kats Posted September 12, 2016 Author Share #625 Posted September 12, 2016 (edited) Chris, Like you said I am doing a bit strange! But I always can not stop myself from buying something if there is a old part which is wrapped with a Nissan paper. I too want to see how crankshaft is doing well in a S20 engine even only 4 counter weights. Yours is balanced with assorted parts, that is great ! Chris, is your crankshaft has an early less counterweights? Please let us know when you fire it up in someday !

kats Posted September 12, 2016 Author Share #626 Posted September 12, 2016 (edited) 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 .

kats Posted September 12, 2016 Author Share #627 Posted September 12, 2016 (edited) 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! Kats Edited September 12, 2016 by kats Link to comment Share on other sites More sharing options...
kats Posted September 12, 2016 Author Share #628 Posted September 12, 2016 (edited) 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. Kats Edited September 12, 2016 by kats Link to comment Share on other sites More sharing options...
26th-Z Posted September 12, 2016 Share #629 Posted September 12, 2016 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. 1 Link to comment Share on other sites More sharing options...
Fred Sigarto Posted September 12, 2016 Share #630 Posted September 12, 2016 Kats, I'll check my early 10/69 Fairlady Z-L when I return home in a few days. 1 Link to comment Share on other sites More sharing options...

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 !

kats Posted September 13, 2016 Author Share #633 Posted September 13, 2016 Thanks Blue, I think the 00002 is still sitting outside and just wrapped by a cheap cover. Must see before gone . Kats Link to comment Share on other sites More sharing options...

240260280z Posted September 13, 2016 Share #635 Posted September 13, 2016 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 1 Link to comment Share on other sites More sharing options...
kats Posted September 13, 2016 Author Share #636 Posted September 13, 2016 (edited) 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.
