I amended, I am glad not for me , for this thread made by everyone here ! Kats

Thanks Mike , it is a great help . Don’t you think the parts number is something wrong , do you ? Please see my corrections. Anyway , the number E4103 is for the “ brown “ seats , and this doesn’t mean either the one which is kept by Mr. Sudo or the one can be seen in the test car . We actually have the tan seats as “ brown “ E4103 , don’t we ? Jason240z , I am so glad that you said that to me ! Kats

Thanks Blue and 240dkw , Yes the car definitely was the test vehicle ( without chassis number ) carried a lot of recording machine for data collection. And you see the brown interior trims which was never applied to the production model . I think the Naugahyde which Mr. Sudo has could match that brown interior. Nissan actually planned “ brown “ trims for Fairlady Z series in Japan from the beginning of its production , but none of cars has that brown trims , there might be some reason that the brown trims were never applied. Only parts numbers for the brown seats are still listed in the Fairlady Z series parts catalog. This is one of the ridiculous thing in the catalog for everyone ! But not only planned, Nissan ( or Ikeda Bussan : seats company ) actually placed an order for the brown one to a Naugahyde manufacuturer for the production . To assist this story , Mr . Sudo has an interesting experience with the brown Naugahyde . One day he finally nailed down the exact Naugahyde which is used for the S30 seats , then he placed an order for the manufacturer with telling them that “ I am going to use it for S30 seats “ . What he has got is , that brown Naugahyde first , then black one later . Those two both have exactly the same textures on it . That is why I think the brown Naugahyde which Mr. Sudo has is special , it was planned once but been never applied . Kats PS : Can someone list the parts number for the Export S30’ seats “brown “ ? I am away from my home , I just want to compare the two of them. Here is the Fairlady Z seats parts numbers from 10/69 to 03/72 .

Thanks Mark Maras , Chris , and Alan .You all are correct yes , I think so too. What I wanted to say is, look at this please . Excerpt from a movie by Nissan . Kats

Blue, I did it before ? OK . And the silver car has a chrome Z quater emblem , and does not have a dove tail at the door , I see some super early cars do not have the dove tail , this can be a clue for determing the chassis number . Chris, I think I have visited the ball room in Christmas 2006. I just wanted to feel atomosphere and imagine an excitement when the 240Z was on the display . Yes , it was small than I expected. Kats

Hi , I couldn’t stop myself posting this, here is a quiz , what kind of material is this ? And what is it for ? Mr. Sudo has this , it is unbelievable. Kats

Hi Blue , did I post this before ? Kats

This is very fun to read , we can gather information what we have got so far and we will see some interesting facts . When I am home on Sunday, I will check the LA auto show held in late 1969 had a silver 240Z , with C pillar emblems , without D emblem on hub caps . I guess the car could be different from the two test cars in the North America during Oct to Dec 1969 . Kats

Thanks Blue !

Thanks Alan , Blue. Last week I took my blue 240Z for a drive to Tokyo , to have its seats refreshed by the craftsman Mr. Sudo . As I told it here before , the blue seats were restored by him in 2003 . This time I want the seats look just like new again with replacing worn out pieces . Mr. Sudo is going to replace vinyl pices only where worn out , this is my request . He gave me the extra vinyl when he did the blue seats , but the vinyl is not enough for making a set of whole seats . Also I don’t think they need to be replaced whole thing as they are almost perfect in most of part . The seats were finished in later “ slim seat back “ style , I have been dreaming about having early “ fat seat back “ style in this blue vinyl. This time Mr. Sudo is modifying them to fat seat back style using minimal amount of the vinyl, I am really excited about it , I can’t wait to see it when he completes the re-upholstery. Here are some pictures in progress. I will be able to show you the seats done in the end of this April. Kats

Thanks Blue , nice findings. I might be curious if the car used in the service manual would be HLS30-00013 . A lot earlier car could be used for the manual , couldn’t it be ? Kats

Hi Gavin , the motor was bought by a used car shop which is located near my house . I visited and saw a mechanic was trying to install the engine into a Fairlady Z (L20 model ) . Kats

This is what I saw on Yahoo auction some years ago , this engine is definitely pulled out from the car , PS30-00061. It is mounted on the big frame as if it was displayed in a museum . This was cheaper than that of current prices . Kats

Already 2 200 000 JPY ! No way , I am out . I now realized its engine and transmission, and R192 diff as a set were the ones which pulled and sold on Yahoo some years ago , they were very good condition. I wondered where was the body , but here it is ! Kats

Hi , a 1969 PS30-00061 is now on sale at here , https://page.auctions.yahoo.co.jp/jp/auction/w303997991 No engine , no transmission, but a registered paper comes with this car . If the price stayed lower , I would have thought to bid . 880000 JPY currently and not meeting a reserve . Kats

