AC help for my 89 SR20 S13!

[jdm>usdm]

Been doing a good bit of research and have found a few things, but still have some questions.


First of all, when I bought this car, the previous owner handed me some spare AC lines and said only one is missing for the car to have AC. So I've been trying to install these lines and identify what will work and what I will need. The car already had a compressor bolted to the engine when purchased. Anyway, here's what I have.


First up, here is the low pressure line connected to the fire wall fitting. As you can see, it easily reaches. I read that the SOHC line wouldn't reach far enough, so I'm assuming this is from a DOHC chassis. Could I just bolt this up to the compressor despite the line having two bolt holes and the compressor requiring one? Also, I'm still unsure if this is a DOHC KA compressor or that of a SR. The wiring and plug seems to be completely missing too.. guess I'll have to figure that one out.







Secondly, here is the line which feeds the condenser.



Here is the line which I have that seems it should connect the compressor to the condenser.




As you can see, both fittings on the line are just a single bolt style, while the condenser requires an entirely different fitting. Is there some kind of adapter for this? Or do I need a completely different line?




SO, overall, I'm just trying to find the cheapest and simplest way to do this. Do I need different lines for both the low and high pressure that connect to the compressor? Or would a different compressor be a better solution? I'm unfamiliar with this AC stuff, so any insight would be appreciated. Thanks
