The home of the classic Datsun Z

I've seen a few people on the site use one of the AI "chat bots" as a source of information and thought it would be worthwhile to start a topic about it. A sort of public service thread. Recently I've seen some Youtubers use it as a source in their videos but I've also seen a video where a guy showed how he manipulated AI to make him the #1 computer repair data recovery shop in the country. According to to AI. Then I just came acrosss an article on the same topic. In short - AI is only useful, i

In anticipation of owning my 240Z for 40 years, I have ordered brand new Zerk / Brake Bleeder Caps. They will arrive at my home in January 2026, 56 years after the vehicle rolled off the production line. Keith

Is it safe to replace only the coil to distributor wire with taylor 8.2mm cable and leave the other 6 ngk ne61 blue spark plug wires as they are? I noticed the blug ngk coil to distributor wire measured 3.74 k while the same taylor wire mesure 76.4k.

Hello all,    I am going to document my build.  Basically I have a garage kept series 1 240z.  That hasn't driven since 1986, it needed brakes which she couldn't afford so it has sat since.  It was resprayed in the 80s as well.  Some bad overspray but overall it's a very rust free car.  I actually found it in my neighbors garage.  My goal is to drive it and enjoy it, but it needs some TLC.  First and foremost I got it running, and that is when I made the decision to keep it and I have

This is the first time I've ever replaced a flywheel so bear with me. I bought a Fidanza 143281 aluminum flywheel some time ago and will be pairing it with a Centerforce II clutch, as per the recommendation of the folks at Motorsport Auto. The flywheel came with three dowels and there are nine blind holes drilled into the flywheel where they might reside. After test fittings, I found the combination where the clutch engages with the dowels. So far, so good. The kit also came with a small tube

Hope your week is going well. I just noticed a bit of "weeping" at the fins on the engine side of my radiator.. Local club guys are suggesting an aluminum radiator, but I like the stock look. The current radiator is a four row, with the original tanks and the little guard on top. I have had this one rebuilt a couple times, so was thinking of just taking back to the same radiator shop and have them go through it. A few guys here were telling me that you can't keep rebuilding an old radiator.....

Hey Everyone! I wanted to share a new microfiche/resource sharing website I've been working on. A couple years ago I bought a full set of microfiche slides for the Datsun Zs and scanned them at my local library. I wanted a more easily searchable database of parts and the ability to add things like torque specs, notes, or references. The result is at the link below! Still a work in progress as I still need to verify and clean up the information and number callouts for about 80% of the diagrams bu

Wondering if its safe to use an MSD 2 BLASTER coil (0.7 ohms) +1.6 ohm resistor with a Pertronic 1761 ignitor module installed in a stoch hitachi single point dizzy? I tried contacting Pertronix and they argue that there is no need to use the resistor at all. This doesnt seem right. Im trying to achieve a good spark at idle. Any advantage or disadvantage with this setting?

So many Z's, of all numerologies, have popped up that I thought it might be good to collect them here.  Feel free to add old or new stuff.  There's a bunch out there right now, for some reason. https://bringatrailer.com/listing/1975-datsun-280z-26/ https://bringatrailer.com/listing/1976-datsun-280z-38/ https://www.classiczcars.com/forums/topic/64614-1270-on-ebay-barn-find/ https://www.classiczcars.com/forums/topic/62501-brand-new-280z/ https://www.classiczcars.com/forums

I have triple Webers for my L28 and they came with banjo fittings for the fuel inlets. However, the fittings only have metal washers for both sides of the banjos. Even at the rather low fuel pressure needed for carbs, I don't think that metal washers alone are a good way to ensure against leaks. Buna-N rubber has high resistance to gasoline so I was thinking of using O-rings or thin flats cut from 1/32" sheet material in addition to the metal washers. But in doing so I'm not sure that the sta

Hi all, I've just received my 1973 240z! The previous owner towed it out from MO for me along with piles and piles of parts. We went over it together and it's in better shape than I expected (it was a Craigslist transaction over the phone between MO and NJ). I'm sure that I'll start finding nasty surprises once I start into it, but for now I'm basking in the glory of having a Z in my garage.    

Hi, I’m Matt. I’ve been a member of Z.Car for a little and figured I’d jump in here too because I’m always lurking.   I have a pretty rough 79 280ZX that I’ve had for maybe 15 years. It’s has sat for about the last 10 or so. I daily drove it for a few years, then let it set after some slight running issues and started a family so some of my side projects got put on hold.   I had to move the car from where it was being stored(barn) so I got it fired up and running and all my old dreams of doing s
