This is the Jet Hot cast finish. Please excuse the slightly green cast which is the result of either lighting or camera user error. I like the color but more importantly it's extremely robust. After more than 25 years the exhaust manifold on my 280 still looks like it was just done. Hope this helps. Not a job one wants to do twice. PS This is the exhaust manifold from the Z used as the model for the Franklin Mint Z car

My 3.12L is finally going in!

I got back in the shop today. Rear bumper is on. I don't like the fit but it's on for now... License plate light and hatch badges and I think the rear end is done Also worked on installing the leather pieces over the wheel arches I trimmed one of the last pieces and hemmed it with glue

Oh.. Americans with theire abriviations... 🙃 LET'S FIND OUT.... ;-) I took a run after reading a few lines... do you too? 😄 (From acronymmap.com) When it comes to quirky acronyms, SWMBO is one of the more humorous and culturally loaded ones. Short for “She Who Must Be Obeyed,” it originated from the 1886 novel She by H. Rider Haggard and was later popularized in British pop culture, especially by the TV series Rumpole of the Bailey. In modern usage, SWMBO is often a tongue-in-cheek way to refer to a wife, partner, or authoritative woman—sometimes with affection, sometimes with sarcasm. It’s playful, but depending on the context, it can also carry undertones of reverence, exasperation, or humor. But what if you want a different way to express a similar dynamic—whether you’re writing fiction, creating dialogue, or just having fun with words? Here are 30 alternatives to the “SWMBO acronym,” each offering its own spin on authority, affection, or dominance in relationships, with tips on when to use them. 💬" src="https://s.w.org/images/core/emoji/16.0.1/svg/1f4ac.svg" style="box-sizing: border-box; vertical-align: -0.1em !important; border: none !important; max-width: 100%; height: 1em !important; display: inline !important; box-shadow: none !important; width: 1em !important; margin: 0px 0.07em !important; background: none !important; padding: 0px !important;"> 30 Alternatives to the “SWMBO Acronym”1.

Still waiting for the silicon rubber fuel lines, but in the meantime disconnected the fuel filter and took a container with new fuel, connected to the fuel rail. I made sure to purge the questionable fuel. Cranked the engine, coughed and sputtered and the engine actually started. It was running extremely rough, couldn't even tell if it was all cylinders. Once I cleaned up some spilled fuel on the ground, I'll try again. The fuel level is set to 10 turns (10mm) below the bridge. I then set the nuts on the nozzles to 2.5 turns out from the bridge. I should pull the plugs just to see what they look like, hasn't been running in probably 5-10 years. As the engine ran, I could even hear the electric fuel pump running, thus fuel on the ground. I'm going to connect the fuel system back to kind of normal, where it will suck clean fuel from a gas can, as the tank is dirty. I also need to put some 20 weight or atf in the carbs, think I've used too heavy oil. I didn't have the engine running long enough to experiment with mixtures yet. I'll keep you posted, not out of the woods yet. Jim

So Cody and I got the tachometer working tonight. Big thanks to @cgsheen1 Chuck. His explanation for current flow to the tach and back made it all make sense. I took the tip of my thumb off with a hammer tonight in the shop, so I didn't get the last piece of leather in. Opposable thumbs are really useful, as it turns out.

I used BSPT fittings on the N33 balance tube I have in my 260Z when I was doing the fuel injection conversion.

Read the articles here about the GM HEI module, if you find that your wiring is smoked or the factory Transistorized Ignition Unit (TIU), aka ignition module, is gone. You can run wires in the engine bay directly from that terminal block with the green and red wires. https://www.classiczcars.com/articles/electrical/

The reaction disk won't just fall out all by it's own. If this problem occurred all of a sudden, it's not the disk. A torn booster diaphragm will cause a hard pedal, and so will a malfunctioning poppet valve inside the booster. Either way, you're opening or replacing the booster.

