After installing an Oil cooler I want to protect the engine when starting by supplying the turbos and all other components with oil before starting.

So I purchased an Accusump form Canton Racing

It choosed the smalest 1QT accusump and the Electric valve #24-271X

After 8 Month of use I am absolutely thrilled. It works absolutely perfect. Before starting, switch the ignition on for 5 seconds until the oil control lamp is off. I was initially concerned that the pressure in the memory would decrease over a long period of time as I do not drive the GTR very often, but that is not the case. Even after 5 weeks, the pressure in the accumulator is the same as on the first day. For safety, there is an oil pressure switch on the valve that opens the valve when the pressure in the engine drops. The 2QT memory is  recommended, but because of the limited space in the GTR, I have chosen the smallest with 1QT. For everyday use and from time to time on the racetrack, that's completely OK.

The installation is simple, actually. The line is connected with a T-piece between the oil cooler and the engine. Electrically, I have a switch to turn it off so that when you turn on the ignition for other reason than to start, the memory is not emptied. The problem is the space, I wanted to keep the oil line short, so I put it under the headlight. The good thing is you can see the pressure gauge through the side wall opening and and you can fill up the air pressure too. But you have to move the tire valve and the pressure gauge upwards at a 90 ° angle. Actually, you should install a Checvalve towards the engine to prevent the pressure from flowing off via the oil pump. Unfortunately, there is no room for that at my installtion. The pressure loss is probably very low because it works that way.

I recommend that for every car to add some prtection.

It is easier to install than an extended OilPan or even a dry sump.

Hope this is helpfull to someone !

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.

      Just saw this, redacted names. It's on a R33 GTS-t Facebook group. Looks like still teething issues.
