ok your not against what i said, is still dont find it coincidental that he has more then likely spun a bearing after a 0-180km run

Im sure when nissan did their tests on the RB26 it wasnt on an engine with 355rwhp,

the stock sump works fine for a stock car but when the engine is making more then 100hp over factory specs then reliablity starts to decrease and things do go wrong

anyway... i know of a few people that run 6L in their GTR's...GTRSEAN has figured it out that 6L is low enough to prevent the crank whipping through the oil in the sump

So, if the oil is not in the sump, where is it?

How the could the head flood with oil? I would have though it was obvious that this would happen before the sump is empty.

You can still have some oil in the sump and not have it picked up...

For example, the engine is operating at high rpm like in this instance.. some of the oil in the head and is unable to drain back quick enough

The oil that is left in the sump is subject to G forces and is being pushed up against the rear of the sump..

It is entirely possible for the pickup to not be getting enough oil to supply the engine

I always run 6L for safety.

GTR Joey is right, and it only takes the pickup a second to miss oil and damage is done.

To the OP, can u please write that u were on a racetrack or private road because u were ;)

any -ve's on running extra litre of oil?

commie u mean ? imo u cant hurt anythin by adding a max of 1 litre extra oil to an engine. if u are doin a track day or drifting u need to keep the pickup submerged at all times. xr6 t's hold 7l stock so ive never over filled mine.

Similar way that i spun a bearing. Whilst giving it a spirited run, the fitting that came off the block for the oil cooler and relocator failed.. Causing me to lose a substantial amount of oil..

Even though this is an extreme example of oil starvation, it still gives merit to the importance of oil control and supply.

OP, search for "oil control in rb's" .. Will give you good insight to the nature, and resolution, of the problem which you faced.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.

      Strange issue RB25DET wont start

      Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.

      The fact that US/JDM plates actually fit the skyline bumpers properly is a big, big thing for me as they are the correct dimensions. Annoyingly you can't opt for a normal plate (or plate combination) in that size. You have to make up your own one, and at that point you'd still know it wasn't randomly assigned.

      Well, really, that's any ECU, because it's not so much the ECU that the tuner connects to, but a laptop that's connected to the ECU. You have to have the tuning software installed locally. The "remote" part is essentially just remote desktop (RDP) or VNC type access. Nevertheless, if you're looking to upgrade, then you're immediately in the Haltech/Link territory, both of which can be done by any number of competent tuners here in Oz. But without a dyno, you'll definitely also need a wideband O2 sensor fitted, and you'll probably be relying on "auto" tuning a bit, where you drive it around under various loads and then apply the corrections that the ECU learns (basically applying the fuel trims that the ECU has to do to correct the mixtures). Tuning the timing is a little harder. It can be difficult to trust the old OEM knock sensors on RBs, so it is definitely best to have someone who knows what they're listening for, with knock ears (a piezo microphone connected to the engine, and and little amp and headphones so the listener can hear the angry men with hammers who live in the engine). That is more difficult to do remotely, and I suspect the only sane way is to be quite conservative on timing. But that's OK. You're probably waaaaay better off with conservative timing where you are. What is the fuel situation? 98RON available? Or low grade jungle juice?

      I see your point, I didn't think too deep into it, was purely focused on the price. There's no bad blood between myself and GSM, they acknowledged the price was cheaper else where and at the time couldn't match it.