I'm going to need to get some replacement floor pans as well. I have had at least three separate people tell me to go with KF Vintage. One was a contractor that had done previous classic car restorations, another was a vendor at the Carlisle Import & Performance Nationals, and another was a Z mechanic. Needless to say, that's who I will be going with when I finally pull the trigger and decide to replace my floors. Mine were filled in with old Maxwell House coffee cans and lots of filler by a previous owner that did not want to weld. I was planning on replacing my floors as this winter's project, but I may need to put it off due to the persistent Gov't shutdown. Not having a current and reliable source of income may stall my plans somewhat.

I am well pleased with the MSA Ceramic Coated Header and Premium Exhaust System I installed some 14 years ago. The fitment was spot on, the OE heat shield fit without bending or mods, no interference with the steering rod or frame rails. The supplied Turbo muffler was a bit loud and had some drone at 3k RPM, a 12" resonator I later installed cured that and softened the sound a bit. A local shop I use was very impressed with the overall design and exceptional quality of the entire system.

While I have turned much of my attention to my other 240Z recently, there are still quite a few things on the to do list for this car. One of them was replacing the glove box hinge/panel. My old one had broken at one of the three hinge areas. I was lucky enough to find a NOS one. Having recently replaced the decal on the original one with a new decal, I had to procure another new decal, and put in on this new panel. I still have some alignment issues to work out before the glove box will shut properly. The Vintage dash that is the car requires a bit of trimming of foam and vinyl on the lower edge of the glove box opening to allow the hinge to operate properly. Another small item on my list was to install these plastic seat belt buckle trim plates (old foam on the right, new on the left, which I glued to the center backside of the trim: These go here on the 1971 belts: I used a heat gun to warm them up quite a bit before snapping them into place, which went without issue thankfully. I still have a bunch of details like this that need to be completed. I would like to swap out the headlights bulbs for some other Koito H1 type ones that I found which look more like the originals. There are various other markings I'd like put in place to replicate factory ones (paint markings). I also would like to get the original wheels refinished and get some stock sized tires mounted on them. The original hub caps that I have are very nice, but if I can get better results with the paint color experimentation, matching the original much better than my efforts thus far, I will refinish them. I still haven't done anything to address the lean condition that I am experiencing. So, that is still on my list. After about 4 rounds of pulling the valve cover off to adjust the valves (the valve noise was much more than I can recall with my other L series engines), I figured out part of my problem. I have generally been adjusting valves with the engine cold, but sometimes when it was kind of warm as well. I was sure it would tighten up as the engine got warm. What I have found instead is the the lash clearance actually grows a bit when the engine warms up. The specification for my camshaft is .006" on the intake and .008" on the exhaust. I started off with setting the clearance at that spec with the engine completely cold. I then found that the lash was a bit larger with the engine lukewarm and a bit larger still with the engine hot. Seeing this, and after resetting lash a couple of times prior with no improvement, I decided to use .005" and .007" while the engine is cold instead. With that I achieve notable improvement.

My now closed shop generated 4 Gold medallion stock 240 recipients. We tried 2 different finishes for exhaust manifolds. One was a finish like you're using and the others had Jet-Hot cast finishes. In EVERY case the judges (?) said the finish was incorrect and deducted points. Our last Gold Medallion car was judged (?) to have a steering wheel finish which was "too shiny". Go figure!!!

Pretty happy with how this looks. Sprays on very nicely.

BOT.... btw.. Matt have you finished your car?

@siteunseen Our “Forum Librarian Guru” Strikes again!!

I'm taking a year off from life. 99% of the bad ones are from pushing to fast to get back to work. Not me, I enjoy being at home.

Is BSPT a possibility? The prevailing internet Z forums' "wisdom" is that the oil pressure sending unit holes are BSPT. JIS VS BSP: What's the different ?Before choosing a suitable thread standard, it is necessary to understand from various aspects. This article will introduce the difference between JIS and BSP, so that you can better choose the thread

I used aluminum aircraft rivets - and like your pop rivets, I should have used a semi-tight washer on the squishy end. The sheet metal on the contacts is really thin. I also "re-squished" the (original) rivets on the bulb holders.

