  1. Thanks Alan , if we don’t understand fully line up of Nissan at that time , we can’t see what was happening with the S30 . Kats
  2. Thanks Carl , yes I think so too , it is not that simple . Reading many books from my book collection , I see these. 1961 Mr.K started a KAKU “ U “ project to let not only engineers but also executives know what is needed for selling cars in the US . Mr. K and Mr . Hara they met already at this point . 1965 L20 six cylinder went on production 1965 Mr. K became a president of Nissan USA 1965 Mr. Matsuo / Mr. Yoshida / Mr. Chiba these styling designers began to study for a new sports car 1966 Chassis Engineers had began to study for a new sports car ( Mr. Kambara is the key person for this ) 1966 late Mr. K met Mr. Matsuo, at this point the cray model which would become S30 was not settled yet . 1967 is the most important year for the birth of the S30 I think . 1967 Feb Mr. Tamura joined the studio and started refreshing the body . Mr.K saw a cray model and said “ I buy this car “ . 1967 Mar Mr .Hara who was a manager of Design engineering and styling section had been watching activity of styling designers and chassis engineers had had decided to start a project of a new sports car . He also believed Nissan can make a new sports car and well sold in the US . 1967 April A meeting was held by production management to set the target of a new sports car. This is the moment of S30 officially became to have six- cylinder engine. A base model is four -cylinder engine, a high performance model is six-cylinder engine. And set the target main market - USA . However this was not seem to tell the styling designer until June , Mr.Tamura . Because he said “ one day Mr. Matsuo came to see my work and suddenly told me “ this car became to have six-cylinder engine “ . That was the summer of 1967 “ . 1967 June 1st new sports car meeting was held and this project was named “ Maru Z Kei kaku “ . The engine has two types , L16 and L20 . 1967 November Mr.Hara had an idea to achieve an approval of a new sports car from executives. I think Mr. Hara did a great job at the presentation. So the answer of the question “What made S30 prototype upgrade to a six- cylinder engine from a four- cylinder engine? will be , “ the meeting of production management held April 1967 “ . As a side note , Maru Z Kei Kaku decided to install a L24 for USA model is July 1968 . Kats
  3. S20 had nothing to do with Yamaha ! If Mr. Goertz ‘ s statement were correct, it would have been meant all two-seater , fastback coupe in the world were designed by him , influenced by him after S30 debut. The designers in S30 design team had already known world’s beautiful sports cars and have taste of those essence. The A550X was never be an model which they started to build . And Mr.Goertz left Nissan way before the project, he didn’t touch / teach any part of the S30 body . Mr. Goertz would never be able to answer for our any single question . Those who want to know about , visit here
  4. Thanks everyone, this is very interesting to discuss. When I home , I will write what I think . I need to review Mr. Tamura’s Letters which describe what was happening when he worked so hard on the clay model . That will indicate when and what made S30 went to have six - cylinder engine. And of course I need to read through again Mr. Uemura’s book , Mr. Matsuo’s book ,and old magazines which were featuring an interview to the “ chief “ of design, engineering, marketing, etc . It seems very difficult to have one answer for everyone ( who is the father , mother , or MVP kind of things . I think each one can have whatever who wants in his mind ) . However we are seeing “what and how they did “ and “ who did that “ at that time . Kats
