Got curious and searched the Bosch number. Doesn't seem to be what you're looking for. https://www.niparts.com/MAC/69BB43/BOSCH/0280230009.html

The competitive aspect of the auction is designed to determine "market" value. There was no competition here. If the guy put it back on the market would he get $130,000 or 250,000? That's a pretty big spread. If you guys want to show a sampling of Z432 prices over the years that would be more substantive than a Hagerty appraisal. Estimates from afficianados don't really have much weight behind them. It's like bench-racing. But the price paid is not my point anyway. The method of getting there is. Could be the guy read a Hagerty article and accepted their estimate and assumed that there would be competition. Who knows. It's interesting.

You're doing it again. I did not express amazement. I expressed bemusement at the guy's bidding. Read>comprehend>respond, if necessary.. I see several BaT's comments saying that because the guy paid it, it must be the correct market value. That's nonsense.

Making a high bid early shouldn't discourage anyone who "knows" the market. Anyone who can bid 1/4 million dollars can surely pay to ship the car to Japan. The premium market. I could see bumping it up in 10's to show your determination. But 120 is not rational, unless the purpose is to be able to say that you own a $250,000 car. Or a guy who just didn't know what he was doing. There's no way to explain away the oddness. The other guy I mentioned actually responded on the BaT page and said that he bid way over the last bid because he thought that was the car's value and he wanted to pay it. But one-person value is not market value. In terms relative to the whole market it's just one guy who "over-paid". It will be interesting to see if it pops up somewhere. The guy owns an old Packard also. His bidding made more sense on that car. https://bringatrailer.com/listing/1934-packard-twelve-1107-club-sedan/

By the way, I think that if the car is a Federal model it won't have the sensor because it won't have the catalytic converter. If the car is a California model the label on the door jamb will say "CATALYST". If it's Federal it will say "NON-CATALYST". Not sure if they left the sub-harness in anyway if it doesn't have a converter.

I found what seems to be the part number but can't find it in the drawing. Might be that the Bosch part has the same function. Seems like it would have a bimetallic strip inside that moves as temperature changes. If there's no strip it's probably the wrong part. https://www.carpartsmanual.com/datsun/Z-1969-1978/electrical/electric-unit-switch/section-2/280z/37

Regardless of thoughts on value, it's just not rational to bid like that. If money has value to you. It would be ironic for somebody who has $250,000 of extra income to not understand how to maximize the value of his money. Unless he has so much money that $250,000 is a drop in the bucket. Or he made money the easy way, by investing in something like crypto and it's just a number on a computer screen. I know some crypto people and they have tons of money and really have not worked very hard for it. We live in strange times. Maybe the buyer expected some competition. Or maybe he believed what the internet says is the "correct value" of the car. Whatever is going on, he probably could have saved 10's of thousands of dollars by bidding in a rational way. It's just weird is what I'm saying.

Another weird auction. There was one in the past where the guy made a huge bid, way over the last, and ended up getting the car. The guy that got this Z432 bumped the bid by $120,000 nine days ago. And won. Weird stuff. Not how auctions typically work. Money to burn. https://bringatrailer.com/listing/1971-nissan-fairlady-z-432/

Interesting that the Yves folks didn't set a reserve above the selling price. Maybe they just wanted to move it on. Based on past BaT results the 199 number should have brought more. Maybe the low number obsession is waning.

They just hang there. "Checking" terminals.

Only 30+ pictures, no driving video, no discussion. More about the resto shop. https://www.mecum.com/articles/st-yves-datsun-nissan-collection/

Mecum seems more like a muscle car nostalgia crowd. They should have put it on BaT. It a low miles low number car. Very clean looking, click the link. #199. It's even been restored by what looks like a pro shop.

There is an air temperature sensor in the AFM that is supposed to handle that. You might ohm it out and see if it's working. There is also the issue of winter mix gasoline. They make the mix more volatile so that it will light off and burn cleaner in cold weather. Modern cars with powerful computers and O2 sensors handle it well. Older cars not so much. The potentiometer on the coolant temperature sensor circuit is a simpler way to get a similar effect.

You might find something in the FSM. I'd guess that the Canada model runs richer at certain air flow and RPM ranges since the emissions regs were less stringent. The Fed model would be lean for the catalytic converter. Might be described in the Emissions chapter. I see that Rockauto put the AFM's in Exhaust & Emission instead of Fuel & Air. Odd, but might tell something. https://www.rockauto.com/en/catalog/nissan,1980,280zx,2.8l+l6,1209316,exhaust+&+emission,mass+air+flow+(maf)+sensor,5128

These are strange times. The Z432 is at a quarter millon bid with nine days to go. The top bidder has only been in the "game" since Feb 2021. He bumped it 120,000, from 130,000. Kind of scary. https://bringatrailer.com/member/ernestriggen/

Where's the throttle blip?! You were right there, reach out and do it! Looks good. Can't remember what's under that "distributor" cap.

I happen to have the 1986 200SX manual. It shows the older style shifter. And similar ratios. I had wondered if there was a four cylinder out there that might use it. Good luck.

P.s. There are also truck versions out there. They differ in overall length. You might measure yours and put the number out here.

I found an old picture of an 83 280ZX front case next to a 1985 300ZX case. The V6 starter position is actually lower not higher. Not sure what's going on with the FSM pictures above. A picture from the front of the bolt pattern and drain slot might help ID it.

The starter position seems high. I think that might be for a V6, like a 300ZX. Edit - The shifter would be different though. Not sure what you have there. People do swap front cases, 280ZX front case on 300ZX gear set, after some relatively minor modifications. But it will only bolt to an L6 in the wrong, tilted, orientation. Here's an 83 280ZX followed by the 88 300ZX. Notice how smooth the case is also.

Maybe the chain tensioner is loose and it takes a few revolutions to pump up.
