I had some ignition problems a few days back and called the nrma (it was after work and i had no tools on me ok).

After looking over the car we traced the problem to a loose lead (previous owner must have bent the contact out of shape so i could come loose.

Anyway thats no the point of all this.

One thing the mechanic mentioned to me is that as far as he knew skylines needed what was known as a high discharge battery or something of a similar name. he said that these batteries are vented and pointed out what looked to be a vent hole just to the left of the battery when viewed from the boot.

According to him the high power requirments mean that alot of gas is produced and if that is not correctly handled and left to build up a stray spark COULD (please note could not will) ignite those gas's hence the venting hole.

I've done a search and found a few comments about the right battery etc etc but no one has mentioned this.

Can anyone confirm or deny this.

I just got a new battery the other day and the mechanic didnt mention anything about having to get a high output battery or whatever. All he said was to take the black plastic box off the battery because it will cause it to overheat and die earlier.

Can't comment on your mechanic's comments re the high discharge stuff, however the battery area is vented to air because it is in the boot, any battery can produce gasses. As far as I know ...the Skyline power requirements are no more than any other modern car with fuel inj, power everything and air con etc.

I have read in at least three places that there is meant to be a maintenance-free battery with a vent hole that allows a tube to be fitted to it... This tube leads outside the car.

I watched one of my father's friends disconnect a charger from a battery before turning off the power point, I then watched him fly 30 feet through the air before hitting a brick wall, the impact killing him.

I have always worried about hydrogen gasses building up in my boot, with all the audio amps in the boot and smoking in the back seat. Hasn't happened yet but I keep worrying!

Next battery I get will either have this vent tube, or be enclosed in a box that's forcibly ventilated.

    • Got the motor out and torn down. I'll be dropping off the block Monday. Luckily the scoring on Cyl6 is much less pronounced then the pictures made it out to seem. It can barely be felt. If you pass your finger over it 10x you'll barely notice it. Hopefully by some chance it will only require a honing. I'm not in the mood to buy one size larger pistons or another block. Oddly enough my 6th cylinder with the scoring has extremely clean intake valves compared to my other 5 cylinders. I'm worried the scoring was caused by too much fuel or Water/Methanol washing the cylinder. I'll review some old logs to confirm.  This was also the first time I pull an engine with the transmission still attached. It went much better then expected. I was worried my CD009 wouldn't make it easy due to its sheer size but it was much easier this way. 
    • From the pictures I have when doing the job the flywheel is the same diameter, I don't think they're playing weird tricks like putting weights at the outer diameter to increase flywheel inertia or anything like that. The OEM flywheel is definitely heavier, but it's not a huge difference. Quoted weight savings of the clutch is 2 kg so I can't imagine the flywheel being lighter than ~7 kg. Kind of regret not weighing it before the clutch went into the car but as far as driveability goes I have no complaints.
    • HKS trigger kit should be very easy to integrate with a Link. It's a 36-2 crank trigger. Hard part is finding the motivation to take off the timing belt and everything on the front of the engine to install it. You also need to cut out a hole in the oil pump housing so the sensor can read the trigger wheel. Changing out the cam sensor for a 24 tooth setup is probably good enough but as others have mentioned depending on what underlying assumptions are changed it becomes more of a problem. Reading the crank state off of the cam is an abstraction that works in the general case, but if you have an edge case it makes less and less sense. There is a GTX2860 gen 2 that can take a compact 5 bolt housing so it's direct bolt on but I'm not 100% sure of what's involved. Peak compressor efficiency drops off a bit on these turbos vs -5s, 77% vs 73% but you get way, way wider region of operation. The -5s have a really strange surge line in their compressor map that is all over the place. If you think the hot side on the -5s aren't open enough you can try the Tomei T550B turbos which a local tuner seems to be happy with:
