before pulling the starter motor out:

Check your battery voltage, both just sitting with everything off (Should be about 12.6V or so) and then during cranking (shouldnt drop below 9v from memory, even 9v I think is getting to low)

if this checks out, put the car in gear and roll it back or forward a bit (the gear for the starter might be jammed against the ring gear.

But if this fails then I'd say it would be the starter motor as suggested

sounds like mine when my battery dead, the battery got not enough power to start the car. If jump is working then your car can still use the battery for a few days/weeks?

Jump means you taking other's car battery power to start your car and then you still use your underpower battery, the car do charge the battery but it won't last long anymore. It will die soon so replace the battery asap.

Not true, my battery has gone flat about 3 times in the last year and is still fine.

Only a cheap compliance battery as well....

yeah same..get a proper (plug in the wall) battery charger, bunnings has them cheaper than auto stores, I got a fairly decent one with an engine start option on it as well for about 60-80$..

my battery has gone flat numerous times..but after a good overnight charge its good as new..

If battery keeps dying, won't it be an alternator problem?..

Or is it because of the cold weather? I know that short drives + loud music w/ sub can drain the battery before the alternator can charge it

Ohhhhhhhhhhhhhh, maybe that's what happened to me!!! i had pretty good sound system and maybe the battery went flat before the alternator charge it!! That is why the battery keep going flat and die. And short drive yes :(

That makes perfect sense, I recently moved within 15mins of my work and only drive the car there & back at night.. with the sub going nuts lol..

You need to check that you don't have a drain somewhere in my car. My old car had a dodgy earth and the glovebox light was shorting to ground (not through the switch) and staying on

This over night was draining the battery

Simple check I guess you could do to eliminate a failing battery is unplug it (negative first) and leave the car sit over night and plug the battery back in. If all is well then it's a problem with the wiring. If not it could be your alternator or your battery

RAA guy who came out to jump my car last night noticed my boot light wasn't turning off when closing the boot. We couldnt find the switch so thought it must have been in the lock.

Anyway, pulled the globe out yesterday and guess what? Car started first go tonight ^_^

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Second time Skyline owner (R33 GTS-T and now a V36 370GT)

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
