I won't mention this may have been discussed here in the last 20 years.

What use is your car, just regular street driving? Does your gearbox work well or crunch a bit on quick shifts? Are the gearbox and diff standard and original?

Hi.

New to the GT-R Skyline game so i would be happy to hear tips from you guys with experience. First of all, the oil game. What is recommended/what works? Its for diff and gearbox

For a transmission pick a GL4 75W-90 with synchromesh additives. For the differentials pick a GL5 75W-90, for the rear diff you will need one with additives for limited slip. For the front you can get away with using a gear oil with LSD additive but if you can find one without it the diff should live a longer life. I recommend doing some research with your favorite search engine if you need a more comprehensive answer than that.

Yeah, if you have a WRX...

75w-140 if you give a shit about your diff.

As Duncan said I think we've gone into detail about this more than once

For 5 Speed gearbox . Generally what people settle on if the box is in mostly good condition is Redline Shockproof Lite, the blue stuff.    Often confused with Heavy.

If the gearbox is in bad condition or shifts very harsh, Redline shockproof heavy, the red stuff.  For many has shown to give some improvement in the interim until overhaul
 
Motul Gear300 is also an oil that is popular among many GTR 5 speeds

      Has anyone used or considered Hi-tech mufflers, Bourke St Darlinghurst? They were the cream of the crop in quality and workmanship when I had my turbo Forester They specialized in custom stainless exhaust systems, especially for Euro supercars

      Don’t know if any one has noticed but there’s a few US spare parts companies that have purchased what seems like all the new old stock NISMO/Skyline parts and charging rich US dollars

      Also, the cause of fuel spills and smells from the top of the tank is almost always the rubber hoses that are up there, not the tank seal.

      1. No, as you say you can remove the connectors and fuel lines. Before you do make sure you remove fuel pump fuse and crank the starter a few times to release pressure, and also loosen the fuel cap (just in case the tank is slightly pressurised) as it will pump out the lines otherwise 2. Not necessary but you are right, if it is the factory pump it is at risk of failing after 25 years....Changing it is not hard but potentially not trivial as you have to make sure you have the right pickup/sock for the pump to suit the tank, need to make wiring connections (crimped butt connectors would be fine) and have to mount/adapt the new pump in the right place in the cradle. Not impossible but don't start the job if you aren't confident. Also, the plastic nut that holds that seal in place can be really hard to remove. If you don't have a fuel nut removal tool it generally requires a big screwdriver or similar to bash the ring around a few times before you can get it by hand. Also the fuel lines can be very sticky on the tank lid fittings, hose removal pliers can help or if not twist the hose on the fitting (eg with linesperson's pliers) to break the seal before you try and remove it. Finally, mark the feed and return hoses so you don't put them on backwards and seal them with an m8 bolt to stop crap getting into the lines while working. Add a little grease in the threads of the plastic lid when you go to do it back up as a gift to your future self, and make sure you put it on evenly/not cross threaded.  Having said all that, most likely the lid just needs to be either tightened or removed and put back on without being cross threaded...the seal itself is usually pretty good.
