As far as as know, is that The S1 was a sporty version modifyed by the portuguese dealer Entreposto Nissan.
There as rummors about an S2,but I have never seen one.
These are the changes:
Mechanical changes
* double valve springs
* free flow exhaust system
* head work (+compression)
they claimed more 6 HP at the time.
Other
* Tach meter
* oil pressure
* amp meter
* fog lights
* S1 badge
* Larger weels
*smaller sporty driving wheel
+large stripe on each side of the car
Some body modifications that I only found when restoring the car: the interior of the flares was bent over from 90 degres to 180, so you have more space for the enlarged wheels.
you can find pictures of the central console in
hereI this album
Pre-Rustoration you can find original pictures of an Datsun 1200 S1, when we bought it the car as completly original, never had a paint job.
this is our third 1200, so you notice that in this one you the engine revs a lot easier at high rpms.
You dont see so many S1's in Portugal, the car was reasonaly more expensive compared to the deluxe model.
Many try to copy some of the S1 look, the enlarged wheels, the central console, or the sports driving wheel. I have only seen about 4 that I notice they where original
I will try to investigate more about this model, rumors said that the mentor of this car was a guy called "Saraiva", so I dont know if the "S" is from "Super" , "Sports", "Sedan" or this guy last name.
Thats all I know of,
Daniel started a discussion when we boght the car, you can discuss it in the forum
