Datsun-240z Vs Fairlady-z432

    Recommended Posts

    Here are some pictures of my parts which I will never use(^~^)

    Exhaust system for Z432, 

    E4200 is for an early type, E8710 is for a later type when new console / prop shaft started to apply(joint position is slightly different) .

    And an exhaust header, mine is painted by the seller unfortunately, this one was sitting on a shelf from early 1970 ( the seller even did not remember this is a NOS or used ) , it must have a part number stamped on a tube, I wished I could see it.

    The 4th picture is for a reference from yahoo auctuon, the NOS exhaust pipes has the part number as you can see .

    More exhaust, this is a Nissan race option header for L24 ,

    I think this can be used for LHD , I am tempted to install this to my HLS 240Z in some time. When I do that, E4200 (for 1970 blue 240Z)/ E8710 (for 1971 orange 240Z or 1972 ZG)  exhaust system will come together.

    My friend (240ZG owner) is doing something nice, this race header with SU carbs. He said it is fun to drive, no need to have Solex!

    An error occurred in an assembly line,

    You see the double spotted welding around the shock tower, this is  

    unusual, I think the worker missed welding. Is this because my car is an early production?

    Passenger (left ) side is normal.

    Hi Kats

    Yes, I have the early crankshaft with six counter weights.  My engine numbers are L24-2338 (26th-Z) and L24-2162 (27th-Z).  Service bulletin TS70-28 (August 1970) indicates that beginning with engine number L24-3607, eight counterweights were used.  My engines also have three different lengths of cylinder head bolts as described in service bulletin TS70-15 (April, 1970) which indicates that from engine number L24-04257, two lengths of cylinder head bolts were used.  I was lucky enough to find the three different lengths when I rebuilt the engine.

    One spot weld appears to be deeper than the other.  Perhaps the spot weld machine was not working properly or it did not stay in contact long enough.

    Thank you Chris,

    This photo makes me think it was a  bit difficult to patch a shock basement dish with a tower, were they welded together prior to meet a wheel arch ?

    If I were there and watching it,  I would ask the worker "please do not use a failure piece, use new one"...

     Here is a good example, her sister PS30-00087 has a good spot welding on the both towers.

    And about early head bolts, you are so lucky obtained it, just great.

    Fred, let us see what you see !

    FYI  I tried to colour correct the pamphlet photo below and the yellow paint of the strut bolts/nuts popped out :).... just like yours!

    I first thought they were bright cad/zinc plated

    Blue,

    I did it too much, it should be just on top of the stud bolt.

    I see Nov 1969 Tokyo motor show car has yellow painted on the bolts of shock towers, very cool.

    My 240ZG has sitll yellow paint little bit on the bolt.

    I admire this part greatly, with perhaps a touch of envy.  Keep finding rare parts such as these, and posting pictures for us.

    Hi, 

    I saw my L24 , there are some differences between E31 and E88. Have we talked about this already?

    How do you say this tiny banana shape of the cylinder head? Length of the banana  looks different, I think E31 is longer than E88.

    What do you think of it?

    Kats 

    PS. The last two pictures are  racing special head, you see the ribs and blank for fuel pump location. Thanks for Kubo-San , Speed shop KUBO .

    Hi Kats,

    you are exactly correct in your observation of E31 head differences.

    someone who was a noted Z engine builder tried to sell me an E31 

    head that had the E31 ground off of the head.  I brought this mold 

    (banana) difference to his attention and he admitted that it was actually

    an E88 head.  Unfortunately, he (who will remain unnamed) is still in

    business.

    Sorry to possibly confuse the issue, but I have E31 heads here that have both the short and long bananas. I don't mean a mix, all long or all short.

    The long banana E31 is from HLS30-164xx but the short banana E31 I cannot pinpoint as to build date or original VIN. 

    I wish this marker could be more conclusive. Perhaps it does apply to early heads, but not later ones. Just a guess.

    Any others with this experience?

    By identifying the guy as a "noted Z engine builder" you're placing suspicion on every noted Z engine builder out there.  Doesn't seem right to do that.  Better to just ID the guy and let him explain what he was doing.

