Is it possible that you've misinterpreted the reference point for the 465mm measurement that appears in FSM drawing? The way I read the drawing, that 465mm measurement defines the distance from the so-called 'C-point' to the centreline of the moustache bar's chassis mount bushings (if you look really closely, you'll see the moustache bar's circular end loops defined just to the rear and inboard of the rear shock tower chassis mounts). Let's call this location on the vehicle the 'E-point'. The 'D-point' refers to the centreline of the top of the rear struts . But, according to the FSM drawing the centreline of the top of the struts lies directly above the centreline of the 'gearcase mounting rear crossmember' (which is a more useful reference point when taking measurements off the vehicle). The D-point sits 450mm aft of the C-point The E-point sits 15mm aft of the D-point (so 465mm aft of the C-point). The photo below (source?) provides a good visual reference for what all this looks like on the underside of a bare Z structure. As far as I can see (I could be wrong), the FSM drawing makes no attempt to provide dimensions for the location of the rear lower control arm and its mounting points. You'd need to construct your own layout drawing for the diff, moustache bar, and rear suspension in order to specify (in mm) the locations of the rear lower control arm and its mounting points relative to the C-point.

I snagged one of the earlier Nismo Safari Z Seiko’s back in 2023. They were a bargain at $299. I’d completely forgotten about it until a friend mentioned this new series and asked if I seen the news about it. Maybe it will be worth $399 at some point….. duPont REGISTRY NewsNissan x Seiko Debut The NISMO Safari Z Watch At SEMA, Li...When it comes to honoring motorsport history, Nissan knows how to do it in style. At the 2023 SEMA show, the JDM legend took the wraps off the new Nissan

The big irony with this latest Z-related Seiko limited edition is that - despite the big SEIKO stickers on a few of the Works rally cars (in some cases applied post-event...) the cars themselves were usually fitted with Kanto Seiki 'stopwatch' clocks and a matched pair of a HEUER 'Master Time' 8-day clock and 'Monte Carlo' stopwatch. The Heuers were there simply because that's what the international crews - especially the navigators - were used to trusting. Accurate stage timing - leaving and entering controls, special stages, road sections and service halts - was absolutely vital in the big events and HEUER were the go-to. No disrespect to Seiko - I've got a small collection of vintage Seikos and I wear one every day - but there were no actual Seikos in the cars this new limited edition links to.

If you have the filler neck clamped onto the tank and through the body opening, it will hold things in place very well for you to do the rest of the work. Harbor Freight has a coupon for that jack. It makes it a good deal. https://www.harborfreight.com/coupons I agree with @Yarb . I've used that jack for many things, including raising an oil drain pan up high enough so that the oil can't splatter as it is being drained from my truck.

Good deal! Keep that hammer handy!!

That scissor jack is a life saver. Used mine over and over for many applications?

Haha ya, I considered it, but at nearly 800 bucks, and for the first time in more than 15 years decided to pay a local shop to do the work to save the time of doing it myself. They dipped, prepped the inside, and painted the outside and for 500 bucks I'd expect some quality work. I wasn't happy with the job they did and basically ended up redoing most of it myself anyway. In the end, would have save more money going with the S30.world tank Thanks @siteunseen ! Will take a read through that once I wrap up the tank

Steve thanks for the comments. Yes, I am sure that the tank is the right size. I have several photos comparing my old one with the new tank. Not sure that I want to go for the trans jack just yet but that may be an alternative. Yes I've lifted the tank until reaches the top. However I've been working mainly with the end opposite the fuel filler end. Getting the fuel filler end in place first may help since that was the hardest to get apart. If there are additional thoughts I'm all ears. Thanks Rodger

When you click on Zed Head's link to atlanticz find TPS Adjustment and see if any of that sounds familiar. There easy to fix once you where the vanes are supposed to be. Oh yeah. Those AFM black covers get popped off and on all the time. I can't remember the times I've read on here of people screwing with the wheel and wishing they hadn't. Look for those factory silicone blobs.

Big thanks for the info! I hit the solenoid with a hammer then used the screwdriver method and the starter turned.

Idle and acceleration seem to be the problem. It cruises fine.

Hmm. I guess i will rerun the noid light test and then the fsm injector circuit test . What igniton tests do you recommend.

What i mean by " rough" the car starts easily, ( with an unplugged cold start injector ) , the car ildes fairly consistently, it does not stumble when settling back to idle it just sounds like a lumpy cam in an old Chevy or how the engine sounds when you retard the timing too much at the distributor . As for the afm I have not opened it up but by the look of the copious amounts of silicone holdingthe cover on i beleive someone has.

That plug IMO doesn’t look like it’s firing.

And if you can find an AFM that hasn’t been modified. The wiring harness itself could be the culprit. After replacing all of the connections on the EFI harness made a huge difference for me.

