Judging on past performance, if it *did* get added to Zhome.com it would probably have a heavy amount of spin added to it - whether intentional or unintentional - to support a natural bias that is at once both unscientific and unscholarly. But the real tragedy of Zhome.com is that it amounts to 'Friendly Fire'. I still don't really understand why the concept of the S30-series Z 'family' of variants - at concept, then through design, engineering and production, and all of them influencing each other in one way or another - is so controversial, let alone abhorrent? This is not some kind of 'woke' re-writing of history, it is documented and demonstrable fact from the very top. But then, this is the mindset: ...and those quotes are all from discussions on this very forum, classiczcars.com Turtles. Turtles all the way down...

Hi Gavin, I already have an image of it .Will be a big monument rather than a statue. Nissan Shatai HIRATSUKA factory is the place I think . I have visited there once with club members , “ factory tour “ . I want visit there one more time ! Kats

Write an email to Carl Beck and ask him to post it on Zhome.com 🙂 Tongue firmly planted in cheek. 🙂

Just curious. Everything else in my life has gone up except my paycheck.

Thx Alan - all sorted. Resistor was still hiding in plain sight. The drawing made it appear that it was somehow nearby the CDI Igniter, as opposed to clear across the car.

RE 270: if 240Z was truly inspired by "project 270", it does make one wonder if there was a design on the board for a 450cc capacity per cylinder at one point. or I suppose, even more radically, a 300cc 9-cylinder. Kidding about that last part.

Just returned from the body where I snapped these pics of 26th. The shape of the bracket for the master vac hose is not as defined as on 27th. Also, the tool bracket is not bent over like the bracket on 27th.

HLS30U-00027 has the brackets. Pictures attached. I'll see 26th later this morning and take pictures. Sorry for the rusty photographs. 26th is looking much better.

I just want to take a moment to quote this post, and say that the document - marked 'Secret', no less - which Kats obtained and showed us here some years ago, seems somewhat underappreciated. I think it is dynamite. Probably the single most telling piece of official documentation relating to the genesis of these cars I have ever seen. It is, in my opinion, something of a Rosetta Stone... It has it all. Dated 25th June 1969, and with a big 'Hi' stamp (for 'Himitsu'/Secret), it is titled ''270 Kei-sha C/# Dakoku Yōshiki', and it gives us the type designation, purpose, company department destination and actual identity of the first fourteen cars in the project to be given full chassis numbers. First of all, there's no 'Datsun 240Z', 'Fairlady Z', 'Fairlady Z432' etc etc here yet. We know that the project was nicknamed 'Maru Z' (Z in a circle cipher) and was given the internal project number '270 K.K.' ('270 Kaihatsu Kigou'), a glimpse of the terms being used within Nissan just before production. Personally I always wondered where the '240Z' name came from for the Export cars, as it doesn't seem to make much sense ('2400Z' or '2.4Z' might seem odd to us now, but they are certainly more logical) and I am convinced that the '270KK' project code is what actually inspired it. The '240Z' name was a late assignation, after 'Fairlady Z' was rejected for the Export cars. I think the '270' code inspired '240Z' when a name was required at short notice. Secondly, it shows us that - quite logically - 'S30-00001' was the first '270' project chassis to be given a full series identity. 'S30' was the designated series number and the S30-prefixed models of Fairlady Z and Fairlady Z-L were key parts of the family tree. This was how Nissan structured the variants of other models too; a good example would be the C10-series Skyline, where C10 was the series and C10-prefixed models were the building blocks for the structure of other variants in engineering and documentation. Thirdly, and I think this is particularly interesting, the second car to be given a number is described as being an 'HL270' variant. Naturally, with LHD exports being a key part of the whole project, we would expect this to be a North American market type variant. However, that does not seem to be the case. That 'HL270' designation would appear to show it as being a general export LHD variant. So 'HLS30-00001' looks to have been what we might call a 'Euro' LHD type variant. The third car is a 'P270' variant - the 'P' indicating the S20 twin cam engine - and it was given chassis number 'PS30-00001'. Fourth car, first of the 'Ichiji Seishi' cars and destined to be a 'Soko test' car, has an 'HL270U' designation. That 'U' suffix would - according to Nissan's usual habit - indicate a North American market type variant when applied to an 'HLS30' prefixed chassis number. This was 'HLS30-00002'. We then get 'S30-00002', given the designation '270C' (or is that '270L'?). Certainly there's a distinction between this car's designation and the designation of 'S30-00001'. I'm guessing that one is a Z-L (Deluxe) and one is a Z-S (Standard)? That fits with Nissan's modus operandi too. Or does it possibly indicate a factory AirCon car...? Seventh car to be given a number, and the 4th 'Seisan Shisaku' car, is an 'H270U' designated variant. That would mean RHD Export type, and it was 'HS30-00001'. Another 'Soko test' car. So there they are. The first fourteen numbered cars. We are extremely privileged to see a key internal planning document of this type (thank you Kats) and I would say it deserves a thread of its own, and a little more recognition.

