Thread: "Project A/C to beat the heat" "Pics Inside"

A/C Project: 5 speed 93 SE-R N/A
Want: Cold A/C - R134a system from a 94-98 SE-R.
To Know: What all I need to replace while doing this project.
Mission: To have it working by summer so I want sweat my ballz off.

INTRO: - Ok I have had my daily for three years this coming March and I haven't had A/C in the car since I purchased it. I have went two summers in GEORGIA heat, and I want make it a third. I'm jumping on this early to get a head start to see what air compressor I need to get and what other parts I need to have it in 100% working order. I know I need to covert to R134a, so let me know what you guys are doing.

NOTE: - For you guys that say, hey man don't worry about A/C. Get rid of the clutter and reduce the weight on your car. O yeah, and while your at it, get the power steering junk out of the way as well. Well, I'm not interested in sweating my nutz off in my daily and I like to ride females in my car. No way in h*ll I want to drive in summer time heat without the option of cutting on the A/C anymore. With that being said, I'll bring on the pics!



^Here is a pic of the used A/C compressor that I received, but as you can see it does not line up with the A/C compressor bracket. I did a google search and found that this A/C compressor was made on a Japan Coupe?

^Here is another pic with the A/C compressor bracket rotated showing you that the holes don't line up with the bottom part of the of the A/C compressor.

IMPORTANT NOTE: - It seems that there are two different patterns for the SR20 A/C bracket. Since all the blocks are the same, the bolt patterns that holds the bracket to the block would have to be the same, but the bolt pattern that holds the actual A/C compressor is different?

:EDIT: I was right about the two brackets. Pic approved below





^Here is a the back view of the CALSONIC Part # 92600 69Y00



^Here is a pic of the A/C compressor bracket that came off of my USDM lowport parts motor from a 96 200sx SE-R. I checked the A/C compressor bracket on my UK 10.1 motor and it was not the same.



^Here is a pic of the air compressor that is currently on my car with the one I tried to install. Notice how I have the clutch wheels lined up and look how off it is. I sent out a MULTI-TEXT the night all this happen asking how many different A/C compressors were made for the 91-94 SE-R's.I got a few different answers, but now I'm bringing this to the board.

This should be a good thread for people that want to run A/C. The one that is on my car didn't have any numbers on it. The sticker must off came off so I'll have to find out the part #'s. The main reason for starting on this so early is because my clutch on the A/C compressor sounds like it can lock up at any time! I'm probably gonna have to run a NO A/C belt until I find the right one.

^By no means am I a expert at this, I'm just making this thread to show what I had to do to get my A/C working. First I had to figure out if I was going to go with R12 or R134a. I need to replace all the seals and the dryer/receiver for it to work properly long term. Getting these two things are a most once the A/C unit has been opened from any area.

Buying New - R134a O-Rings
Buying New - Dryer/Receiver
Buying New - A/C Expansion Valve



^This is the evaporator core




^This is the A/C Expansion Valve (It is connected to the evaporator core)



^This is the A/C compressor.




^This is the A/C condenser.



^This is the dryer/receiver looks, but I will be buying this new.

^What you want to avoid when changing out parts and leaving in bad parts.

You will need a new compressor. and to get a hold of a retrofit kit (it comes with fittings and the proper new oil that you need and possibly a flushing agent). Make sure you get a good flushing agent as it is very important to get ALL of that R-12 stuff out. You need 1.25 times the amount of R134-A than you needed of R-12. And To be on the safe side a new receiver/dryer

^Thanks for the input. I spoke with forum member DC Scotty and he was telling me about getting a new dryer/receiver and new seals/o-rings. I will need a receiver as well? I reserved post # 2 and #3 so that I can post up part numbers that people can use to get the right parts once this thread kits rolling.

receiver/dryer is the same thing

^Where is the best place to get this retrofit kit? By talking to some more people on the phone, the A/C compressor selection by year was random. It seems that there are at least 4 different kinds out there or more?????

I'm now requesting pics of "A/C Compressors" with the part #'s, what car it came off of, what oil you are running R12 or R134a, and what year. Any extra info would be great, like the A/C compressor being OEM, replacement, or aftermarket.

Thanks,MR

I got my retrofit kit from napa. you need PAG oil. And try not to use the term air compressor. as simple minded parts people could be confused. While you are at napa ask them if they have the a/c compressor for your car and get the number off of it for comparison

Last time I had to do the a/c on one of my nxs,I rented a a/c vacuum pump and guages from Autozone.
I bought a bottle of PAG100 oil to fill the compressor,a package of assorted a/c o-rings,new receiver/drier/accumulator whatever you wanna call it,and a retrofit kit,that came with everything else.
It cost like 40-50 total for all the stuff.
It was like 300 bucks deposit,but its free for the rental,but I brought it back the same day and they just put the money back on my debit card.

Worked out good for me for at least a year or wo before I sold the car.The r134 is not quite as cold as the r12,but it does the job.

A/C is one of the few things I left to the experts on my SE-R. Nice post! Keep the updates coming.
