I dont think you could really call a GTR a sleeper.

I would have called my 4 door a sleeper. It was often considered to be just another 4 door sedan (lots of people don't even realise nissan made a 4 door skyline) but had all the right bits where it counted. It wasnt untill I applied the brakes (after beating them off the line) that they realised it was a skyline.

sleepers are cars that look normal on the outside but are packing extreme heat under the bonnet. The best examples of sleepers are the cars that have a reputation for being slow and/or a grandpas car (things like old toyota cressidas, old nissan bluebirds etc) but have had an engine conversion to a big power engine.

a sleeper...

Volvo station wagon. (no expectation of 'go' from one of these).

Worked 5L V8 , forgies, roller rockers , head work, manifold, cam, Tricked up auto with shift kit and B&M quickshifter, 3.25 Dana 30 LSD diff.. blah blah blah.

There is a silver/blue volvo sedan over here that has a very warm chev in it and it runs 12.2 second quater miles, in street trim.

what does the station wagon pull out in a quarter??

It might do a high 13 all things being equal on a good day. At the moment it is in a reasonable state of tune, I spent all last week fixing things on it. For the previous six months it was without the use of the secondaries on the carby (the wife and kids drive around in it so they didn't mind).

I have a 294 duration big lift cam sitting in the shed at the moment that along with a 2000-2500rpm or so high stall and some mucking around might get it into low 13's. But... I shouldn't go doing things like that when I have an R32 GTR to spend money on.

    • FWIW, I've aerated oil, and cams snapped. You can figure out the rest 🥲
    • Depending on the hose, sometimes engine out is the easiest option  
    • Get an inspection camera up there. 
    • Yeah, but look at the margin in viscosity between the 40 and the 60 at 125°C. It is not very large. It is the difference between 7 and 11 cP. Compare that to the viscosity at only 90°C. The viscosity axis is logarithmic. The numbers at 90 are ~15 and ~35. That is about half for the 40 wt oil and <half for the 60. You give up viscosity EXPONENTIALLY as temperature rises. Literally. That is why I declare thicker oil to be a bandaid, and a brittle one at that. Keep the oil temperature under about 110°C and you should be better off.   Having said all of that, which remains true as a general principle, if you have indeed lost enough oil from the sump that the pump was seeing slightly aerated oil, then all bets are off. That would of course cause oil pressure to collapse. And 35 psi is a collapse given what you were doing to the engine. Especially if the oil was that hot and viscosity had also collapsed. And I would put money on rod or main bearings being the source of the any noise that registered as knock. Hydraulic lifters should be able to cope with the hotter oil and lower pressure enough to prvent too much high frequency noise, although I am willing to admit it could be the source.
