Lunar240z Posted September 22, 2005 Share Posted September 22, 2005 I have a '71 240z that came with the ARA a/c it's not hooked up, the compressor was gone when i bought it. i know i want a/c back eventually, so my question is, am i better off getting a completely new a/c kit from MSA, and removing all the ARA stuff, or should i try to piece all of the ARA system back together? What would cost more? what set up is probably lighter? thanks. Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted September 22, 2005 Share Posted September 22, 2005 It will likely be cost comparable. If the system has been open for a long time you're better off looking to replace all. That's just one man's opinion. Quote Link to comment Share on other sites More sharing options...
zgeezer Posted September 23, 2005 Share Posted September 23, 2005 I have the same car, same ARA dealer installed A/C, and same question. Right now, I leaning to reuse the ARA evaporater, a 280 condensor and dryer, a Civic A/C fan, and the GM compressor that came with my motor. But, I'm also considering the smallest Vintage Air. The advantage, as I see it, to Vintage Air is that every thing is well matched and it will, in fact, work and work well. A bit pricey and I'm not too hot at fabricating mounts. /// Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted September 23, 2005 Author Share Posted September 23, 2005 How much smaller is the vintage air setup? The ARA system is big, and i'm not too sure of it's effectiveness... Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted September 23, 2005 Share Posted September 23, 2005 Basically you would gut the heat and a/c unit of the Z. The Vintage Air unit would mount in it's place. The smallest is on the scale of 9"x7"x19". The blower motor forces the air thru the combo coil assembly (blower fan are designed to push not pull). The ARA pulls through the evaporator and pushes through the heater core. The only two downsides of the combo unit is recirculated air only and the a/c and heater cores are integrated. If one goes you replace the core as a unit. The upside is compactness, effectiveness, and longivity if you maintain your coolant system.

It looks like hotrodair.com offer a fresh air option now, so recirc only may not be an issue. Quote Link to comment Share on other sites More sharing options...
