Kat,

Nice S30-00002

Cheers, Kirk

 

Hi Kirk , thanks! Was your 70 Fairlady first purchased in Aomori ? If so and if it doesn’t have an A/C , it makes sense to me because northern Japan people didn’t need an A/C especially those old days . 

Or even hotter regions, factory A/C was 200,000 JPY , it was certainly expensive for Japanese people at that time . Z-std was 930,000 JPY , an A/C costs Nearly 20% of the car itself.

Does anyone know what happened to that car? I recall seeing those photos of it on this site at least 15 years ago. But no follow up on where it is now?

Hi Gavin, we need to look at the car soon , I am surprised it was such a long time ago ! 
When omicron goes away , I will ask my friend to see the car in person. A few years ago he said S30-00002 was still there and covered just like the pictures.

Hi Kats. Do you have a copy of this 1970 Fairlady Z air conditioning manual? It notes the air conditioning system can't be used on the PS30.

Hi Mike, where did you get the book ? I am so surprised that you have this copy which might be one of the rarest things I’ve ever seen. 
( I had to buy a set of six books to buy just only this copy for 100000 JPY! I sold the other five books for 60000 JPY, so crazy expensive 😰) .

Anyway , we will see how wonderful Nissan factory A/C for S30 series is . And interesting to operate!

First , we need this face panel to have it in our cars.

Kats

PS : As you mentioned above, this A/C can’t be installed on Z432 series (PS30&PS30SB) , it is described in Forward. Literally, no you can’t. 

But That doesn’t mean “never “ because the system was designed for L-series engined car , however piping and assorted parts under dashboard area are nothing changed. So it is possible with some hand craft works for engine Bay Area .

All the things in the system can be installed as they are , except compressor mount bracket, condenser ( need to be much smaller to avoid the air cleaner box and the coolant reservoir tank ) and the FICD (it was only designed for L-series) .I don’t know why Nissan quit making A/C for  Z432 , but the A/C pulley for S20 is a good souvenir for us .

Hi Kats. Interesting that it is a rare manual. I got it on Yahoo Japan a few years ago and it wasn't very expensive. I got lucky I guess.. My 1970 Fairlady Z had an aftermarket AC system added in Japan before it was brought to the US in the mid 1970s. I wish it had the factory AC system. I'm sure that was a very rare option due to the cost. Do you think S30-00002 had the AC system when it was built? I recall a thread about that car years ago that said it had some later modifications on it when it was found. Maybe used as a test car? Was AC available as an option in Japan from the beginning of production? I believe the AC manual has a publishing date of 7/70 but I don't have it in front of me right now.

Hi Mike, that is a good question, we can think the Factory A/C was available from the beginning, I mean from Oct 1969 for Fairlady Z series. Because, the  very first catalog  listed the A/C as an option for S30 (Fairlady-ZL ) , and the Service Shuho ( service bulletins)which  Alan posted is dated at Nov 1969 .

Mike , I was wondering too , the book dated July 1970 . Why ? 

Then I red the Forward again . It says “ the car S30-C which is designated for this A/C has been installed the system in the assembly line . However, cars other than S30-C are going to have the A/C as an option, then installation must be done at dealerships. So please refer this book for your installation “ .

This leads to me a picture in my mind like this , when S30 cars were introduced A/C system was not so popular. But gradually people tended to have it for their S30 ( Fairlady ZL ) after purchased . Even some people would have wanted on their S30S ( Fairlady Z ) or PS30( Z432) which were regarded as cars they “ can’t chose A/C “ on the catalog . 

To accommodate those cases , Nissan issued this book making the installation easier for dealership mechanics. I think like this , what do you think of it? 

About S30-C , I studied a little bit . 

In the Service Shuho , we see Nissan gave a specific variation code for the car equipped the A/C on S30 , that is S30C ( C stands for air-Con I think) . Type code ,classification code , these are the matter of Japan Motor and transportation ministry. And those are interpreted into specific numbers and they are indicated on the registration/certification paper . A variation code is Nissan in-house code thus  not shown on the paper . Having the A/C in S30 had nothing  to do with Type code and classification code , so no need to declare for amendments of the paper. ( if you swapped Engine, or changed length/ width etc that is going to be a subject of the amendments )

About S30-00002 , I don’t know when the car had the A/C, I am very curious about it too .

Some good and some bad , 

I found the both tail lights are an early one (220-24152) which don’t have markings on the lens corner like other later ones . And they can be beautiful after some cleaning.
 

The fuel tank is full of rust , needs to be replaced or cleaned.

Hi Kats,

Reproduction fuel tanks can be bought here.

https://s30.world/

[kats]

Thanks Gavin, yes their products are outstanding! I already have one for Fairlady Z series  in my hand , looks exactly as original from any angle. I just want to re-use the old dirty tank , but it is possible to have a new perfect reproduction tank for HLS30-02146.

If my spare S20 goes into my HLS30-02146 , these racing parts will be assembled in the engine.

The highlight of these parts is the Nissan Works titanium con-rod which was not listed on the sports option catalog . I don’t know this set of six con-rod was raced in a Works  car or semi-works (private ) car , or even not assembled . 
Some one says not good for daily driving, because it primarily was for one chance victory , Alan will know more about it, please tell us what you know about .

I sometimes feel I don’t want to assemble them because I will never see them again one by one after the engine completed.

Kats, make sure to mount a dash camera with external microphone so you can capture the noise the engine makes with those rods installed, if you go that route.

Looking at Z432 battery cable routing.  Mine has clearly been monkeyed with, so I want to fix it.  Based on some stills I can see from your car, Kats, it's different from what a standard S30 RHD is, in that your negative is routed along the top of the cowl (where the positive would be on an S30), and the positive is right below it, and going through the hood release latch mounting.  Is this actually how they routed it? or perhaps I'm looking at older pictures of your car? (btw, that how the previous owner routed mine, but the number of zip ties used make me think that its probably not factory.)

Stock PS30 battery cable routing should be very similar to stock S30 and S30-S battery cable routing for cars made during the same period.

The two cable run from the battery, along the firewall at the same level, over the top of the bonnet/hood catch bracket, and then turn down towards the bellhousing and starter motor - with their last holding point on the firewall being the dedicated stand-off clamp which is quite similar to the Mater Vac hose bracket. Small bolt-on clamps hold the cables to the firewall.

I think people started routing the cables through the catch bracket because it acted as an extra guide, and perhaps looked a little neater. Strictly speaking, it is not correct.
