Great pictures, Alan.  I'm wondering if it's cost effective to press out a few parts to make a few of these headers.   The end result may look too modern, yet still potentially faithful to the original design.

I would like to say thank you Alan too , those are museum pieces, if not you , I don’t know who will be able to show those . We are lucky to be here .

Yes , those parts are usually hard to see . 
 

Thanks !

I take great delight in the pictures too!  Great pile of snakes!

I think that would be appropriate if the context suited, but definitely a niche interest. And - as is often the case with Works parts - something of a moving target in terms of evolution. Which version to replicate?

There's also a philosophical conflict between original parts and replica/re-popped parts when the originals were never sold to the general public in the first place. Can be something of a minefield. I'm still not sure what I think about all that...  

 I don't mind replicas as long as they're not misrepresented as OEM parts.

Today , I would like to present a little observation for the knobs .

 I am thinking to install a hand throttle lever which was pulled from a 1970 Z432 to my #2146. I found the lever is flattened around a symbol that would indicate a continuous, long term use by the owners . Or is that a natural thing from the beginning ? 

Z432 , a S20 engine , most people preferred to start it without pulling a choke lever because of Mikuni carburetors .  Then it needs longer time to warm up than L-series engine , you will want to use a hand -throttle lever to ease your foot . 
 

So , my guess is a hand - throttle lever on a Z432 is more likely to be premature faster than a choke lever on a Z432 . 

On the other hand, L-Series SU carburetors need to be pulled a choke when it is started , and also used for warming up . Don’t need to use a hand - throttle for warming up . A choke lever for SU carburetors is always touched by hands ,might be premature much faster than a hand- throttle on the same  car . 
 
The last picture shows a tape that shields a tiny screw in a hole when it is new.

I don't see much wear on the symbols that would indicate heavy usage. I think they were made that way.

Yea, I agree.  I would think that the symbols would be worn, not the thickness of the knobs.

Thank you Mark Maras ,

 Your comment gradually made me think the lever would be snapped off or the symbols would be erased before it is flattened .  Just a matter of molding? For 1972-73 levers , I saw similar variations on a surface around a symbols .

Hi, not a S30 topic . Today  I was in a Nara convention center for new Z show time . It’s just about 15 minutes drive from my home . I really like this new Z , this is the first time that I would want a newer Z .

 I got into a cockpit, very nice ! And I didn’t forget to take a shot of a chassis number tag on the kicking plate  .

It is a RZ34-100014 , very early!! This will mean 14th of RHD RZ34 , I think 😍

A Nissan employee said this car is for testing, displaying, so never will make it on the road , sadly. 
 

Tamura san kindly visited my home and my garage , he said he really likes blue , so this time new Z blue is his strong recommendation. Also Tamura san started to talk about he dedicated his passion and time and money everything to L-series engine modification in younger days , he used to be wild on the street.

Hi , now Japan is in a rainy season . But today we had sunshine , so I decided to clean up an engine at a car wash . 

My friends kindly helped me out for this mission, I am very happy it’s results. Not perfect because I didn’t take off a front cover , and a fly wheel . There are two plugs each side ( front and rear ) , I wanted to, but I had limited time to operate today . General cleaning was the first thing to do .

This engine is on HLS30-02146 , L24- 005318 was probably sitting in a garage for last 30 years , I see very bad contaminations there . Rusty , gelled water in the block . We did our best , it was so fun !
