Thanks CanTechZ ! Here is a glove box collections, white chalk marking is fun to look at . Automatic has “トルコン(torque converter) “, Fairlady 240ZG has “H-H “ ( HS30H ) , Z432 has “ PS30” . But you see SP30 , that is definitely a mistake ! Kats

I was wrong about this , normal Z432-R has the same spring rate as Z432 , just free length is shorter than Z432 . Z432-R is 80 kg lighter than Z432 . To have equal dimensions as a variant of S30 series cars ( floor clearance hight is the same as Z432 , ) , the springs are shortened I think . I am talking about this car , a plain , raw , ready for building a race car for your own .From Motor Magazine April 1971. Kats I probably can’t use my set of PZR springs because my Z is not light like PZR , the hight will drop slightly. I love Higher posture like Safari car .

Wow ! Thanks, that is what I have been wondering and waiting to see . Fairlady Z Air conditioner manual said “ you need to buy 68600-E4102 glove box assembly for cars up to S30-01629 . Cars after S30-01629 have already 68600-E4102 “ I was wondering what is the difference between them . Now I can see the one you showed us is the early one, and later one notched both sides for better spacing of the Aircon system . I can see the attached picture excerpt from the Aircon manual , we see notched both sides , this is 68600-E4102 . The ducts from the both end of the dashboard wrapped with thin sponge sheet , and ducting around evaporator need more space I think . By the way , LHD 240Z has the same glove box? Kats

Hi Roo , from this picture, I see one hole at the rear suspension transverse link member , is that what you intended to point out? This hole is not always there , I believe I only saw one PZR except Takeuchi san’s PZR in my experience. There is no specific part number for the transverse link member. So probably one-off hand made ? And also Takeuchi san put on sports option adjustable suspension struts . If we judged this car at stock class , this adjustable suspension would have been regarded as a modification because when the car was assembled , that suspension was not available on a sports option catalog . Instead of that , a fixed type struts was available for PZR ,this one could be “ no-deduction point “ if judges know what they are . Originally PZR has normal struts which are shared with PZ for the front , shared with all the other S30 models for the rear when it left from the factory . Just springs are different. One surprising thing is , those PZR normal springs for normal suspension struts ( PZ & PZR front struts is -E4225 , rear struts is - E4125 ) have softer spring rate . This is very interesting! I will be back later . Kats https://m.youtube.com/watch?v=HR2bRaiPADc

Thanks , so as yours ! Please feel free to post anything here anytime. Kats

Hi Roo , I can’t tell anything unique of the rear suspension from those pictures above , I am missing the uniqueness! Kats

Hi SpeedRoo , good catch ! You are the winner. I attached some more better shots from a Z432-R at Ando san’s shop . Note a metal tab for the switch wiring inside of the tunnel. And the rear gate , PZR has different one (PZR for Works (early) used FRP rear gate , for road going used steel rear gate) . Ando san told me something about inside of the rear gate. I will tell you about it later . Kats

Thanks Alan, seems to make sense to me. Light weight front fenders are so special. Takeuchi san and other PZR owners usually complained about people tried to put their fingers on the fender to push down and see how the metal is flexible for recovery from bending. At car show , Takeuchi san couldn’t leave his car for lunch . That is an old story I think , nowadays nobody will try to do that , everyone knows how those cars are expensive today . Kats

Here is a good shot , what thing makes this car a Z432-R ? Kats

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
