all your motor electronics earth through your motor to earth lead to chassis so if you have a better connection and more of them you may be surprised at the difference. Thats what those earth kits are for!

To be honest with you, I'm going to be doing this in the near future too and haven't looked at how I'm going to mount my battery and case in the boot so if you do yours, post pics or tutorial!

Hope that helps :P

hmm thanks for the info ellie

i rang complete carsound today and asked for their opinion (i've bought stuff off them before) and they said to use "00" gauge cable. they can get it for me for roughly $25/m.

ripping the HICAS out soon, so i may aswell do the wiring right also

I recently relocated my battery into the boot of my car. Used 2 gauge cable, ran both the positive and negative cables under the car (wrapped in 2 cable conduit tubes). Ran along the chassis rails near the brake lines, making sure i tucked the cnduit under as close as possible to the body, cable-tie-ing every 10cm or so.

bought an approved battery box from peps ( repco, supercheap etc etc will have them) and finished it off by using som gold plated terminal mounts.

You dont need to run a neg cable to the front of the car. All you need is positive to the front and the neg to the body in the boot somewhere.

You beed to vent the box outside, unless you have a sealed battery.

Hey fellas, im in the process of doing this mod in my GTR. But i cant for the life of me find any thick enough electrical wire to run from the engine to the battery in the boot.

Im looking for 4Gauge, but was just hopeing someone could throw me a couple of shops or numbers i should try, im in Sydney?

Thanks a lot guys...

If anyone's wondering how long a cable you need, its 5.2m. this will be sufficient to go from the fron where the battery originally was, under the front guard following the other cable, and under the carpet into the left hand side of the boot plus giving a little bit extra.

i've got mine on the left as i'll be putting the surge tank and pumps on the right :wave:

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
