Z's on BAT and other places collection
It's worth what someone is willing to pay for it. However, the main problem with what the current market is willing to pay is the color change, never a good idea. Also, there are a few body/paint issues that the listing details. The old market might have been willing to pay as much as - my opinion - 80k but the current market did indeed speak. The upper middle class collector car market is keeping their powder dry.

Datsun-240z Vs Fairlady-z432
Hi, I did some work refreshing for metal headlight bowl case of my Z432. In Japan, headlights case has a note “右配光” (Aiming to the right) and “L o R.” Is that its lens cut different? I have a new set of the light bowl but I don’t want to use it because new replacements from Nissan has different shape of the plastic screw cover.Original is also a see through plastic but new one is white. So I cleaned it and painted it with hand written “右配光 R(L)” “12V” Please note earlier type doesn’t have tiny holes for retaining the rubber seal to the metal bowl. Kats

Discover various "date",use cross-reference method
Hi, Have we discussed this before? The date code appeared on the MIYAMOTO horn. 01/70 Z432 has S 12, 03/70 240Z has T2 06/72 240ZG has V6 So I read it like this, S 12 means 1969 December T2 means 1970 February, V6 means 1972 June. How about yours? Kats

Restoration of BringaTrailer 240z - HLS30-35883
Yesterday and today, I spent some time working on the car again. I haven't been working on it much, as I have been working on my track Z some more instead, and I had tenants move out, so I have been spending some time over the last few weekends at a rental house doing things that needed attention. I am still hesitant to modify my SM spec SU needles. Taking a lessor path of resistance, I swapped out the 10W-30 oil for some 20W-50 to see what a difference that would make. What got me thinking about doing that was the "drop test" of the SU pistons. From fully up to fully dropped, there seemed to be almost no damping. So, I decided to try a change. Comparing/contrasting, the throttle response is not as lightning quick as it was. However, the lean condition on overrun is noticeably less. I think I like the 20W50 better overall. I might try 10W-40 as well to see about getting a bit better throttle response (for rev matching downshifts). If I am cruising and I snap the throttle fully open, the engine and car respond quickly - it accelerates nicely. So, maybe the 20W50 is fine. I don't know what to do regarding the SU dampers. They are original Nissan ones - probably original to the carbs on the car. The "barrels" seem to have wear, just judging by their appearance. The barrels have an OD of a little more than .346". I purchased an SU rebuild kit, which came with new needle and seats, and dampers recently. However, I didn't use either. I found the problem with the existing needle and seats. The rear one just needed to be polished inside to keep it from sticking as when it was machined, it was finished with a coarse finish. Also, the new dampers have a "longer throw" than the original ones - the sleeve portion of the damper has a longer amount of free movement. I didn't want to introduce that change, so I have held off on switching them out. Also, the new damper sticks do not have low and high marks for oil level like the original ones have. However, the barrels measure at, or just above .346", just like the "worn" originals. So, again, given all of these things, I didn't feel like installing them. At present, I have the mixture nuts turned out precisely 2.5 turns front and back. When warm, the AFR at idle is around 11.8. At cruise on flat road, the AFR is about 14.8. I still see AFR get lean if I try to accelerate a small or medium amount. This often happens when the road changes to a slight incline. AFR on a slight incline, trying to maintain the same speed tends to be in the high 15's and can reach low 16's. If I smash the throttle to the floor, I typically see AFRs in the 12.4 to 13 range. With the 10W-30 oil, on long instances of throttle shut deceleration (like from third to second - rev match, and then just decel in second with throttle shut), the AFR would climb up to 18s... or 19s even. With the 20W50, AFR will spike lean on throttle shut decel for an instant, but then AFR will return to normal range (13 to 14). Much less popping from the exhaust with 20W50. I need to do some data logging again so I am not just pulling these from memory. I haven't heard of anyone with Hitachi SU's changing the springs, but watching various Youtube videos, it seems like changing springs is pretty standard with tuning British SU's, and it is typically done before attempting to modify needles. It looks like order of march is springs, dampers, oil, then needles. I think I'd like to try some springs which are bit stiffer. And I'd like to try 10W-40 instead of 20W-50. Maybe I will do these things before I try to modify the needles.

