Steve, You sold L24-060039 / 9X04D, I hope the man who got the engine from you will be informed about this thread in some day. Originally, we were confused why 060039 got E31 on the block, and I am sorry I was very suspectable about your engine.I said it should be P30 here 6 years ago. How about this, at Yokohama engine factory in mid or late 1971, a NOS machined block but did not have a serial number was found in their warehouse,they simply put on the assembly line... Just my thought. Just for an example, PS30-00347(12/1970) got S20-000074.Normally this low serial S20 to be installed Feb or Mar 1969 Skyline GTR. kats

Thank you Alan, I did not think about machining, it comes before assembling, that is right. A specific number is needed to identify each one during assembling such as engine, body. So, serial number must be stamped before the assembling. For the engine,after machining , the block got the serial number, it makes sense. Can we extend this way of thinking to body serial number? When a car (body) got a serial number?After welding?or painting? or ... People who are interested in this(including me) should go to proper thread. Thanks Alan, the scenario of S20 for Z432/432R , I agree with it very much. kats

Hello Steve, I am now very positive that your engine block is truly 1969 made with assembled in some 1971 ,L24-060039 is a real serial for that engine. There is a long long time gap between 1969(Nov) casting and 1971 assembling.But I think it could be,like Carl told us about in a environment at the factory.(Thank you Carl recap) The casting is first, then assembling.It could be happened to Steve's engine. 1969 casting block has 1971 serial number .It could be. But vice versa never ever happen.I think. kats

Thank you everyone, Mike,could "X" indicate Oct ? 9X04C and 9X04F they are making me think of that. More earlier L24 has 99##@ and next groupe would have 9X##@. I tend to think they used X for Octber, Y for Novenber, Z for Decmber. I am waiting some reports about the casting code which has Y and Z. The casting craftman did not want to add an extra digit in 1969? How about this,let's say an block was made on 1969 Nov 11th,and it has "I" at the end, The casting code could be "91111I" Is not this easy to be mistaken Jan 11th or just dificult to read out is it? I think there will be "9Y11I" ... kats

Hi Carl, Thank you for telling us your experience, I can imagine how manufactures were doing in the factory. Yes , the L24- 107 , let's find out what the casting code is. Seems to me 9 2 1 2 4. And now I remember L20 block has E30 on the block for an early S30. Early L24 has E31, yes they are different from begining of casting. I believe a nice siliver 1969 Fairlady-ZL(L20 engine) still owned in the U.S., I want to see its casting code on the L20 block. kats

Thank you and That is right, Carl The GTR made a debut Feb 1969.What I was surprised is why Dec 1969 Z432did not receive Nov or Oct S20? For me it is very interesting Mar S20 is way before for Dec Z432. My explanation skill is poor, sorry always. I hope more owners put information here, it is fun to see compare chassis and engine number with casting code .Especially owners in the U.S. you all have build date tag,that will be more fun. I think L24 was first applied to 240Z,but relatively they are big number (like L24-002xxx) as a begining of production. Is it possible they are same block L20 and L24? After having a block,were they boring for 2400cc or 2000cc then stamp "L24-00xxxx" or "L20-xxxxxx" ?Can we see something from reading casting code of them? :) kats

Hi, Today I show some car's (Z432) casting code on the engine block.They are not L-series engine, but they will give us some good points. They seem to me they are telling exact day of when they were made/or born. The way of casting method looks same like L-series engine in 1969, but I think after 1970, S20 engine is little bit more specifically telling date. My Jan 1970 Z432 has S20-000884, the code is 9 3 14 56.(1969 Mar 14th, what does 56 mean?) Mr.Watanabe's Dec 1969 Z432 has S20-000850, the code is 9 3 18 ?? (1969 Mar 18th,last 2numbers hidden by oil and dust) I am surprised S20 engines were made(I should say "Casting", may not be "stamped serial") well before Z432 went on the assembly line. I checked some S20s for sale at the Mr.Moroe's shop S20-001290, the code is 9 6 24 37 (1969 Jun 24th, what does 37 mean?) S20-001839, the code is 70 5 27 21 (1970 May 27th, what does 21 mean?) S20-00????, the code is 71 4 2 2 (I for got take a picture of serial number) S20-002615, the code is 72 3 6 23 (1972 Mar 6th, what does 23 mean?) These are just my guessing.I think casting code is telling the day, then serial number was stamped. So, sometimes they are not in sequence among them. I think it is possible I will find a 1969 Jun 18th(my birthday) S20 engine,if I am lucky. Must be somewhere. What do you think of it? kats

