'cause it's got to be the worst possible place to put a battery. not only do you lose valuable space in the already small boot, but you get a significant voltage loss through the cable that runs from one end of the car to the other, meaning that any problems with the charge in the battery is magnifyed.

Define significant? Has it been a problem for you?

I'd suggest trying to isolate what's wrong before you do that. If it's your battery- get a new one. Otherwise, you could simply upgrade the factory wiring to better quality cable, incl the grounding points too.

That being said, I don't know anyone who's moved their battery from the boot :P

The current location also makes it a lot easier for stereo installs, no need to run cables all the way to the back if the battery is already there.

You clearly have something wrong with your electrical system. Fix that rather than attmepting a bandaid, which probably won't fix it anyway.

If you have a look at the cable, it is a big mofo. Voltage drop is very minimal.

You say that boot is already small. What, do you plan on putting something up on the top battery shelf? hmmm, like maybe a pad of paper? or a book? maybe a pair of undies? coz you won't fit much up there

it has been a little bit of a problem for me. if i dont' drive a lot for a couple of weeks, the car does have a bit of trouble starting , but my battery is only about 18 months old and still holds a good charge so that's not my problem.

It is a basic rule of electronics that the longer and thicker the cable/wire coming from a battery, the higher resistance there is,and the higher the resistance, the more voltage is lost through that cable. And obviously the more voltage you lose, the less effective the starter motor will be to crank the engine into life. So instead of you being able to lose say 2 Volts of charge from your battery and still being able to start the car, with the battery so far away you may only be able to lose 1 Volt of charge. Obviously, the more you have hanging off the battery, the more drain you'll get. It's not a huge problem for me, but it does say something that 99% of cars have the battery under the bonnet within a meter of the starter.

Obviously it's not sounding like anyone considers this mod worthwhile

if its still the standard size batt, then id change it to a slightly larger one, which most cars have. cause it is a small battery.

ive left my car for over 2 weeks before and it had no problems at all starting up. so i think you might have a wireing problem there that would need looking at.

Just get a bigger battery, the original battery is to small. Even if you put it in the engine bay you will have the same problem

I measured the drop in voltage from the alternator and also at the back. I also did it when the car was off. The voltage drop was negligible. We're talking like 0.2V.

you obviously have an electrical problem like I said above. moving the batt won't fix it.

Could be a dead batt - just coz it's 18 months old doens't mean it's still good. might be too small.

could be bad ground - clean them and make sure they're tight.

could be dead alternator.

I've left my car for 1 month and it still started.

Thicker cable = less resistance . Thats the reason they use a thick cable .

sorry guys. i got my wires crossed (pun completely intended). thicker cable does = less resistance.

what kind of batteries do others use and where did u get them? regular sales points like beaurepairs and the like don't seem to know much about the skyline's battery. One guy put a regular lead acid battery in it instead of the sealed lead acid type and the thing leaked all in my boot!!! thankfully i fixed that really quick.

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
