Datsun-240z Vs Fairlady-z432

[xs10shl]

I think I recall reading somewhere that one of the early Nissan design/studio teams was numbered 903RTZ. 

 

...I'll see myself out. 😀

Alan, in my CSP311 development uncovering, Nissan used A###X for their project codes (though the CSP didn't get one), e.g. A250X was an engine development of a SP311 engine and A550X was the still-born Nissan 2000GT. Was this carried on into the early, what would become the S30, which we see from the document as 270KK and changed (what I am asking is did it have an A###X first), or if I remember the CSP and S30 (for example) was designed under a different design studio's within Nissan? Thus, did each design studio/team have it's own code?

That's a good question, Ian.

I'm familiar with some of the project codes for the early to mid 60s period (such as the B680X) but I don't know much about the later ones and I wonder if there was some kind of re-arrangement or restructuring after the Nissan and Prince merger? I would imagine some kind of change being necessary, so I wonder if new project code systems were included in anything of that nature?

Something to look into for sure.

Here's my solution for replacing a PS30 Stock CDI with a Pertronix HP box, using the stock harness hookups.  It fit neatly on the existing bracket, with the aid of a pair of "hold-down" fender washers.

To get the Tach to work, I used an MSD Tach Adapter, as I could not get the Tach to respond to any alternate configurations using just the Pertronix setup alone.  The Tach loses accuracy as the RPMs increase, with a 700 RPM difference at red line (reading 6800 at 7500 RPM actual) but for now, that deficiency will have to suffice. 

The other change I made is to remove the in-line coil resistor from the circuit, which is a simple matter of removing the electrical tape, removing the 8" wire connecting the resistor and the coil, and storing it for later use if needed.  I'll probably just mock-up two dummy wires and re-tape it to the main harness to give a stock appearance.  Of note, I think one can hookup the stock distributor trigger wires as well, but a prior owner had removed a good chunk of the wiring already, so I just used modern purple/green wires, bypassing the harness hookups.

edit: in thinking a little about this tonight, I may consider adding a jumper to "Ign Start" to the +12v switched input of the Pertronix, and monitor the results.  The car starts fine without this feature, but it's a little awkward, as some power is disabled during cranking (by the design of the ignition switch), which causes the Tach to jump twice.

Thanks xs10shl, this is a great work and I am sure this log will be a nice instruction guide for everyone who need to install the system into a Z432 , probably for GTRs ( PGC10/KPGC10/KPGC110) too .

Ignition management is a key of those cars , no more new parts from Nissan today , and there is no singles part which is interchangeable with a stock L-series engine system. Even if someone has a complete , perfect S20 but without working ignition system ,it will be sad for the car and for the owner . 
 

Or like this , I am a bit fool for S20 even if it doesn’t sit on a car . Just looking at the machine, I can spend whole day of my life . 
Except Alan ,I don’t think we can explain about this engine. This is probably a pinnacle of existing, working of all the S20. I will report when this engine starts fire up in a car .

I can do the same thing when looking at the Rb26 in my Nissan Stagea (260rs). I have been fascinated with the RB26 for 20+ years and I just like looking at the engine in the bay at times.

What ??? Why does YouTube  prohibit seeing American rock video in your American home ? 
By the way , has Nissan USA ever used their song for TV commercial? I just imagine and it seems to me their name “ ZZ Top“ is suitable for selling Z cars .

Hi , today I would like to show you this , a NOS trim panel for my car . Thanks @SteveE, I appreciate your great help . This piece is now very hard to see in this condition, not only for the early car style ( non-access panel type ) , also this is a blue panel ! 
I can confirm the real color when blue cars left from the factory . Next time I do some work for my new blue 240Z , I will show you the difference of color between two of them , old and new .

I need to work for the car as it deserves this beautiful piece. It will be a long way . Or I will put this on my -2156 until -2146 becomes beautiful.
