Hello Kats,

For me, the mid to late 1960's and very early 1970's was the peak of car design in Japan, with great looking models and performance (even those with less performance still looked great). The S30 family is no exception, but I hark more to the rarer/less produced models within the range. Ahh, the late model RS30Q....!

Silvia, it's going fine, though slowly. Your statement (I quoted above) can easily fit into it with finding spares for a production run only about 100 more than the Z432. I had been looking for a pair of seats for about 12 years, and finally I brought with a small fortune considering they were for restoration only.

I think so too Ian , Silvia is very rare to see , rarer than Z432 maybe !

Hi Ian , what a surprising thing this is ! I was going to miss it if you wouldn’t notify us . This is the earliest  version as it doesn’t have a small pipe which is sticking out from the rear top surface, for the blow-by tube from the valve cover . 
A buyer need to source a Darin plug and a tube at the rear bottom, and four pieces of brackets ( three for the long heater outlet hose across below the three Mikuni carbs, one for the fuel supplying tube from the strainer).

Carrying on from Kats post 11, regarding additons for emmisions cam cover and engine block breather pipes,  here is the back of 2 GT-R air boxes. Blue is NOS and earlier, without metal pipes for rubber hoses, whilst the red is later and has provision. I get the impression the design for emmision attachments to the airbox due to come later on were incoporated, as the engine block breather stamping on the box is there from the beginning (blue box), slight curve in the strengthening rib.

Enjoy

Very cool, thank you for posting.
