Thank you for the photos, @kats. Matsuosan talked about the AC in the 240Z when he was at ZCON in 2018. I can't remember if it was during his presentation or when I was helping him with making the slides for it. He said he received push-back from the engineers because he wanted the evaporator to fit behind the center stack.

I don't think I ever saw the eventual solution. If you have a chance, could you post more photos of the AC components?

Thanks Steve , you helped Matsuo san for the presentation, must be wonderful time for you ! 

Yes I would love to post pictures here when I am home , they are so interesting to see I guarantee it.

I have heard it was not easy task to have the system in dashboard because it was so small room for the system. 

Matsuo san or Uemura san ? Told us Toyota 2000 GT couldn’t have it in a dashboard, but on the rear deck behind the two seat backs, a big box dominated the space . It was not cool at all . 

260Z and 280Z have a factory installed air-con system, I am feeling those system were updated version of Fairlady Z series air-con system from Oct 1969 to Aug 1973 . But basically the same, both systems use vacuum power to move the inlet doors / airflow direction flaps .

@kats I have a 260Z evaporator on a shelf in my garage. I'll take some photos for your for comparison.

Not wishing to steal Kats' thunder here, but I have previously posted scanned pages from the aircon section of the 1969 'Z1' Nissan Service Shuho booklet and perhaps this is a good time to post them again.

It seems to me that many early Z enthusiasts do not know that factory aircon was part of the original 270KK/'Maru Z'/S30-series design, even though the tell-tales are there for us to see on every early car - Export or Domestic. I'm surprised more people do not notice them...

A true 'Fully Loaded' early Z with all the bells and whistles would have been quite something in late 1969. World Class.

I don't think it's stealing any thunder. I appreciate you re-posting the pages from the manual. It's always good to compare the photos to the manual, too, since it can be a challenge to track the errata in manuals.

s20 with Aircon.  Why not? there's plenty of room for a compressor, actually.  As to the F.I.C.D - probably set the fast-idle to 3000 RPM, LOL!.

Thanks for re-posting these, Alan.  There were a few pages I hadn't seen.

I think about the "option list" decisions a fair amount, especially given the decision to not even offer the US market a 5-speed - essentially the same gearbox they had already been selling in the US for 3 years. The 1600/2000 roadster data should have been enough to demonstrate a hearty appetite for upgrades. It was possible for Nissan to build a 240Z-L (for lack of a better term) with all the features in 1969, and of course sell that car at a markup - and I'd venture to say they would have sold every single one.  it's just the road not taken.  I can understand that perhaps in 1970, it would have been tricky, given the ramp-up in volumes. but by 1971, it should have been straightforward.

So Kats, if it's between a PLS30 and a loaded HLS30, you cant go wrong.  A fully optioned 240Z-L, based on factory components, would be a very worthwhile project.  Someone was selling the near-correct compressor on Y!.jp a few weeks ago for big $$$.

Hi Kats. Do you have a copy of this 1970 Fairlady Z air conditioning manual? It notes the air conditioning system can't be used on the PS30.

I've been thinking about fitting aircon to all my S30z's. With the change in summer over here in Australia in the last 20 years. Summers in a Z on a hot 35-40 degree day it's just unbearable to drive.

I want to have less excuses to not take my Z out and enjoy it. So for me fitting aircon is the way to go.

Funny enough my 72 (red 240z) HS30 10552 had dealer option aircon at 1 point. But was since removed by a previous owner. I suspect when the dash was restored.

My 71 240z HS30 01415 automatic still has the dealer aircon set up. Which I intend to upgrade the required components to have aircon it all working again.

I'm very interested in the Fairlady Z-L aircon components and how difficult they are to source now?

Not great photos, but AU market dealer fitted system on my 71.

Thanks everyone, I ran out “like button” ! 
I need a jet fighter aircraft, I want to reach my room and show what I have for you, now !

Kats

Oh , S30-00002 has air-con too ! You can see the beautiful check valve junction, one of the coolest looking piping and connectors among cars around 1970 .

Kat,

Nice S30-00002

Cheers, Kirk

Does anyone know what happened to that car? I recall seeing those photos of it on this site at least 15 years ago. But no follow up on where it is now?
