xchevyimpala69x Posted October 8, 2007 Share Posted October 8, 2007 Well I'm new here. I recently bought a 73 240z with a 5 spd for 900 bucks. I went to the junkyard a while back and i found a 240z with a MSA (is that right?) a/c system, so i yanked it out. Im in the process of installing it, and i was wondering if any of you have pics of how it should be set up in the engine compartment (L24). Does the alternator have to be relocated to the drivers side with a special bracket, etc.. i just wanna make sure i have everything i need, and comparing what i have so im sure i didnt miss anything. thanks again, and yes ill continue searching the forums for some random pick that may answer my question (so far no luck) thanks again.

rigez Posted October 8, 2007 Share Posted October 8, 2007 I went with the msa a/c unit in my 74 Fairlady. I can honestly say its not worth the trouble of installing it. Go with a aftermarket from Vintage Air or Hotrod Air. I will be using the Hotrod Air because they have an option to use the OEM heating/ac panel. Even with the fan upgrade it doesn't get cold enough.

Zmanco Posted October 8, 2007 Share Posted October 8, 2007 The stock compressor from a later (80 - 83 zx) and its bracket will install nicely on the driver side so you don't have to mess with the alternator. You should be able to find one in a JY in the Bay area. That's what I did with my '73 and the original dealer-installed system. On the freeway it's cold enough to drive with the windows up and remain comfortable. While you're at it, put a 90's Honda Civic blower motor in to increase the airflow. It moves more air and makes less noise. Quote Link to comment Share on other sites More sharing options...
nbesheer Posted October 8, 2007 Share Posted October 8, 2007 Also might not want to get a system that uses R12 because I heard that using R134a will not work properly with the R12 compressor. This could be false information though. Quote Link to comment Share on other sites More sharing options...

Yeah i should have done a more modern swap, but man it was all there, i didn't know the msa system was that bad , really though does it suck that bad? haha im already half way through the install thanks Quote Link to comment Share on other sites More sharing options...
