Well to compare - driving home last night my oil pressure was sitting on zero for about 20 mins and under throtle it would just go above one. At start up it sits on 4 till warm. Checked the oil the next morning and its still right on full which was serviced with the same motul turbo light 1,500kms ago. The cars behaviour has not changed at all...stupid guages. 98% Compression ratio result on all four pistons was tested 3 months ago. Will post again if my engine blows up.

Well, most of the things you just listed as "checked" have nothing to do with oil pressure (unless you ran out of oil). Putting more oil in it will not increase pressure (although thicker oil will), and cylinder pressure has zero to do with it also. With 0 pressure at hot idle, and just over 1 bar after some throttle, I hope for your sake it is the gage.

Defi gauges read kg/cm^2 yeah?

When cold and a little bit of revving it hits just under 10, shown by peak hold option.

On hot idle its a touch above 2.

Built engine, 10w60 Castrol Edge Sport as directed by top notch engine builder. No dramas!

I wouldnt stress considering you know nothing about the motor. You cannot compare anyone elses motor to yours. Unless yours was nissan standard. Nor can anybody quote a figure from a factory guage!!!!

Yeah, i hope so too. Its hard to beleive the guage because I have this crazy relocation system with a cooler, pump extra lines to the head and the filter for some reason sits at the front just inside the bumper bar. I have to get someone noligable to have a good look at the car, coz honestly, i have no idea. P.S. Clicked your link - beautiful car. Mine is black too with the same steering wheel.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      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.