  5. Thanks everyone, I really appreciate your joining. I realized I had to ask in a different way after seeing everyone’s reply . Like Alan said , seemed there is no correct answer in that choice . I had to specify “when” precisely and use proper words to explain what I was asking about . I always feel there were some key facts of “ how S30 was made “ and those facts were in progress in different people , different section , and they were existing in parallel before they were finally all united . What I was trying to do is ,I wanted everyone to know about the story behind S30 . I thought it is interesting in the part about Nissan executives . ( actually it was not his word , Mr. Uemura quoted from Mr. Hara ‘s book ) I have learned Mr. Hara was very important person who dedicated to making S30 in the early stage . And how do you say , he was a car guy . Mr. Hara also wrote a book , “ Datto San Kaihatsu no Omoide “ ( memories of development of DATSUN cars ) . So , Mr. Uemura wrote like this , ( I will be back later ) Kats
  6. Ok , if your 240Z was born in at or before August 1972 , your car doesn’t need the splash pan . Kats
  7. Hi , I don’t know much of it , as far as I understand is Fairlady-Z ( Japanese model ) series always have it . Not an optional item , it is a mandatory item for Fairlady-Z series even 240ZG . For export model , I don’t know. But except very early prototype used as an example for the service manual and 1973 model year car ( maybe at or later Aug 1972 ) in the US , they don’t have it . Please note the early one does not have holes like you see them on later one shown in the picture . Kats
  8. Hi ,here is a quiz What made S30 prototype upgrade to a six- cylinder engine from a four- cylinder engine? #1. Styling designers wanted a bigger engine #2. Mr. K said “it has got to be a six -cylinder engine for America “ when he saw the prototype #3. Executives in Japan thought it wasn’t a good thing a sedan (Skyline ) has the most powerful engine ( S20 ) in their products . “We have Fairlady ,a sports car deserves a powerful engine . Let’s put S20 in it “ If someone who read the Mr . Uemura’s book correctly,and the book is interpreted correctly ,it is easy to find the answer. I would like to have the English version to see if the book is telling what Mr. Uemura originally wrote . Kats
  9. Hi , good luck on your selling , I was told by Mr . Miyate ( Nissan Shatai engineer ) , he said it was oriented to insurance matter at that time in the US , he ( engineers ) created an access panel for the bulbs each side in order to reduce insurance fee . My 03/1970 240Z still has a non-access panel type rear trim . Kats
  10. I would like to have a new 140 one for my S20 . I have some used 90 ones and 140 ones . Thanks ! Kats
  11. Hi Blue , thanks ! Is there any chance you would trade your 140 switch for my NOS 90 switch 89901 ? Kats
  12. I forgot to put this , my 1972( 12/71 made ) Datsun 240Z . I think a 6kg switch cooperated with a 6kg / 90lb scale work pretty good, it makes me feel happy . Kats
  13. Hi Dan , your data helps everyone a lot , I was also wondering too about the low readings of the oil pressure. My first Z is a 1972 240Z when I was living in Bakers Field CA which always showing middle in the gauge. Then I bought a 1970 240Z , it always stayed very low in the gauge. I remember I was reading Mr. Wick Humble ‘s book and learned my 1970 car was not wrong . Here are pictures which were taken recently, my 1970 Z432 ( shared with all the other S30 DOM & EXPORT using the same 10kg switch , 10kg scale ) and 1970 Datsun 240Z , And 1972 Fairlady 240ZG ( 6kg switch with 6kg scale ) . Just for your reference. By the way , 25070-89910 ( 10kg ) switch is now approximately 200-400 USD if it is a new , S20 owners are seriously want it . Looking at my Z432 , S20 might able to be said it’s oil pressure relatively higher than L -series engine , what do you think of it. Kats
  14. Thanks advise Alan , I need to be nice . I am learning everyday ! YMO is my hero (Mr.K too of cource ! ) , tell me about your joint work with them sometime . Kats
  15. Thanks Chris , I will visit Pierre Hotel again next month on my day-off at NYC . Nice cranes , looks like made of metal , we normally make crane from a sheet of paper . And if you whish paticuler thing strongly for your familly or friend etc, make 1000 cranes and tied them all together , and give it to those people . Alan, yes now I see the picture which is on Nissan 10th anniversary book was edited around the floor ! Now I have a question , why the long hair lady was edited to be a short hair lady ? Like Chris mentioned Japanese men didn't forget their tradition ? Kats Thanks Alan , it is crane , TSURU in Japanese . I edited.
