Guys, my gtr has been sitting around for a while without being started, and i tried to start it today - no suprise, a flat battery

So i get the jumper leads from the other car and hook them up, the voltmeter shows almost half way, i turn it over and the starter motor is working, but the engine wont fire up

What would that be?

The manifold pressure keeps rising as it tries to start ive noticed.

I cant roll start it - so that is out of the question

Thanks in advance

Not enough voltage/current?

Turning over slow?

Try a better jumper battery, larger jumper leads or charge the battery overnight.

:P cheers :D

PS, you're a naughty boy, you should drive your GTR everyday.

It turns over at normal speed to start, then gets slower until theres nothing

Ive tried letting it charge for a while, but nothing

I also noticed the tacho goes spastic when the starter motor is trying to start the car

How would i charge it overnight?

Your also trying to push power from the jumper battery through the dead cells of the other battery. Overnight charging will be needed, also the cranking will be filling cylinders with fuel....not good for the plugs.

Steve, my car went flat while I was in Japan and there wasnt enough current left to jump it, or to register a charge using the trickle charger.

I got around it by connecting jumper leads at the back, connecting them to another car to get charge going in, then connected a charger to the terminals in the engine bay, which then registered charge.

Left it for 24 hours and hey presto :)

That said, it sounds like there might be another reason for your car failing to start :)

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
