hey guys,

I left my lights on last night and this morning my battery was completly flat.. When trying to jump start it the car just clicks like crazy? any ideas how i can get it purring again?

Is there some special way to charging a skylines battery? ><

Did you try and jump start it using the terminals in the engine bay? or straight onto the battery in the boot?

I've jumped mine straight off the battery in the boot before I found out what the terminals in the engine bay were. Worked alright.

That clicking sound might be your starter motor. Are you jump starting off another car or a standalone battery?

Positive on positive. Negative on negative.

Hahaha.

I am connecting to the battery in the boot? is that where i should be connecting?

I was using my neighbours 83 ford laser to jump start ha-ha :P

Car was completely dead when i came out.. put jump leads on and i got dash lights back but when i tryed to turn it over it was clicking like a machine gun ;)

shouldn't matter where jumping from, but the points in the engine bay near the fuse box are easy to access. Make sure you have good size cables and a good connection on the clamps (this makes a massive difference). Failing that, the ford laser battery is probably crap and does not have enough cranking amps for the skyline. Call your local RACQ (not sure wat its called in WA) or find a bigger car/battery and try try again.

Make sure the laser has its engine running as well. You can try leaving the two batteries connected for a few mintues, the two batteries will try to equalize their level of charge, and the bigger skyline battery may have enough umph to crank but its not recommend to leave them connected longer than required.

The clicking sound is the starter motor using more amps than the battery can output, it starts to throw the solenoid out and turn the motor then it overloads the battery and turns off do to lack of voltage (voltage drops when you crank).

If you pop the bonnet, there's a black box on left side of the engine bay with jap writing all over it. It has a diagram of how to jump start from that box. You've got to pop the lid off to get to the terminals.

Try jumping from that one.

I was thinking the ford laser battery might be shot too, but it shouldn't matter if the laser is running while he's jump starting. The volts/amps should be boosted by the alternator. Revving the laser while jump starting can help with this.

Okay cheers guys, i thought there might have been something more to it.. like since 100 cars ive jumped start first time i thought cause its an import and the battery is in the boot there might have been a different way of starting it.. so yeah i got a battery charger ill take the battery out tonight and charge it over night and hopefully that should fix it ;)

While the alternator will help, I suspect a ford laser may have an alternator of like 80amps max, starter motors can draw like 400+ amps for the split second they crank, if the skyline's bat is dead flat and the ford's isn't in great condition the voltage will drop too quickly across the connection for the skyline to start. but meh getting techincal now - chuck the charger on there and it should be fine

Hahaha too true. I stand corrected ;)

+1 for the charger.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