Alan , thanks for telling me the point , the compression ratio is the matter . I think the spare head will definitely need to be shaved 0.5 or 1.0 mm , as I don’t want the head to have any things that make it higher compression ratio , I need to think about a thicker head gasket ? Or enlarged combustion chamber ? The Z432-R racing manual is saying “ the compression ratio will be 10.1 to 10.3 when using a racing pistons. You will have little more extra power if you make the compression ratio exceeding 11.0 . However , with regarding fuel , 100 octane currently used , it is safe for the engine keeping the ratio within 11.5 “ BTW , STD piston’s ratio is 9.5 with a STD 1.2 mm head gasket. And , I am worried about the valves may hit the high intrusion crown pistons . And I have read about an article which says titanium is expanding when heated , so does the conn rod have to have bigger gap for the bearings as well as bushing on top ? Kats

I am waiting for getting a set of racing cam “8L “ and adjustable cam sprockets which were also used in racing cars from my friend . I won’t be able to come by titanium valves , special springs etc , so looks like I am done , I am satisfied at this moment. I just hope my spare engine project going well , I don’t race , I will be happy if the engine is just running. I set the goal , build the spare S20 engine like someone who race but not enough money to buy complete set of racing parts . I will tell you later my feelings when I run the engine. Partial racing parts installed ! Kats

A set of parts , and Z432-R racing manual. It is said that STD pistons are casting made , on the other hand racing pistons are forging made . Even this page doesn’t mention about titanium conn rods , it is the sign of “ titanium conn rods are specifically made for factory racing “ isn’t it ? Kats

Hi , I have got a set of high compression pistons and , titanium conn rods . They are meant to be used in a racing car ( GTR or Z432-R), factory team or private racer . I try not to expect too much , but I think these parts in front of me are real period correct parts which related to either Nissan Murayama , Oppama , Omori racing factory. From early 1969 to mid 1972 , those factories were very busy every day for developing racing S20 engines . Engineers and craftsman tried so hard making new cams , pistons , etc , testing them , and installing them in racing cars .Even heads as well as blocks , almost each race has new parts . Some parts were the same which were sold as sports option in a catalog , but many of them were not listed in a catalog , factory or some private racer only . This titanium Conn rod is the one , not on a catalog but used in racing. This piston is the same , looks slightly different from others . Alan , could you authenticate these parts ? And please tell us more about racing back in those old days. The titanium conn rod is 474 gram , the std conn rod is 710 gram , I have heard titanium is lighter than steel , it is about 2/3 . So , looks like I have got a correct one ! Kats

Hi Mike , we will meet soon , I have been to Fuji Speedway last week to see a racing Z432 for some laps for setting and testing . Here is an old picture of PS30-00013 at Fuji Speedway back of the paddock might be shoot in late 1969 or early 1970 , and a picture of my Z432 in 2019 ! And a movie . Kats

Hi Jim , yes the can which he has in the video is the clear coat . We used to have black coat which was common for the dealer service men when they work for periodically maintenance required by the regulation. I have heard it was an additional service, they sprayed black all over the chassis without asking customers!! They don’t do it without customers request nowadays . I was asked by the service man , he said it is good for the car , no more black , it is clear coat. I said OK let’s do it . Kats

Thanks Gavin ,you said just I wanted to say . I really feel big companies are sometimes stressful for both , customers and employees . Yes very slow , even to answer just one question ... I really love both , a lot of trophies were brought by L-series engines from overseas (of cource in Japan too ) , and by S20 engines in Japan. I am so proud of myself being a S30 nut. Kats

Hi Locke , I checked some parts catalog, what I found is E88 started from September 1971. This was when S30 series had got a new center console, new hub caps , etc . I haven’t seen cars around mid 1971 in person, so I can’t say the catalog is correct until I see some examples. As a side note , E31 and E88 were meant to be “ low octan / regular gasoline “ . E30 was meant to be “ high octane/ premium gasoline “ , and this was never used for Datsun 240Z and Fairlady 240Z series . Kats

When the car was under restoration, a few things were not correct like a water pump ( for GTR ) , an engine block ( must be silver ) and an oil filter was for non- cooler type . I had changed them as you know , and the parts which shown I attached pictures are going to be on my spare S20 . And some of you may remember Mr. Takei , a chief engineer of developing Europe S30 team . He drove through Europe with his freshly rolled out Euro 240Z after finished his work , that was in April to September 1971 . After he returned, he reported to Dr . Nakagawa like this , “ Japanese automotive technology is far behind from which Europe has , I think 15 years behind “ Then Dr. Nakagawa said to him “ you go to Europe again and learn from them “ The picture was taken Luxembourg. courtesy Nostalgic Hero extra edition No. 564 Kats

Thanks Alan for the pictures of super rare heads , it is a little bit scary for me to seeing "knife edged " triming as I think there are not much meat left around it. Looks like my Z432 has a hand finished port for each , pictures from March 2007 at the shop . Kats
