  1. we recieved the 1973 ( AC ) do u mean a different shape of comp. was thier ?
    That appears to be a 'mist jet' type compressor. Nissan didn't utilize that type until 1979. A 1973 would have had a 'swash plate' type compressor which would be visually distingushable by the side cover which the one in your video does not have.
  2. "adieu" I thought I was spelling it wrong, but Google told me it was right...

    Well, yes and no. What you're trying to say is "Without further ado." 'Ado' means 'fuss or concern' while 'adieu' is French for 'farewell'. Looks like a nice 73. I owned a 70 and 72 in that color 'back in the day'.

  3. Not sure that there is a remedy for that. On another note, the option to ignore an individual member's post has probably been used with much higher frequency since sometime in December 2011 until now than any other time period in the past......

  4. I believe that would be the 'Performance Chart' on AC-57. The reason I say that is beacuse I have that page printed out and on the wall above my workbench. It along with the chart for the 810 I used to own weren't in the database I use. Anyway, pressures are only a part of the story, however, and should only be used as a general guideline. That chart also takes humidity and ambient temperature into consideration; factors which are as important if not more so than suction/discharge pressures. I use a charging machine which has a thermometer and a hygrometer on it and I charge by the recommmended system refrigerant weight rather than pressure. When I do put gauges on the system after charging it with the machine, the pressures are within the figures shown on that chart or the chart for the particular vehicle's sytem I'm working on. Using the machine it's 'one and done' while charging with cans or even refrigerant cylinders and gauges can be somewhat trial and error or hit and miss if you don't have a way to factor in temperature and humidity.

  5. The Shrader valve holds pressure (if it's any good). The cap just prevents dirt from gumming up the valve. I've removed a cap and heard a little "pssst", indicating a valve leak. The cap, if snug, would hold a little pressure but not much.
    I've actually had caps with good o rings hold the pressure that would have otherwise escaped through a leaky valve. ZCurves, how did you arrive at the 10 to 1 ratio? Generally, low side should be about 40°+/- 5, and 10 times that for the high side would be way too high.
  6. I have two IAPCO cap and rotor sets for 79 and up 810/280ZX and a used K and N 33-2010 air filter that would need to be cleaned and oiled. It fits 75-78 stock 280Zs, 77-80 810s as well as many other Nissans. Yours for postage.

  7. I got no beef here. I just thought the whole thing was a little weird... Out of the blue, mousemedic resurrects a year and a half old thread and posts incorrect information about 260's when the original thread wasn't even about 260's in the first place. ???
    That pales in comparison to his opening up a 9 year old thread to imform three of our Australian members of something they werent actually discussing. The most recent visit from any of those three guys was in September 2010.........:rolleyes:


  8. I was and still am more into jazz/R&B then I was into Mitsubishi commercials but do I recall the singer. Randy Crawford has a wonderful voice. She was somewhat popular in the aforementioned genre both here in the U.S. and in Europe beginning in the mid 70s. The song 'Street Life' which she sang with the jazz group 'The Crusaders' around 1979 or 1980 IIRC would probably be her most succesful release. She toured with them in Europe as well as being the 'Most Outstanding Performer' at the 1980 Tokyo Music Festival which is quite an achivement within her genre. That's likely how she caught the attention of whomever was responsible for the Mitsubishi commercial.

  9. Not sure how you'd go about boring out a cylinder head either...
    Or what good

    1) shaving the head would do if you're looking for piston to head clearance or,

    2) shaving the pistons would do, or,

    3) shaving both would do.

    Can't wrap my head around either of the last two.....

    All you are doing here with this combo is basically making a L26 motor.
    That would really only be true if you were also using the L26 rods and pistons along with the L28 crank (essentially the same as a L26 crank).
  10. That explains why I only have one. Good to know. I wonder why the injector side.
    All the EFI wiring is also on that side, the only thing on the other side is the spark plugs.

    Bob, your vents are on the way, should be there no later that Wednesday.

  11. On the back of that knob/switch there should be two wires, one that feeds power to the switch and another that sends power for it to the compressor. There's also a capillary tube that goes from the back of that switch to the evaporator core to sense it's temperature. Check to see of you have power to the wire that feeds the switch when the key is in the on position and your HVAC controls are in the position show in your attachment. If so, try jumping the two wires together and see of the comperssor comes on. That would tell you whether or not the switch is bad.
