Hi,

I have an R33. The battery is completely flat. It does this if I haven't driven for around 3 weeks. Normally I jump start it though this time I can't move the car to a place where the leads reach another car.

I have bought a battery charger. It says I need to take the battery out of the car. So far I am having a lot of difficulty in getting the battery out of the boot.

My questions:

1) Can I jump start the car from the battery or does it have to go through the points in the engine bay?

2) If I can't jump start from the boot and I have to get the battery out, are there any tricks associated with getting the battery out?

Thanks

hey mate

from memory the only thing really holding the battery in is the steel bracket above it, and the terminals themselves.

take the terminals off, and then unscrew the little nut which will be holding the plate down on top of the battery...the steel rod running down the front will come loose and you should be able to move it out of the way and slip the battery out :thumbsup:

Yes you can jump from the battery but it is better to do from the points in the engine bay as they are closer to the engine (less loss).

You can disconnect the battery and charge it while it is in the boot. BTW how big is the battery???...I had a huge battery in there (commo/falcon sized) and had no trouble removing it.

3 weeks without driving it would kill most batteries when the car has a good alarm and some extra electrical add ons..

mines a 550CCA battery, and it'll die (well not enough to crank the car) after about 2 weeks.

jump start from the battery direct is fine too.

the batteries in most modern cars will die if you don't drive them for approx 2 to 3 weeks... the onboard computer modules etc constantly draw a small supply from the battery, and over time that drains it.

I work in a roadside assistance callcentre as a job, and you would not believe how many people call up and wonder why their battery is dead after going on a 3 week holiday etc...

oh, and i'll tell you the same thing that i tell my customers...

if the vehicle is jumpstarted, you need to drive the vehicle for approximately 45 minutes at highway speeds (or at higher revs, anyway) to put some charge back into the battery.

Leaving it idling in your driveway will NOT charge the battery

i found out this out the hard way with my old car, thought i can start it up once every few days and let it sit idling for about 20 mins to re-charge battery, car started up for first few times than 2 weeks later, went to start, car just wont turn over.

don't know exactly how long it will last just sitting there, but i do know it would last a hell of a lot longer than if you left it connected :)

to prove this point, when i was doing some product training on one of the cars we cover the other night (Ferrari F430) they pointed out that this model has a battery isolator switch, which you turn to off if you go on holidays etc, this will stop the battery going flat while you're gone...

When my battery in the R33 went it took me over an hour to get it out and then at least another hour fitting the new battery as the new battery is a different size I had to adjust the brackets. Not to mention the time taken to unbolt the amp and subs in the boot to get to the battery.

Approx 3 hours, some blood, (knuckles and fingers from the damn bracket) sweat & tears (I was chopping onions earlier - nah just kidding) the new battery was finally in.

Good Luck :(

could be a short from dodgy wiring install...(Battery to boot relocation) If it stilll happens after your new batt may be an idea

R33 have battery in boot as standard.

Wet Standard (Sb/Sb) - High self-discharge rate (depending on the temperature, up to 50%-60% per month)

Wet "Maintenance Free" (Ca/Ca) - Up to 400% less self discharge

Sealed Absorbed Glass Mat (AGM) VRLA - Lower self-discharge rate (typically 1%-2% per month)

i'm looking up details for a new battery myself.

same battery that has been in my car since i got it 2.5 yrs ago. doesnt use the breather tube, has filler caps, to is illegal inside trunk.

thing plays up every 6months or so. leaving the headlights on for 15-20 saps enough to stop it cranking.

dont rely on racv, 60-90mins can turn into 2hrs++ as i found out.

racv dude puts negative clamp on the engine. shorter distance. dunno if it makes much difference. only other reason ive read, it to stop arcing near the battery in normal cars, as they battery can leak gas.

not looking forward to replacing cable clamps or battery cage =(

    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.  
    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
    • Yep that is correct. It allows you to adjust the short throw range from what I can tell
    • Car has been running great, I've put about 300km's of break in time on it. First thing that stands out with properly sealing rings is no more noticeable crankcase smell coming out of my catch can. This may seem insignificant, but the constant smell while driving around was infuriating. It's also nice to see my oil level remain stable. Two new issues have developed that I only noticed this weekend though. There's a very noticeable driveline vibration past 100kmh. I only noticed it now as I've been babying it under 100kmh in the backroads. This comes as no surprise as I'm running a one-piece shaft, and I paid zero attention to my driveshaft angle when I put everything back in. I also have a fair bit of voltage drop on hot starts. The starter audibly is forcing. No issues on cold start though. I must not have removed all the paint under my main block ground during assembly. I'll try and take care of both those issues this week once the kids are asleep.  I also received all the parts I was missing for my direct port setup. I will hopefully have pictures of that up soon. I'm hoping to get back on the dyno the week of June 30th as I'll be on vacation. I'm confident I should be able to make north of 500rwkw on pump gas and WMI. I'll go back again later this summer with E98, but I want to confirm my ethanol content sensor is working properly first. I've never seen it read anything but 11%. This makes sense for our 10% ethanol content pump gas here, but I would expect the occasional movement between fill ups.