    My Z432 had its  transmission rebuilt in 2013, here is a link of Mr.Kawashima 's web site. He has been rebuilding many transmissions for S30 and Skyline. 

    This time I ordered him rebuilding my another FS5C71A which was kept in a garage as a spare.

    Tomorrow the spare one will arrive at local Nissan near my house, I will report replacement job at Nissan.

    This is the work in 2013,http://www.vintagecraft-e-za.com/s30zのページ/旧車のレストアは楽し/71a3分割-空飛ぶz432/

    And this is the work just completed last week,http://www.vintagecraft-e-za.com/s30zのページ/旧車のレストアは楽し/71a3分割-空飛ぶℤ432その4-1/

    Arrived at Kyoto Nissan , waiting for installation.

    I found previous transmission has wrong order of assembling about a plate and spacer. A thin plate should be under the spacer, not on the spacer.

    This will be corrected when  the new one will be in position.

    By the way, is it repairable? A winner of an auction is now very unhappy when he saw rusty water came out all over the block , transmission. Winning bit was 31000 USD.

    On the other hand, a new in box S20 head only (no cams/ valves/springs/etc) was 25000 USD on Yahoo Japan auctuon .

    Kats, this one sold back in january and was "rebuilt" but they didn't give an engine builders name in the auction.

    If his is rebuildable then he's got about  30k usd to pay an engine builder if you compare it to this one.

    Do you know Uchida Motor Works in Tokyo?  Pictures on his website show quite a few s20 engines in his shop.

    http://victory50.com/index2.html

     

    He is quite the fabricator. Do you see the cable driven tach adaper he made for the s20?

    I'de be curious as to what he charges for a complete rebuild.

    Kats,

    I firmly believe that the illustrations of the rear mount and spacers in the Nissan parts manuals are wrong, and that your car - as currently assembled - is correct.

    I came across this when I was assembling my S20-spec FS5C71A rear mount, and it seemed to me that the Spacer shim (11335-E4700) acts as a load-spreader for the two 'Distance Pieces' (11336-E4200), protecting the cast aluminium transmission case from localised loading where the two Distance Pieces touch it. 

    On the L-gata version, the mount simply bolts direct to the transmission rear case and the load is spread across the full shape of the mount. This is most closely replicated If you bolt the Spacer shim between the Distance Pieces and the transmission rear case - as your car is now. If you bolt the Spacer shim between the Distance Pieces and the mount (steel to steel), then what does it do? It seems to me that it does nothing useful...

    I'm not keen on contradicting Nissan technical illustrations, but to me it seems that this detail was wrongly illustrated, or at least illustrated from an incorrect assembly.

    What does Kawashima san think about it?

    Hi hr369,I have been there a few times. Mr.Uchida is very passionate for Hakosuka , I wish he becomes more being interested in S30, but yes he is very busy on Hakosuka.  I think he does nice work and price is reasonable.

    Hi Alan,

    Thank you so much , I take your comment and I keep remain the parts as it is , not follow the manual.

    I think this is woderful ! we are leaning every day, we are finding correct thing even Nissan does not know.

    I was thinking same thing Alan, I really felt natural to seeing my mounting parts, and I really liked those special parts only for Z432.

    If I did the work without seeing the picture of the service manual, I definitly would assemble the distance piece

    between the spacer shim and the mount .  

    If the distance piece was really need to be touched to the aluminium case, also need to be a certain distance, I think enqineering designers would just make it longer about 2mm. 

    Then  you do not need to have the spacer shim like you said , Alan.

    Every Z432 I saw has this muonting style, I attached 3 pictures of Mr.Watanabe's , Z432 at Mega web Odaiba, and

    the 31000USD yahoo auction S20.

    This leads to me remember a story of cracking problem of the transmission rear case when Z432 was in a race track back in 1970-1971.  Some Nissan factory racers told us  ''it was very notorious the vibration of Z432-R's

    transmission, sometimes it cracked...''

    So, I think this could be the cause, the distance piece damaged the aluminium transmission case in a very high speed and much stressed situation.

    Can we say we found the reason of that?

    The last picture is my another spare FS5C71A which has totally cracked in two pieces