Some of the holes had real taper plugs, pipe threads. Two of the taper holes were about 10mm and somebody had forced straight thread bolts into the taper holes, ruined the threads. I might be able to chase them and put in 1/8" taper pipe plugs. I don't know that the bolts made a good seal. I"ve verified that some of the threaded holes are 1/8" NPT 27, I'll chase the threads and with teflon tape will repair the holes. I have a 1/8" to barb adapter I can connect my vacuum gage, haven't used it in years. Jim

I agree with Patcon. I'd cap off everything you don't really need right now, including the brake booster and the transmission. And yes, I think a vacuum gauge could be helpful. You should be in the 17-20 inches of vacuum at idle. If you're at 10, there's a leak somewhere. I also think pics could be helpful.

Oh, and I'd be hard pressed to believe it's a malfunctioning check valve. If you're off the gas pedal when you're on the brakes (as you most likely are), the check valve won't really matter because the manifold vacuum is high (because you're off the gas pedal). Does the idle go up a little bit when you press the brakes sitting at idle? That's a typical sign of a torn diaphragm.

Hahahaha!! It's true!!

I made some progress last weekend but not quite there yet. So I drilled out the two rivets at the switch. Replaced them with aluminum pop rivets for now. That made it better but it still didn't work. There was also a continuity issue at these other rivets The only problem is I used a grinder and as the rivet heats up it melts the housing. A die grinder might be a better choice. The LED lamp I was using worked for a moment then freaked out and wouldn't go full brightness. I ordered some more. So we'll see. I would like to replace the aluminum rivets with small copper rivets if I could find some good candidates and a proper way to staked them. They need to be about 0.095" or about 2-2.5mm OD

I think I would cap everything on the manifold that uses vacuum with an assortment of rubber caps. Then if you can get the engine started and sorted, add them back one at a time to check for vacuum leaks

Couple comments to hopefully help the process... So I don't know exactly how you are handling the choke lever, but the typical process is to give it a good pull, crank the motor, and then as soon as it starts, push the choke lever forward "some, but not all the way off". It's not unusual to need partial choke for several minutes to keep the engine running smooth when cold. If you're pushing the choke all the way off immediately as soon as the engine starts, you are probably moving too fast. Give it some time to warm up with partial choke before you try to get the engine to run with no choke at all. Engines don't like to run cold. and engines that have sit for decades are usually grumpy about being woke up from their sleep. It'll probably get better as you get more time running, but first bunch of minutes on an engine that hasn't run in a long time? Don't expect perfection. Next is there's no way you should need to be running five turns down on a stock motor. If you're thinking you need five turns down, there's something wrong somewhere. I'm hoping that it's as simple as you need to leave the choke on partially for five minutes, but if the engine is warm and you need five turns.... There's something wrong. And that "lifter" on the bottom of the carb does not make things richer on that carb, and in fact, it does the opposite. When you lift the piston like that, it completely disables the carb by making it super lean.

I haven't posted in a while.....hope life is treating everybody with kindness The single best thing I have done to my braking system was to install a larger 8" brake booster. Best of my memory 69-72's had a small 7" booster. Nissan updated the 240 brake boosters to a 8.5" in '73. They knew the boosters were to too small and corrected the braking problem. You also may want to inspect/replace your brake booster check valve. I did go a larger caliper but never got that great breaking feel until I completed this upgrade several years ago.......This made a HUGE DIFFERENCE in my braking power. JDM-Car-Parts use to have an upgrade for 69-72 that had the correct bolt pattern to accept into the firewall. That made the transition from a 7 to 8" a breeze for me with no extra drilling. https://jdm-car-parts.com/products/datsun-240z-1969-1972-8-inch-brake-booster-upgrade-kit?variant=31778739748973

The needles are adjust correctly, one takes a straight edge along the piston to make sure the shoulder on the needles are correct. There is a lot of history here, had a very difficult time getting the needles and floats adjusted right in the bloat bowls, that took an enormous amount of time. I have a tach on the coil, next is to turn the nuts to go on the rich side, then rock back and forth to lean, looking for max rpms, at least thats what I understand. I've been running fuel out of a 5 gallon gas can, the excess goes back into the main tank, ran my gas can out of fuel. The fuel tank is somewhat rusty, need to find if it is usable or now.

