Hi Alan , you have an early one, that is wonderful and very clean , your yellow is no need to do something, I like it . Yes there are holes for the bracket , that is why I want to try . And I want people to know the bottle is useful for everyone. Not original for L series engined car , but this modification is easy to resume normal so purists can take this “ just a while “ . Kats

Gavin. I made you confused, sorry. I am trying to install the bottle into my Blue 240Z . The first picture is the one which I recently bought , and This is going to be on the 240Z . The bottle is STD equipment for the Z432 and Z432-R . And not applicable for any other S30 models. Nor available as an optional item. I too think why only Z432 ? Why not on 240Z ? This bottle was shared with Cedric/ Gloria at that time , they have different brackets though . Kats

Thank you 7tooZ and 240znz , I wish Mr .Tamura could tell more about our cars. Kats 7tooZ , I will send some pictures of the fog.

My Z432 , when the restoration was in progress , the car did not have a metal neck. Lost at some point for sure . And an original bottle was very yellowish. So a new 3rd type bottle and an original bracket were joined as one. Later I found a metal filler neck and , the metal cap is still available at local Nissan dealer today. Kats

Thanks Patcon & Gavin , I saw the thread , they are really useful information , amazing work ! The bottle is very thick in its wall , I assume it gives a lot margin to avoid crack/ deterioration . Here are the depth of differences of the bottle by date.

Hi , here in Japan everyday so hot , I am worried about my cars can be melted down . Today I am going to show this , a reservoir tank for Z432 . I think it is also good for other models , especially in height temp operating during in Summer . I will report when I install it . Can I make it more white like new ? Kats

Hi and thank you everyone here, this is an old thread. I suddenly wanted to put this picture. What do you see in this picture ? I see a beautiful female face . She has got beautiful eyes and nose and lips . Many people were involved in developing of this car , but Mr Tamura did a great job . Who was there always in his mind when doing this beautiful work . Kats

Hi Captain !! You are the best engineer for helping others , I wish I can do it for my cars like that . Kats

So, if you have the electical fuel pump near the differential gear on L series engined car like Nissan manual said about Z432 fuel system, it will help for preventing percolation , but I think it will not make a big difference. Like everybody here think SU carbs on the exhaust is the problem. I think Nissan manual should ammend saying like this , " Z432 has carburators opposite side of the exhaust headers. This prevents vapor locking / percolation " , not come from fuel pump location . However our cars are no ploblem under 90 F with a stock fuel configuration as long as cars are cruising . Kats

Thank you everyone, I am learning, should not be confused about percolation and vapor lock . I am a student here ! Kats

The Fairlady Z manual says , Z432 has a fuel pump ( electrical ) which is located under the floor near the diff . This prevents vapor locking . The reason why Z432 does not have a fuel return system is , no need to concern vapor locking . I did not know that , is this true ? Kats

Hi Don , thank you for the joining here , Yes I still use the mechanical fuel pump and the cooling fan , I do not want to change those things because I love Stock . I have had a trouble once or twice about fuel during my ownership since 2000 , that was overflowing from the SU carb fuel chambers . I opened the chambers and checked the fuel floats, they seemed twisted sideways and sticking to the wall , then fuel valves were stuck open. If I drive my Z in a traffic jam under such a hot day , I will have the same trouble again . Oh , when I brought my 240Z for Las Vegas ZCON 2000, I had a vapor locking . I parked my car under the strong sunshine , after returning from the drugstore , the engine hesitated to fire up . I tried to start several times , then finally I made it . Nowadays Japan’s summer is extremely hot , tomorrow will be 37 degrees Celsius (98.6 Fahrenheit) , when I was a kid , max was like 30 C ( 86 F ) . We can see this in the first service manuals ( Nov 1969 ) , a section Engine shows SU fuel mixture diagram. The diagram has a scale only up to 30 C or so . This is my biggest question, people in hot area like you Don , did they have a vapor lock trouble back in 1970s ? Was it not hot that high back in those days ? Kats

Update of my blue 240Z , I replaced an water pump, it went bad after a few months I reported here last time when I installed the metal fan . Anyway this previous pump was old enough to be going wrong. Also a thermostat, a radiator cap , and installed a fan shroud . Kats

Hi , this is not related “ build date “ but I found this wooden grip reversible driver is bare wood , I mean not covered by clear lacquer. This is found in a May 1972 tool bag for Nissan Blue Bird ( 510 ) . Dec 1969 Z432 has a lacquercoat wooden grip , so there would be a difference between them , early has lacquercoat , later does not . Kats

Hi everyone, today I show this , early bumpers. The earliest bumpers are unique, for example, the front bumper has only one stud bolt per each side. And the associated brackets are very thin . These are the same for all the early S30 series cars. But I do not know when it bacame to two bolts per side. Once I was told by a 1970 Z432 -R owner , he told me that he thought his car has very thin bumper brackets because of his car is Z432-R . And the rear bumper, it does not have a recess near the side mount bracket for each side. This is true for at least up to 1973 model , including Fairlady 240ZG which has gun grey painted bumper. Some of you noticed already, my Z432 has later ones. They are genuine stock bumpers from Nissan , but they all were purchased around 2005-2007 . We all were happy that Nissan still providing these old parts , but we were little bit unhappy about its quality about chrome. The finsh of surface was not so good . You can tell from the pictures , about front and rear bumper’s imperfection. The original old bumpers has much better chrome I think . Today I show my re-chromed early bumpers , one bolt version on a front and non recess version on a back . Safari Motors ( remember ? They are taking care of Nissan’s historic racing cars ) did a wonderful job for it , but expensive!! Kats

