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.

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:

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......

      I get into huffs with people when I suggest the MX5 looks so much better as a coupe than it does as convertible. Pretty sure I don't prefer the convertible version of anything. Good job on the hardtop! The next buyer will appreciate.

      IMO wrap does have its uses, but like you said, quality wrap, and professional installation, would probably cost want a quality paint job does, but, the paint, if maintained, is basically for life, and much easier to touch up if required  In other news: it's pissing down here, with thunder, lightning and only some small hail "at this stage", luckily all "my" cars are undercover  I've also been contacted by a guy in Newcastle about the SS, he said he will come down next weekend for a look, we'll see how that transpires I guess 🫰
