Hi Alan, I didn’t have this one , so I quickly bought the one ! Thank you. Today I found some new YouTube of Z432-R , they are very interesting to see. Both cars are not well known in Japan (World wide too) . But I believe the one in the Sunday car meeting must be the one which was restored at TA -Auto , Ando-san’s work . I visited several times and watched the progress, that was very interesting to me. Alan might see it too, might not you ? And the one is now restored in progress is now very “ hot “ in Japan. Mr. Saito ( owner and the mechanic) has got the car almost 20 years ago without knowing it was a Z432-R because the car was pretended to be Z432 . It had Normal seats , normal center console , aftermarket steering wheel, and painted red , etc etc. After stored it in his garage , he found 100 litter gas tank ! He suddenly realized it is Z432-R , PZR , PS30SB . Saito san has been showing his working progress on YouTube, his channel is now huge popular in Japan, but he never mentioned the car is Z432-R. He seems that he doesn’t want people get so excited about it and send him a lot of questions and comments which make him bother . But we already know the car it is ! Kats

It is mysterious! Why was the side marker deleted ? Just put a new one certainly mast have had been the easiest way . Kats

I am glad that you like it, and Alan , this is the magazine , “driver” issued 5th February 1971 . This magazine is for general people, family car to sports car . Kats

Thanks Alan ! “8D-420” , I really love it . The oil filter is red , and inside of the bonnet is also red , interesting! Kats

Hi , is this car the same car of Auto sport 1/71 ? Kats

Here is my observation . The picture of a green car , thanks Gavin . Kats

Thanks Alan ! Your input made me go through all the S30 variations. I think the mystery third clamp , the captive nut might be for the bigger battery flame. Japanese S30 series cars were able to have bigger battery for cold area . Looking at the picture of the Australian magazine, the RHD export model , the battery is bigger one just like the one for the LHD model . And also I come to a conclusion, up to around 1971 cars have only three bolt on clamps for the battery cable , after that , they became four of them . I looked up the parts catalog 1969 / 1970 / 1972 /1974 both export and domestic. The description says they are three of them in 1970 version but they became four of them in 1972 version. And this is my guess , Z432 and Z432R would never use the one at the underneath of the choke cable because of existing of the stand - off bracket. So , they are two of them up to 1971 , then became three of them . So , back to my first question, 1974 Fairlady Z series parts catalog says three for Z432 , four for all the other model . That is correct! Kats

I have something to be clear, for Z432 , parts catalog says three bolt on brackets, four for other models. So , looking at my car and PS30-00055(Dec 1969) , both have three welded nuts which seems serving for the cables on the fire wall . Then I thought I need to put #3 bracket just below the choke cable grommet (please see my post above). But , I am feeling something uneasy. Both cables should be clamped by the stand -off bracket, shouldn’t be? My idea for the negative cable routings doesn’t look right day by day .Nissan engineers intended to clamp both cables didn’t they ? And seeing the red PS30-00055 and other Z432 , the #3 nut looks never used . Even my Z432 would have never used it. So , why parts catalog says three bolt on brackets ? Interesting! Kats

I reviewed my Z432 engine room, I found the battery cables we’re going through over the top of the bonnet catch basement during restoration, but I changed it at some point without any knowledge. And still now it is very fun digging into originality, I want to see a lot more examples to nail it down. The picture from the Service Shuho shows the car doesn’t have the stand -off bracket , instead of that , there are two clips which is used also for L-series engined car. I can’t do the same thing because this car could be a very early one like production prototype cars . But I can see what is needed for S20 battery cable routings from this picture. As you can see , S20 requires different throttle linkage which is obstructing battery cable routing for L20/L24 engined cars. Kats

I hope you find the solution soon ! By the way , I have heard that NAGAI discontinued making their MDI tailored for S20 in2019 but there is another manufacturer produces CDI /MDI just bolt on to the S20 . I don’t have knowledge of aftermarket ignition system, so I have to stick with stock system . Kats