Hi Gavin, the brochure is unique I think, I have never seen it on outside of Japan , I do not know why , I purchased this at Yahoo Japan. I do not know what countries received this brochure, anyway this looks general purpose for use. I really love the blue RHD car ! In Africa, whao. I think someone said there is a super low VIN car like a digit in Africa, have you ever heard of it ? Kats

Hi Blue , I was surprised you are doing it , how can you do it ? It helps a lot for understanding its details , original photo is not good to figure out what each pieces are . Here are the color pictures , and the one showing the engine bay looks the same car what we are talking about . Could you see the float has two pipes at one connector? Kats

Thank you everyone! I love both TOPY STEEL and KOBE SEIKO magnesium. I visited my friend on Monday, I was surprised that my friend bought the set of Z432 wheel ! The seller has owned his Z432 since he bought it new from Nissan , he took of them when he scratched edge one of them . That was 40 years or more ago ,then they were on his shelves until showing up on the auction. He is a doctor, doctor loves Z432 ... I check them and they are truly original and fantastic appearance. Kats

About the wheels on Yahoo Japan, I asked the seller weight of each wheel , but they never replied, I new it . I think the seller did not want to tell they are aluminum replica. The seller would want to have a lot of attention to raise bidding price. Kats

Hi Gavin and Patcon , I enjoyed the links so much , thanks Gavin . I bought the NZ magazine from eBay years ago , that was for the first time for me knowing there were options of the wheel and the stripe , the rear spoiler and even the front fender mirrors!! Still the car is arrive , wonderful. And the “ D “ center cap , I want it . There are only two cars I know which have the caps for their Z432. I know many Z432 owners still use the wheel ,but yes , basically people who saw the car said it is dangerous because it exceeds its life , lost worthiness. So I think there were some reproductions made of aluminum, Toyota 2000 GT too, not only owners also other models owner bought reproductions. But they are heavy! According to a Nissan Life ( Nissan issued magazine for customers) , interviews to Mr . Nanba and Mr. Wakabayashi after the winning of 1971 Safari rally, they said the magnesium wheel is way strong than the steel wheel , steel wheel is bent on by certain impact , while magnesium wheel is broken apart at very high stress. Manuals recommended wash your magnesium wheel very well after driving in salty waters. If owners take care of them well , the magnesium wheels are always good for use , I think . Some professionals can restore the wheel but I do not know the case which you provided in the pictures . Kats

Hi , I saw this auction in Yahoo Japan , but it was too late . Just after an hour of starting , it was sold out with buy it now . https://page.auctions.yahoo.co.jp/jp/auction/t572315354 5 wheels with caps and even they still remaining original air valves . 1 000 000 JPY , last time similar a set of 5 wheels was sold for 1 500 000 JPY.

Hi , Here is another kind Z friend , Mike B gave me this wheel nut wrench which is the best combination for 01/ 1970 Z432. It has only a Nissan hamburger , and simply showing an alphabet “ I “ . My 03/1970 240 Z has the same wrench and it has “ J “ on it. And a teeth for the removing hub cap is pointing different, early one is facing same direction as the nut socket . I think later one has like this , “ NISSAN ( NISSAN hamburger ) MOTOR “ My 06/1972 240ZG has “27 “ on it , what does this numbers mean ? And Mike rent me tools contents papers , early one has colored Nissan hamburger !! I have never seen it before . I will make replica of them for Datsun 240 Z and Fairlady Z , and Z432 . They are different each other due to tools line up . Thanks Mike B !! Kats

Yesterday I replaced a heater hose of my Z432 , it was deteriorated. The Inlet hose for heater is much more stressful than outlet hose, especially S20 engine creates high RPM , and circulation of water is very good , it means water runs very fast. And During the operation I broke a heater control mechanism. I had to disassemble the heater control facia , I added my work road by myself! I was so glad that the control mechanism trouble was only a steel wire , it was going wrong as it pushed so hard that the wire’s 90 degrees corner could not stop hold the lever. I fixed the wire , and pulled all the wires from their plastic tubes to lubricate . And I put a drop of oil on the every pivot and contact of the mechanism. Now levers move nicely, no effort for selecting positions. I was lucky I did this maintenance before breaking the mechanism and plastic control facia . Kats

Hi Lumens, I did not realize that, I was wondering what the huge threaded hole is for . I checked service manuals , ( 1st NOV 1969 for export , NOV 1969 and OCT 1971 for Fairlady Zs) there is a Nissalco ? stand , the difference is an adapter for each type of engine. And you will be surprised, Fairlady Z manual is omitting description of disassembly and assembly for L -6 engine , it says “ because it is the same as L16 engine, omitting description “ Kats
