  1. Hi, right now i am in the process of fixing all small issues with my Fairlady. Since you guys already helped me I want to try my luck a second time. I had a look at the vacuum lines and to me they seem to be set up in a weird way. The car is a '78 280Z with a 280ZX engine (L28E F54 block with P79 head) converted to Ztherapy SU carbs and original AC. The engine runs fine apart from a slight fluctuation in idle speed (every 3-5 second it goes up from 800rpm to maybe 840rpm and then back down again). I checked all the FSMs to use the correct terms in my drawing and I added three pictures of the current situation. Especially the wrong plumming of the servo diaphragm and control valve +the missing connection to the carbon canisters vacuum signal line seems odd to me. If i understand the original piping correctly then I would expect that the servo diaphragm is doing nothing in this setup (have to check if it moves during let go of the throttle) and that the carbon canister is only doing its job in 'idle mode' due to the bypass mentioned in the haynes manual (because the valve for the purge line is never opened by the vacuum signal line). Another point is the missing of the EFI specific FCID. The AC is not working at the moment so i don't know if the car runs fine without raising the idle rpm. I wonder if it would make sense to pipe the FCID magnet valve to the control valve to use it as a 'carb FCID'? My overall question to the experts is 'Do i need to be concered about this vacuum setup (do i need the servo diaphragm/carbon canister to do their work) or is this maybe a clever solution?' Thanks in advance for your time and help. Picture 1: Picture 2. Picture 3.
  2. Last Tuesday I took RedBird to Sam, who is installing her new air conditioner. Yay!!! I went by today and took a few photos of the progress to share with you. Boy the compressor sure is shiny. I'm so happy that this is finally happening. I'll keep Y'all posted on her progress. Jai
  3. Is anyone running a harmonic damper and A/C? I'm trying to figure out what my drive options are. I'm using the ATI Damper kit from Datsun Spirit. https://datsunspirit.com/shop/ati-harmonic-damper-kit/ I suspect my A/C days may be over.
  4. Air Conditioning kits available for your Datsun 240Z, 260Z and 280Z. Complete kit with all new parts using R134A refrigerant. 240Z and 260Z 70-74: https://zcardepot.com/engine/air-conditioning-kit-complete-a-c-240z-260z-70-74.html?search=air 280Z 75-78: https://zcardepot.com/engine/air-conditioning-a-c-r134a-kit-280z-75-78.html?search=air
  5. I have a '75 280Z that has the ARA dealer installed AC. The car was dis-assembled when I got it and I am trying to put it back together. I have all the major components but am missing the AC control switch and the thermal switch. Any power switch should work but the therrmal switch for cycling the compressor may be another matter. Does anyone know where I can find this switch and how does it install in the evaporator box? Is this an item that can be found at any AC shop or is it specifically calibrated to the 280Z evaporator? Any help would be appreciated! Brad