Yes Alan, This summer in Japan is unusually hot.It is like everything is melt down if you leave it outside!! 35 to 39 degrees of Celsius is common everywhere in Japan this summer, I guess it is hotter than Hawaii. Close to Las Vegas? kats

Thank you Alan, How are you doing? When are you coming Japan next? When you come,please let me know,I have some for you. The Portuguese market , now I understand. kats

Hi Mike, About the writing on the rear metal panel,I agree Eiji-san and Alan. Upper portion of the rear panel had got the burr, so they needed be smooth out. Nice car,Mike! And I have got an used oscillator for you, but it is really old and I do not know if it works or not.Anyway it is a small gift for you,I will send soon. kats

Hi, I have just been amaized these Kanjis. Some are the name of person and some are the numbers.And some of them is just meaning-less.I think they wanted to have fun when they were in a production line. I guess they were doing it with fun, having an imagination of when the oversees owners or mechanics would disassemble dashes in someday, with seeing unusual characters then they would try to understand what they would be. Fantastic:classic: kats

Hi, Here is a 1972 240ZG, this MAROON car is a very good one, very original car. This car has a factory installed(in a production line) air conditioning system. Did you know Fairlady-Zs were available air conditioning system from the begining of production? I mean from 1969 the system was available but not available for PS30(Z432) nor S30S (Z) In this system, an evapo is located in the dash,very smart.The control panel was a special for the air conditioned car.Most selecting valves and flaps are controled by vacum system. And about the fog SW, in 1972 Fairlady-Zs,the far right is a black blank plate usually.If an owner chose a fog lamp system,the SW 25370-E8700 should be installed there. But, but, I have never seen 1972 fog lamp SW nor fog lamped car. I have seen some 1969/1970 car have a fog lamp SW,but most of them do not have fog lamps, I do not know why. My Z432 have got the fog lamps and the SW,this is the only one I have ever seen the car have real fog lamps. Fairlady-Zs do not have a choke light nor seat belt warning light like U.S. 240Z.Fairlady-Zs also do not have a steering warning system(buzzer and SW) Please enjoy pictures. Thank you kats PS;Enrique, the pictures of wiring for Fairlady-Zs will work for you? Just in case.

Hello Thorsten, I am sorry for this late, thank you so much and you are living in Germany! I am very interested in your car, is your car made for Germany? If so,I think your car has lots of interesting parts to compare with my U.S. 240Z. Alan told me onece before,Germany 240Z sometimes has magnesium wheels e.t.c.How about your car:) About the build date, we too, we do not know yet exactly. Someday we wish we can find more precise information from NISSAN, that is everyone's dream. I want to know when my Z432 and 240Z had dipped in the swiming pool and when they have got their engines and when they were checked out from the final inspection e.t.c e.t.c.... About chassis numbers for Japanese S30 i.e. for Fairlady Z series, they are S30 and PS30 when the factory started making in mid 1969. Late 1971, HS30 was available for Japanese people,at this time, chassis number HS30-10001 was the first one for Fairlady-240Z(or 240Z-L or 240ZG). So, no HS30-0000X or HS30-0XXXX were sold in Japan. This is my thought, I do not think there is HS30-09999.How many HS30s under #10000 were made for the world? And I do not know why, in 1972, NISSAN started chassis number HS30-100001 for the car. How many HS30s between 10001 and 100001 were made for the world? Here are some numbers,they may not have test cars or racing cars. S30(L20 engined) 1969 : 00001 to 00953 1970 : 00954 to 04330 / 04501 to 04504 1971 : 04505 to 08328 1972 : 08329 to 11109 / 100001 to 101613 1973 : complicated!(due to model change but same "S30") HS30(L24 engined in japan) 1971 : 10001 to 10436 1972 : 10437 to 12045 / 14001 to 14801 / 100001 to 100800 1973 : 100801 to 101537 / 102001 to 103262 PS30(S20 engined) 1969 : 00001 to 00072 1970 : 00073 to 00345 / 00401 1971 : 00402 to 00513 1972 : 00514 to 528 / 100001 to 100006 1973 : 100007 to 100008 Thank you, kats

Hi Enrique, I am happy that you still have the SW.That was winter 2002! This thread made me post some pictures in "Z432 vs 240Z" thread,please look at. kats

