I'm going to relocate the battery to the boot and I'm wondering if anyone has used kits for this type of thing or do you all just go your own route and source parts you need.

I'm not auto electrician so I'm not fully versed on what parts are required.

As I see it, some heavy gauge cable to connect the battery to the engine bay terminals, I'd imagine some sort of heavy duty fuse for safety and I'd like to put an isolation switch in to stop the battery being slowly drained while the car sits as it's not driven regularly.

What's going to be the best way to go about this. I'm all for DIY just not sure what's required.

We are looking at doing this in our R32 with the cable etc from a R33. This can be easily obtained from a R33 wreck and it comes with all of the protective covering from the R33.

I've just finished doing this. Sprint Auto have metal battery trays that you put in the bottom of the battery box for $15.00.

The cable is only $7.50 / Metre.

I used spiral wrap around the cable to just it extra protection.

I did this on my S15 and in the process of doing the same on my s14 now.

Try to use a dry cell if you are mounting in the boot or inside the cabin.

If you want to do it yourself just measure up the length of cable required by running a piece of string or rope along the required path and cut it/mark it at the required length.

Go to an auto electrician or a welding shop to buy the cable depending on what gauge you need for your application.

Use a fuse as close to the battery as possible.

Run the same size earth from the battery to the body as the power cable and make sure you get a good contact.

A battery isolator switch is a good idea if you are not going to be driving the car regularly and I also got myself a battery charger that I can just leave on when I'm not driving the car.

This time I purchased a kit as I want everything to look a bit neater this time but it wasn't cheap.

Cheers

Yeah, the conduit does make it look a lot neater. And if you get carried away and want to wrap it in black elec tape it almost looks factory.

Not sure about the boxes - I am looking at these fused +ve terminals http://www.projecta.com.au/catalogue/cid/35/asset_id/84, then a key type kill switch for the cabin, and I need to run an external pull near the windscreen as well. Going to run an earth in the boot and one to the bay - that should have me covered.

So the general consensus is:

- 250A fuse on the +ve off the battery

- 00AWG (2/0) guage for +ve to the bay

- 4AWG earth in the boot and to the bay

Can any autoleccy's confirm this sounds right?

An auto sparky told me to run the earth lead from the battery to the front firewall, then from the front firewall to the engine block. This is if you have an alloy radiator, otherwise your cooling system can have some residual current flowing through it, causing electrolysis of the alloy rad.

Also if you have a normal wet battery in the boot, you either have to have it in a sealed, vented box (not a marine type battery box) or you need to have a liquid proof firewall between the boot and cabin (CAMS and DOT regulation). If you mount a wet cell battery in the cabin, then it must be in a proper sealed, plumbed battery box.

I've got all my gear together now and am embarking on the job but I was wondering, do I need a blue trianlge sticker on the car now? It's only club level and still street reg'd.

I grabbed an isolator that will allow remote pull to swich off but won't be connecting the remote feature straight away. Will just leave the key in the isolator.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      Back in January, I noticed my car felt noticeably weak. I had the injectors cleaned, which seemed to solve the problem -- until now. Recently, the car suddenly lost power again while driving. Suspecting the injectors, I brought it to the mechanic. He recommended replacing them entirely, saying the current ones were getting unreliable and fiddly to work with. I could not find a direct replacement for my current injectors. The closest match I found were 440cc injectors. This led me to look into the possibility of upgrading -- and of course, that would mean remapping the ECU. From my research I found: The OEM Part numbers are 16600-72L20 and 16600-72L21 Both the RB20DE and RB20DET use the same 270cc injectors. There are much better options out there over the old OEM injectors. Nistune could be a viable tuning option. While the RB20DE isn’t explicitly listed on their site, the ECU is essentially the same as the GTS-T version - just with a different map. The ECU code on mine is listed as supported. One concern is finding a tuner who works with Nistune. Aftermarket ECU like Haltech and Link, but this would be the most expensive choice (and possibly overkill for a mostly stock RB20DE) I admit that I am very new to the tuning scene and would appreciate any insight or recommendations regarding this.   These are some SAU links where I got some of my information from for reference: https://www.sau.com.au/forums/topic/380324-rb20de-injectors/ https://www.sau.com.au/forums/topic/477396-factory-270cc-injectors/

      Anyone know this frontpipe?

      The inspectors are not forensic by any means but if you forge your documents and/or badgings on vehicle parts and are found out, the consequences are just far bigger than if you just run illegal parts. And their job quite literally is to cross reference what parts you got installed and what your papers say you got. Something as silly as your suspension being 1mm too low will fail you. Nonetheless I asked if someone knew the damn pipe and I certainly did not ask for smartassery or underhanded comments, no idea why you need to be told this. Great way to waste both our time.

      As useful as you explaining what forgery is... But then again, I wasn't aware your inspectors were also forensic experts and inspect nameplates on each component to confirm everything is original. They must inspect roughly 3 cars a year at that rate. You're right though, my comment doesn't help you in anyway, so I'll go talk to my wall now. Cheers.

      Say that to the guy that is going to fail your inspection or tow your car for illegal exhaust modifications. If you have anything else useful to say, please go tell your wall.
