Hey Guys,

Will be putting a new system in my R33 pretty soon and i'm not sure if my battery will be up to scratch. I'm still running the original Japanese battery, which appears it may be on its way out after spending months sitting doing nothing. It's ok and the car starts, but as I said, its the original... :uh-huh:

I'll be adding 2 amps to my system. a Clarion 400W and a Sony 222W.

I was wondering if anyone could offer advice on whether I should change my battery and if so, what type/brand of battery should I use to effectively run this system?

My stock battery seems to go fine running two amps, even when the volume is way up and I have headlights on.

If you have any doubts, install a capacitor (about $150-$300) for your amps.

But I reckon you'll be fine. I'd only change if you're not happy with the results...

-I think the oddyssey 1000 battery put out about 380 CCA.

They are a good battery just dont let them go flat, ie rarely run your system without the engine runing, as they die when they are drained of most of there power. They dont behave like a normal lead acid battery.

That oddyssey sounds like a monster battery, but also a monster price too...

I reckon any standard heavy duty battery of the right rating will do the trick... people run 2 amps + much more off the one battery with no probs.

Amps draw less and less power these days as well to output the same amount of wattage. More efficient components.

those amps wouldnt be pulling too much electrical draw from your system. you should be fine

just get a nice healthy 4guage power for red and black

and also upgrade your battery's ground to 4guage and also your alternator wiring to 4guage and the stocker batter will cope a heck of a lot better.

that done, your set to go

4guage into a distribution block and then 2x8 guage to the amps and your all done.

good luck

in any serious sretu i wouldnt go past and OPTIMA yellowtop deep cycle battery

950CCA 95A regular cycle and its a 95AH cell

where as the highest oddesey has to offer is a 65ah cell and the standard battery in skilines id a 45ah cell

if doing a big install the ah rating is more iportant than the CCA

and a high regular cycle can only help things along

dont forget a 100w RMS X2 amp will draw about 300W - 400W from your battery which works out to be about 30 A

im running 600w worth of amp and it draws almost 1000w from my electrical system

im using and optima yellow top and i get no dimming of the lights with all healights on

bottom line is the bigger the battery the better

I'm suprised nobody has mentioned alternators at all in this discussion.

How did you go fitting the Optima in the Skyline?

I am looking at a new battery for my 33 GTR as the factory one is tiny and rooted. I haven't taken all the bracing out yet so haven't sized up what I've got to work with but the options for the battery seem very limited by the size of battery you can fit in.

At the moment I am thinking of goind with the Odyssey 1000, but would much prefer the Optima/Exide if at all possible.

there is plenty of room in the back of the R33 GTR for a replacement battery, i am running the odyssey 1000 in mine, just had to make up a custom bracket to hold it down, and a little L bracket to make sure the battery doesn't move.. there is plenty of height and width available..

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