More pace car action.....

Lots to love here!

Again, please post a photo from your car. Maybe someone else understands what you are describing, but something is lost in the translation for me.

It shouldn't really matter. Unless you screwed and unscrewed the nuts a few time while you were working on it and the studs backed out. Might be that you didn't have full thread engagement, or maybe the block threads are damaged. Since you have the head off it's probably a good time to really look at how well the studs engage the head. Just more thoughts. The ARP system is smart but the old school head bolts seem to work well on the Datsun engines. Good luck.

A little sedan action with the race queenies!

Are you sure it’s not possibly a 1.25?

I thought that it was for looks.

Just did my '71 tail light panels in December - although not sure if it's the same color shade used on the 280s. Sanded the panels, sprayed Rust-Oleum Ultra Cover Flat Gray Primer, wet sanded, sprayed Dupli-Color Perfect Match BFM0360 Dark Shadow Gray (CX) replaces T299, let sit for a day and then sprayed with Rust-Oleum Ultra Cover Matte Clear. I'm pleased with the results in terms of color and texture.

BIG THANKS ALAN !! You said it all .Your said “ Rosetta Stone “ , I am shivering with it . I am feeling that I want to make a statue of the document , and put your commentary aside. Where is the best place to display? Thanks Alan. Kats

My bill is up 2%, but it will go up more when I increase the value on the 240Z.

Second resistor was sited up on the firewall, kind of hiding behind the washer bottle. If your car is missing it then I presume it was part of the switch to aftermarket CDI system over the factory (Mitsubishi) igniter unit? Here's a scan of the same section of the schematic from the 1969 factory manual, which should be more appropriate for your early 1970 car. Pin #1 on the CDI Igniter is different:

Apologies for the interjection - I'm fiddling with my CDI setup, and in looking at the schematic, I've come across a 0.73 Ohm resistor which I cant find on the car. In addition, my wiring loom doesn't have a Black/Yellow (+12v from ignition) and a Black/White wire (as shown in pin 1 and 7), but rather 2 Black/White wires. Pin 7 is basically powered from the same supply as pin 1, with the addition of a resistor. The car is an early 1970, and this diagram is from 1971. Was there a change introduced, potentially to ease the number of issues with the CDI? These two +12v wires are essentially un-fused (in both cases), and come straight from the amp gauge, through the ignition, and into the CDI unit, so I can see where there would be a "dead short" potential.

Just got some parts back today, blasted and powdered. I think the yellow came out pretty nice. I am planning to powder the hood, front fenders and bumper cover/spaces same color as well. Rest cannot come off so I am asking the shop to just give me the paint code 😀 Next item would be to take out the suspension and powder it all gloss black...thought to share...

Thanks Mark but unfortunately I can't take credit for that trick. I took the easiest route and put an extra rear lid I had and put it up front. @madkaw is the engineer that redrilled the ears. Mine are basically 3 screw 4 screws now.

just like to say that i own the blue 240z hs01920 that was used by hagertys in the 240z buyers guide on you tube

I spotted a brief appearance of a 240Z, near the end of Fast and Furious 9. It looks like cast member Sung Kang's car repainted. I liked it better in white.

@katsthe blue color crank pulley is interesting ! Always thought the where black...