Hi , I don’t know much about GT-R , you are so lucky that you can compare your Z432 with your GT-R ! Stop pulling at 3000 rpm , ummm, my Z432 was terrible once because the gas tank was full of rust . Or I will check the ignition system , do they have the same igniters which is provided from Nissan original system ? The original Mitsubishi igniter box might not be working properly if the car doesn’t pull right performance . I had it six of them in the past , two of them were not working properly even they were NOS when I bought them. The air box has six trumpets in it , and it’s length is not so aggressive I think. But it is very good for street driving,Nissan engineers well considered of it . Your GT-R has different trumpets then it’s length matches for much sportier driving , then your GT-R go faster than your Z432. What I am feeling “ superior “ about the Z432 air box is, Z432 has the air filter box out of the engine bay , in front of the radiator. GT-R has it in the engine bay . Z432 ‘s S20 can inhale cold fresh air than that of GT-R , I believe it slightly provides additional output for the S20. But on the other hand , air flow is restricted and loses smoothness by the air box , so free air flow VS cold fresh air , please someone enlighten me ! Kats

Thank you so much Alan, your inputs are perfect. I need to look how my Z432 has them . The small bolt-on cramp should be three for Z432 , four for all the other RHD S30 series . Kats

I really love this kind of conversation, thanks!! I want to write a bit something about the cramps, when I come back home. I like to see the work of your Z432 , please post anything anytime here . I am learning new everyday and it is very interesting. Kats

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

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. Kats

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. Kats

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 . Kats

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 . Kats

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. Kats

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. Kats

Thanks everyone, I ran out “like button” ! I need a jet fighter aircraft, I want to reach my room and show what I have for you, now ! Kats Oh , S30-00002 has air-con too ! You can see the beautiful check valve junction, one of the coolest looking piping and connectors among cars around 1970 .

Thanks Steve , you helped Matsuo san for the presentation, must be wonderful time for you ! Yes I would love to post pictures here when I am home , they are so interesting to see I guarantee it. I have heard it was not easy task to have the system in dashboard because it was so small room for the system. Matsuo san or Uemura san ? Told us Toyota 2000 GT couldn’t have it in a dashboard, but on the rear deck behind the two seat backs, a big box dominated the space . It was not cool at all . 260Z and 280Z have a factory installed air-con system, I am feeling those system were updated version of Fairlady Z series air-con system from Oct 1969 to Aug 1973 . But basically the same, both systems use vacuum power to move the inlet doors / airflow direction flaps . Kats

I am also thinking about “Nissan genuine air-con “ which was offered only in Fairlady Z series . I assume no Datsun 240Z was offered it from the factory, but look at pieces of the components, I am convinced that Nissan engineers were considering it would have been also available for LHD export market . I have been collecting parts for whole system and mostly done. Some parts are just fit into the existing components and some other parts needs just a little work . That is why our LHD 240Z has some “ not used “ brackets on the heater box , pre-cut on the fire wall insulator pad . So , “PLS30” with a factory in-dash air con system , a combination of sportier performance with comfortable cabin would have made the car to be a gorgeous GT . Surprisingly S20 has a special crank pulley for air-con with a part number E4200 ( Z432 oriented) , but I can’t see other air-con parts specifically made for Z432 . Nissan never officially offered air -con for Z432 . But I have seen some Z432 have the system using from Fairlady ZL system . In 1970 , it could have been around 6000 USD ( based on 1 USD for 360 JPY) , no more bargain price? What do you think? Kats

Thank you so much Alan for sharing a cool picture! Kats

Hi Ian , what a surprising thing this is ! I was going to miss it if you wouldn’t notify us . This is the earliest version as it doesn’t have a small pipe which is sticking out from the rear top surface, for the blow-by tube from the valve cover . A buyer need to source a Darin plug and a tube at the rear bottom, and four pieces of brackets ( three for the long heater outlet hose across below the three Mikuni carbs, one for the fuel supplying tube from the strainer).