The OG 240Z - Reanimation Project
I messed with the radiator hoses today and had some of the same issues I had before. Here's the lower rad hose: \ And here's an example of how unattached the braid sheath is to the rubber underneath: And this happens when you slip the hose clamp over the end: And here's an example of the inconsistent braid density that I mentioned earlier. Most prevalent on the outsides of bends, which makes sense. Some areas are so sparse that there is big gaps in the braiding. Looks like this: Compare this to the original stock stuff: I know you can't get the stock stuff anymore, which is why you end up paying "only game in town prices", but still... This is what it says in the description: "All of our braided rubber hoses are very accurate replicas of the factory braided style hoses, they have been carefully molded to have the exact curves and bends like the originals!" Maybe they had a bad batch where there were quality issues. I just don't have the time to deal with it now. Maybe after Zcon. I also see in the ad that there is a warranty. I'm going to look into this when I have some time to breath: "We are confident in the quality and craftsmanship of our products, as a result we cover all of our products with our Resurrected Classics Parts Promise. This is a Lifetime Warranty that covers any manufacturing defects with your product during your ownership and entitles you to a new replacement of that part with free shipping.

1972 240z tachometer not reading nor working with MSD blast 2 coil. Any solutions?
My mechanic finally solved the 11 year old problem by resdjusting the carbs with the temperature of the car during traffic jams, 3/4 of the Temp gauge and an MSD blaster coil. Now he is asking me for a diagram or schematic to get the petronix 1.5 coil and 1.5 ballast resistor running and the 1972 240z tachometer working alltogether. Can seem to find it in the web or haynes manual. Do you have any reference for this? Guess the stock tachometer wont work with the MSD blaster 2 coil.

Z Restoration Progam
Greetings and welcome to the group, HLS30-365101. Some pages ago, we were discussing the quality control checklist. At the urging of SpeedRoo, I dug through my files to find my copy of the "240Z Restoration Program Quality Control Checklist". The checklist I have is some 40 pages with an introduction overview page and 20 or so pages of procedure descriptions organized by component with columns for notes, sign-off and date. For instance; under the brake / clutch / hydraulic component, one of the procedures is "All rubber brake hoses: replace" and in the notes column it says; "Use DOT 3 brake fluid". During the restoration program there were two final inspections and four inspection sign-off points during various stages of the restoration process. Of note to our Plating conversation; checklist item "All steel brake lines: check for kinks, condition of flared ends", notes "Cad plate all brake lines possible. Replace any corroded lines." Attachment D of the checklist is a two page copy of Wick Humble's book; "How to Restore your Datsun Z-Car" discussing fasteners, everything about fasteners from engineering standards to thread pitch and sizes. From Attachment D; "How about the fastener's finish? The manufacturer plated every metal fastener...on the Z car, it is predominantly what platers call yellow zinc, that multi-tinted golden finish used on most bolts and nuts exposed to the elements. Plain natural-colored zinc is also used on some parts."

Z Cars On TV And In Movies
Pretty late to the party but both Z’s in the video where (I believe) owned by the same guy at that time. He unfortunately sold the orange one and repainted the gray Z to yellow but ultimately sold that car as well for a BMW E92 M3. He now goes by @Dutch_e92m3 on Instagram.

My Listing: 1970 240z 4 Screw SU Carb Kit on eBay
Something's wrong with the first listing. Broken link. The $589 is "Buy it now" and the other is an auction, with three bids to $56. I don't know if EBay auctions have a reserve or not. I'd guess maybe the seller can just not complete the deal? From what I've seen, the way to set a reserve on eBay is to set the reserve as the minimum bid to beat. Maybe he forgot or doesn't know to do that. The $589 is $539 with a coupon.