Eats, shoots, and leaves? Eats shoots and leaves. Runs, but rough. Runs butt rough. Just kidding. Are there any glue blob marks on the AFM adjustment screws? Match them up if you can find them. Nissan placed a blob of silicone on the wheel after it was set at the factory. What do you mean by "rough"? At idle, during cruising, during acceleration? It's fairly common for the 280Z's to run lean. There's a modification that can be done, described by Blue on his atlanticz pages. He also has an AFM "reset" procedure for AFM's that have been messed with. https://www.atlanticz.ca/zclub/techtips/EFI&fuel.htm

Hey everyone! I'm happy to say my datsun runs well enough to drive, however I beleive it has two problems . So I have a new regulator, new plugs, new injectors and checked the plugs and looked perfect, milky white insulator and electrodes looked polished ( too lean?) Literally the electrodes and ground of plug look like shiny bare metal . This is interesting because I began this journey with plugs that looked like dry dusty soot . (( Hella rich) so, also have new temp sensor ) i beleive someone has changed the afm settings in the past I welcome any opinions . So my question is should I consider the preload or the postion of the door. It is clear someone has been in afm . Thanks also it seems plug three is splash fowling but that's another problem I guess

Ok. Replying to myself in order to hopefully help someone else out in the future. This was SUPER painful to work out but the correct measurements were. From back to front: Rear of rear lower control arm mount to front of rear lower control arm mount: 456.5mm. This is 465-15+6.5mm. Next is rear of rear lower control arm mount to gearbox mount: 1434mm. This is 456.5+15+962.5mm The last one is from the rear of rear lower control arm to the strut towers. Mathematically its 2387.8mm..... This is the number that doesn't work. It comes from 456.5+15+1585+331.3. With my car however this number is closer to 2401mm. For the above 4 points the vertical reference is from rear to front. 285mm, 69mm 86mm, and 130mm. (To underside of front frame rails). I've mounted the car, its very stiff and ready to be deconstructed ....

as @Zed Head said, pull the spayed ign. Off the terminal and measure the voltage. Black to Gand and red on the spade turn the key to start. I think that he's just answering Yarb's question directly. Seems like you're getting voltage/current to the starter solenoid. Leave the wire off of the spade terminal on the starter and use a jumper wire or a tool like a screwdriver to connect the main battery connection to the spade on the solenoid. You can also run a longer wire directly from the battery positive for convenience. The starter should actuate. If it doesn't then the solenoid contact has probably crapped out. There will be some small sparks and the starter will work correctly otherwise. Make sure the car is in neutral and nobody has their fingers or other things by the fan belt. If you hear a solid click from the solenoid but the starter motor does not spin that's a sign that the starter motor has failed. Yout starter looks pretty crusty. If you try this jumper wire method and everything works then you have a problem with the wire from the ignition switch.

Managed to find a couple of the BRE cast aluminum adapters recently. https://www.ebay.com/itm/317146279997?_skw=Datsun&itmmeta=01K22V8ZHVKDFD1YZ2R67FYVVG&hash=item49d764303d:g:5ZgAAeSwYvNokRsm&itmprp=enc%3AAQAKAAAA4MHg7L1Zz0LA5DYYmRTS30kCoKfIwvB5xxhwqLfQsN2nCxk2lPQjX3YKVMYwrxYpvqUj44P448Su9W0IOyv9xeIAWjVrCeP8Fr2QU1TY9e7pNLlaT0BG9tj5zLexgY7byGGuH2yDK0OiyU3vR5fkXWKKN3IQdcSYmXNnnPXjRhXS2So%2FSPgQZXBaYiIZLQCVX3X7Vna%2FqJOosiRjsA69htfeltceq2Cf7k2gmZCY6J8H8hKNyQdK0sBnsetXbfjln%2FMlmTzAAStHKN2erVuANzBT9%2FZ1nAhivjZ33R04f%2B9W%7Ctkp%3ABk9SR4z5o9uQZg

The recommended prices on the website range from $1235 to $2665 to $3380 in US dollars. I have always owned Seikos and really like them but I don't wear a watch like I used to. As much as I would like to get one, they're too pricey for me. I can't see spending more than $500 for a watch / chronograph (old school) like that. Hell, I could get a Heuer for $3400.

Have you started to identify which contacts they used inside the shell? There are lots of different members within the family, and I'm not sure which ones they used. They are the split finger version and are not gold plated... Those two things you can tell from just looking into the connector. But beyond that, I haven't looked into it. And also within the family... There is JT (Junior Timer), and JPT (Junior POWER Timer), I believe the major difference is the inclusion of a spring (on the power version) to clamp the female contacts closed tighter. So if you're concerned with contact force, maybe you could "upgrade" a couple contacts to a JPT version instead of the original JT? Not sure it's even possible, but just a thought.

The tanks fit. What you don't say is whether or not you have lifted the tank all of the way in place so that it is hitting something. IIRC the last time I installed a tank (about 4 years ago), the key is to get the tank up high enough so that you can get the filler neck through the opening in the body. Also make sure you have the top vent hoses connected before you try to get it in place fully. After you get the filler neck in place, that will help hold the tank up. As for lifting the tank, if the car is on jack stands, this will do a great job of lifting the tank: https://www.harborfreight.com/450-lb-low-lift-transmission-jack-70262.html That way you can use your 2x6s to help get the tank to the right height.