I have a maxima rear disc conversion available you're interested...

I wonder if the needles are set too low in the pistons? Closing off the fuel with the choke off

Front Willwoods are an easy install. Fronts are where most of your stopping power is. I just put the fronts on all but one of my cars…..they will really put your head towards the windshield. I use my stock Master cylinder with no problem even with the Z with front and rear Willwoods. A hard pedal usually is caused by a lost reaction disk in my experience. Don’t know what else causes a hard pedal.

Installed new fuel hoses from ZTheraphy, they are more flexible than my other hoses from the hobby shop. Fuel may have been OK, but running new fuel anyway. With choke all the way on, nuts about 2.5 turns down, starts with ether. Then RPMs picked up and engine ran for the first time. As I reduce the choke to the point where the choke is off, the nozzles all to the top, engine coughs and dies. With the chokes on again, engine runs, very clearly the carbs have been set too lean. I'm thinking about setting the nuts about five turns down, that should richen it. Then run it with the chokes on and gradually back them off. I think if I keep trying that and can get it to run with no choke, I'm in the right direction. If I get that far, I can start adjusting the mixture, one carb at a time to where the idle RPMs peak. I would then go back and forth between carbs for peak RPMs, once I get it stable, then synch the carbs with the unisyn and set the idle RPMs. BTW, have not done any actual testing for vacuum leaks. If there is a leak that happened by itself, I might check the vac assisted brakes, it has a large rubber diaphragm that could be rotten. I'm 77, and have forgotten a lot about this stuff but it's coming back. I think I'm in the right direction, appreciate comments. Jim

You might find some things here: https://junkyardjenny.com/

Need a lot more info to help with this . Ignition set up ? Timing at WOT ? Still running vacuum advance ? What year head ? Was the camshaft degree’ed? Camshaft specs ? Engine compression ratio ?

Nice, correct engine block color. I had a great black wrinkle color paint when I first did my turbo swap but they apparently quit and I have yet to find a decent substitute. Yours looks pretty good. Mine could use another refresh...

Pre-Fleetwood Mac Fleetwood Mac.

You can add a relay as cgsheen suggests, which will take the current to the solenoid out of the switch, or you can bypass all of the inhibitors and other safety features. I would start by checking for voltage on the wire that comes from S on the ignition switch when you turn the key to Start. If there's none there then you need an ignition switch. If you have voltage then you can add a relay or by pass each safety on the path to the starter solenoid. It would be best to also test under load, using a test light that draws some current, like a taillight bulb. I have found that the staked pins (copper color) can get loose and lose contact with the terminal. I had a 78 switch that would grab the starter then let go as I turned the key. The pin was loose. I fixed it with a hammer and a chisel. The terminals are marked with molded in letters. Look closely if you remove yours.

SWMBO ;)

Haha!! Not sure. Who would I ask for confirmation? ☺️

I just ordered a pair from Z, I've used silicon rubber hoses before for other gas-related things, they would eventually get soft, but I'm told their's is made for gasoline. I'll do a visual again, looking for vacuum leaks can be difficult, if the engine was running one can use propane that gets sucked up from the leaks and you can hear it in the engine, but this guy won't start yet, oh forgot, need to use new fuel to be supplied directly to the fuel bowls. I'll keep you posted, hopefully getting close. Jim

I wondered if it could be for air conditioning

I've just re-visited this 2020 post. In hindsight, I think this may be the definitive photo essay on the design and construction of S30's 'dogleg' structure. I wish they all looked like this but, as Inline6 notes, the structure is completely missing on far too many Z's (replaced by bodge and newspaper, topped with a Tabco panel). If your Z isn't sound in this area, don't count on your lower seat belt mounts (yours and your passenger's) if you're involved in a collision.

Thanks for the imput, I am going back and forth between the options. I know i'll have to do fabriation work to get the Z depot floors to fit, but I dont mind fab work. I just dont know if theres more of a pain getting seat rails mounted or other obstacles that will creat a conflict. I just got a 1977 280z as a project and the previous owner decided the best way to make his car look dfferent was to add about 200 pounds of bando so i feel you on that. gotta love a good project.
