Dude - if you are pulling 1.3 to 1.4g lateral G and you have not done anything about avoiding oil surge, this is what you will see.

The top-end of the engine looks like it has starved of oil, so my guess is that you suffered oil surge ... if that is the case, then the bearings (main and big-end) need to be checked as well .. IMHO best to strip the block - look at everything and rebuild.

I'm surprised that anyone would think that Nissan would cover engine failure during a Time Attack run as a warrantable situation as (in Australia at least) participation in organsied motor sport events invalidates the warranty.

That's why I have taken quite a lot of time to look after the oiling system in my car t make sure it does not suffer these sort of cnsequecnes.

That said, HR heads, hi-comp pistons and BIG cams is clearly the way to go now !!!

Good luck ....