Sorry Ian, I misunderstood what you are saying. I do not know Mr.Kimura was doing design for A550-X with Mr.Goertz. We can not say "that would never happned" until we hear from Mr.Kimura. Or do you know already something about that? kats

Hi Ian, It could not be happned ,the time sequence is CSP311 came first then A550-X. When Mr.Goertz hired by Nissan,CSP311 styling was mostly completed. He cahnged CSP311's C-piller design,but that is an only job by him. kats

Hi Alan, I did not realize about the bulge, yeah, looks slightly shorter. I need some good angle shots to compare them. This is a Z432, I agree Alan. But I do not know the chassis number. I do not remember we talked about this before. A few years ago I posted some threads to "CLUB S30" in Japan about Japanese S30 brochure has some S30s with unusual hand-made emblems on bonnet and C-piller. Did I posted here before? kats

Alan, I think the emblem on the bonnet is placed little bit far from the front end, do not you see? kats

It is very interesting,thanks! About the 3rd ad car, Does anyone find something unusual on this car? kats

Thank you Kathy & Rick, I am glad that you enjoyed this thread, you have wonderful 00013 and 00171. I saw a new year postcard from Mr.K to someone there is a 240Z it's side sill painted black. Is that car your HLS30-00013? kats

I got you Mike,thank you. Two threded holes on the basement near the horns are for the oil cooler. If you install the cooler, you need to have extention brackets for the horns to prevent interapting each other. kats kats

That is wonderful Mike, By the way What does threaded mean? Could you exprain another word for me, it means the hole with a nut ? kats

Hi Mike, That is interesting ,I do not know how the hole is used . I see the hole on a 1973 Z432 ,the picture in my laptop. Also I am curious about holes for the oil cooler, I think every S30 has them, could you check your 1969 and 1972 car Mike? Here is a link to Mr. Takeuchi' s blog about his 1970 Z432-R you can see pictures of the oil cooler. http://s30pzr.blog50.fc2.com/?mode=m&no=229 kats

Hi, I reviewed about production number which we talked about some long time ago. Here I posted again the data sheets which I have got from Nissan Shatai when I made an interview to the test crew,Mr.Uemura and Mr. Osawa. It is very interesting to see those cars were given numbers in sequence. To cross reference these data,we can see when each car were made . These are FACTORY PROTO TYPE, 05/69 No.1 = S30-00001 Nissan Shatai (test drive) 05/69 No.2 = HLS30-00001 Q21 (production factory study) 06/69 No.3 = PS30-00001 Nissan Shatai (test drive) These are PRIMARY PRODUCTION PROTO TYPE, 07/69 No.1 = HLS30-00002 Nissan Shatai (test drive) 07/69 No.2 = S30-00002 Nissan Shatai (test drive) 07/69 No.3 = PS30-00002 K11 (registration) 07/69 No.4 = HS30-00001 Nissan Shatai (test drive) 08/69 No.5 = S30-00003 K11 (registration) 08/69 No.6 = S30-00004 F45 (K31 spare) 08/69 No.7 = S30-00005 F45 (K31 spare) 08/69 No.8 = PS30-00003 F45 (K31 spare) 08/69 No.9 = HLS30-00003 E81 (service; service manual? kats) 08/69 No.10 = S30-00006 F45 (for press/media) 08/69 No.11 = PS30-00004 F45 (K31 spare) Mr.Uemura and Mr.Osawa told me the two test cars were PRIMARY PRODUCTION PROTO TYPE #14 (HL270U) and #15 (HL270UA this car has an automatic trans). As you know, 270 is a code number for S30 when it was in the factory. There are only two rooms for Export S30s in 09/69, this month started making from No.12... So, think about PRIMARY PRODUCTION PROTO TYPE No.12 and 13 with regarding Mr.Uemura and Mr.Osawa's comment, No.12 and No.13 could not be Export model. We can see No.14 is HLS30-00004 , No.15 is HLS30-00005 according from these data and test crew's comment. Just information for someone will be interested in. kats

Hi Mike , I am wondering too, the engine serial number looks painted white, very interesting. I am not for sure other Nissan cars have L24 before the S30, but maybe S30 is the first one as a production model. So L24-107 is interesting considering early 240Zs having #2000 more. Hi Dan , I did not know the difference,your eyes are 20/20 still I think ! kats
