Doesn't make sense
Are you on your phone? Maybe phones handle the site differently. I am using Windows 10, Chrome browser, HP laptop. The first image I posted was from the "Topics Last 30 Days" page. Snipped and pasted. https://www.classiczcars.com/discover/112/ The second was from widget77's profile page. Snipped and pasted. https://www.classiczcars.com/profile/10902-widget777/

Z's on BAT and other places collection
There's nothing to manage. It's just a single thread in which to talk about Z's that are being sold or have sold. As opposed to multiple individual threads. If you read back through the posts you'll see that the concept works. Even Mike has commented here.

Tank to pump hose routing
That is a "colder" than spec spark plug. Might be why the electrode on 1, 2, and 5 are dirty. The white ash on 3, 4, and 6 looks pretty good, but still on the cold side. Have you adjusted the valve lash? It looks like you have some cylinder imbalance. https://www.ngk.com.au/technical_info/heat-range/

If I click on 3X minutes from the main page I get taken to the first post in a long thread. If I click on 3X minutes from the poster's profile it takes me to the last post. Weird.

No pulse with fuel rail unbolted?
The injectors open after every third spark. Spraying half of the fuel called for. You can test by spinning the engine with the starter or by disconnecting a wire from the coil and tapping it to its terminal quickly, with the key on. There will be a small spark each time and one of the spark plugs will spark so be careful. Every third tap should cause a squirt of all six injectors.

Z's on BAT and other places collection
Hate to complain but this inability to one-click to the last post is really a pain. And having the first post repeated on each page is too. Very cumbersome. Anyway, the 77 Turbo Z had an $11,000 Rebello engine installed after it was bought for $25,250 in 2018. Plus another $25,000 to have it all put together. $61,000 just to break even. Will it sell? Doubtful.

STM PRO ECU Conversion
Here's a link to a US source. p.s. has anyone else noticed that people seem to be leaving words out of their sentences? You can figure it out but I've noticed it across the internet. It must have something do with writing on a video screen or something. Some kind of odd mental glitch. Very powerful what? Where's the subject of the sentence? "The STM PRO !

Transmission Swap and other things
The widths vary between brands. Just make sure that there is no groove worn on to the sealing area of the crankshaft. The seal does not have to be worn out to cause a wear groove. I just did a repair sleeve on a rear end pinion shaft. Big wide wear groove, not the typical thin seal spring wear.

Vacuum S line 280z
Yes, it's strikethrough. Couldn't remember the name. It's here in the first box, but not the Edit box. Weird. I had one on my 76 but maybe it's an AC system only thing. I had AC.

Vacuum S line 280z
The check valve is designed to let air pass out of the bottle and in to the intake manifold, (darn it, I knew I'd do that), but not from the manifold to the bottle. The hose with the check valve is the one that loops around to the tiny nipple on the top of the manifold. Suck on the valve to determine which end points toward the manifold.

280z water **** removal sequence
Should work fine. If there's no leak you don't really need to add coolant. The ability to hold pressure will tell you. But if it doesn't hold pressure then you'll need to add coolant to see where it's leaking from. Unless you have good ears and can hear the air hissing out. I'm going to guess though that you might have problems getting the cap to fit correctly. Just the odds, the right size and fit might not be in the kit. You might get lucky though.

280z water **** removal sequence
That's a lot of money for a one-time test. Why not just fill it with water, start the engine, and see what happens? Worst case you spill some water in the cabin. Put a towel under the valves and cleanup should be easy.

What testing method will you be using?

280z water **** removal sequence
The system pressure will equalize without opening the valves, there's coolant on both sides. If you start the engine and let it get to temperature you'll generate pressure. The main concern would be that if there is a leak, it will be hot coolant instead of cold.

Vacuum S line 280z
They can be switched. There's no mechanism inside the tank. The check valve is important though. Be careful with the hoses, they are an odd size and tend to split because they're so old. I spent a lot of time fixing mine, as they kept splitting at the ends, then the check valve went bad. Overall, it was a pain keeping everything working right.

I'm the one that reported my car(s) would not start with the tachometer disconnected. Actually, if I recall right, it was two cars, my 76 and a 78 parts car that had a good engine. The 76 phenomenon went away after I changed to an HEI ignition module. So, it seems to be a thing only with the factory ignition system. So, basically, if you try to start it without the dash installed and it doesn't start, don't freak out. You might just be the confirmation case. Good luck. One other thing to be aware of is stray wire ends that might be powered with the key on.

280z DASHBOARD REMOVAL / UPGRADE
Just for fun, here are the bulb specs from the Owners Manual. Can you show a good picture of the type label on one of your bulbs? Just curious. Today's 57's seem to be slightly larger than yesterday's and don't fit the space very well. I don't think that 57X is available if I recall correctly, except for NOS eBay stuff.

Here's a different guy that says the fog lamp option was Japan market only. So if that's correct then Nissan was basically cutting costs by not producing non-Japan market dashes. They just left the spot open with no option for non-Japan market customers to fill it with anything. Unless they got creative, with something like an F knob. https://jdm-car-parts.com/products/original-style-fog-lamp-set-for-jdm-fairlady-z-datsun-240z-260z-280z-510-roadster?srsltid=AfmBOoq9Z4T801ioQzmLJnAbk5VItXD-5LYHbUtRaHKJH_TFZvNyk7Os

1970 Wiring Diagram
There's an empty hole in 1971, then there's a Nissan factory labeled cigar lighter in 1973 in the exact same spot. About as far from bizarre as a logical person could get, I think. It would have made more sense if there was an optional cigar lighter. Maybe there is, the wiring is probably the same as for the fog lamps. They should have put that information in the Owners Manual, instead of just showing an empty hole. Beside that, do you have any documentation describing the optional fog lamp switch? And the fog lamps, which, of course, would need installation also. That would add a lot to the discussion. Much more interesting than a single comment in a forum. The details and official documentation. They could have gussied up the hole a bit. At least by 73 they had a molded-in spot for the four-way sticker. https://bringatrailer.com/listing/1971-datsun-240z-276/

I got curious about the "F" knob when I saw this and looked around my favorite place, BaT, to see what was "supposed" to be there. But I only looked at 70's and 71's. Then this new car came up , a 73, and it has a "cigar lighter" there. I looked in the Owners Manuals and see the drawing of the spot with no label in 71 and the labeled spot in 73. Kind of looks like Nissan was planning to put a lighter there but didn't get it done until 72 or 73. I just got the 73 Owners Manual from Xenonzcar. That site is still alive. https://bringatrailer.com/listing/1972-datsun-240z-354/ #107 1971 OM 1973 OM
