Ok, so you got a car. Now you have to ask yourself, its this a real project car, or is this just a hopped up get around car. If you still have a stereo and more seats than one, then you have a hopped up get around car. This is dedicated to people building a real project car.

Originally, I had AC on my car, just to see if it would work. Word around the block is that its hard to rig AC with SR20 installs. I did it, it wasnt. Now comes the time to rip all that hard work out. Get rid of that heavy compressor and mounting bracket. So, with that in mind, lets get to work!

The car used in this tutorial is a HS13 with SR20DET install, your car may differ. NOTE: DO NOT DISCHARGE FREON TO THE APTMOSPHERE, GET YOUR SYSTEM DISCHARGED BY A PROFESSIONAL.


Step 1: Take a look at the accessories being driven by pulleys. Get familiar with them, as you dont want to cut any of your power steering lines.


Step 2: We gotta take the belt off the ps pump, due to the triple pulley system the SR20 has. To do this, we have to loosen the tension bolt located below and behind the fact of the ps pump. Loosen this, and the nut on your crossbolt, then pull down on your ps pump, and remove belt.


Step 3: There, now once we have that belt off, we can go ahead and get the belt off the AC compressor. To do this, we need to loosen the idler pulley. Do this in the same fashion as we did with the tension bolt on the ps pump. Loosen bolt 2 first, then loosen bolt 1 until belt slides off.


Step 4: Once the belt is off, we can take off that pulley all together. Just remove bolts 1 and 2 and remove pulley.


Step 5: Remove the lower support bolts on your AC compressor. There are one to two more above it, I had one, as I was lazy while installing it.


Step 6: To gain access to the work area above the AC compressor, I removed my MAF. Easy to do, just loosen the crimping mechanisim, remove support bar, then pull out.


Step 7: There are AC lines running to the top of your compressor. We need to get them off. You'll need a bit of an extension to reach them. They're easy to spot, below is a picture of one of the lines removed.


Step 8: Ok, you got the ac lines off your compressor. Now you have access to the top bolts. I put a jackstand underneath my car, supporting the ac compressor, so that when I took them off, it didnt fall to the ground.




Step 9: Tada! Removed!


Step 10: You have the brace left bolted to the motor. Lets get that off. Just simply unbolt and remove.


Removed!


Step 11: The condenser will be removed at another time, when I do my FMIC + Radiator upgrade. I did however remove the fan and ac lines connecting the condenser. This is rather straight forward.


Picture of my Dad removing an electrical clip for me, I have super big hands and some stuff is hard to reach for me. He and I were both doing auto work outside, he was assisting at times on my project.


Step 12: Now that you have come this far, you can remove the AC receiver drier too =) Simply unbolt, no trick to it. There are AC lines on top of it you will need to remove.

Step 13: Remove the AC lines running to your firewall to your evap. You may need to do some navigating to get the lines out, I just used some bolt cutters and chopped my way through as I have no intent on ever putting this back together.


Only things left to remove are your evap and condenser. That will be covered at another time. Enjoy =)

i see you spent time doing this but these aren't really the forums you should put it in.

good stuff; ill let this get some momentum in here so people can read it then ill move it to the tech faq

Actually it would go here. Thats why there's two sections under automotive: 1 for basic conversations and 1 for technical stuff. This is technical.

Ah thx. Yea, I got crazy with the digi-cam and decided to document something for a change, instead of just doing it. Took a while, as I had to hit my hands with cleaner every time I wanted to touch my cam, so I didnt slime it with 240SX gunk, but overall, I'd say the shots came out ok =)

damn that 240SX gunk. Now if it were say 200SX gunk that'd be a little different.

Awesome tutorial. You know what they say about guys with big hands. Big gloves.

that writeup is great man. you should mos def post that on some 240 or nissan forums. its crazy cuz the steps are kind of similar to taking the AC off of a VG. the mounts in diff places, but the lines run the same routes. it does save a lot of weight though... i kind of miss it sometimes in texas summer heat..........

I'm thinking about posting it on NICO, but most of the people on NICO already know how to do easy stuff like this.

In a couple years, when I return from Germany, I plan on doing a SR20DET rebuild write-up, hopefully being the first person to do one in english.

Awsome faqs. Good when I get my 240.

Moved to Tech FAQ

Damn, hard to believe that was only two years ago. Feels like so long. I havent seen that car in quite some time, it'll feel wierd when I get back to living in the USA in March and seeing a SR20 under the hood. Well, at least until my CA18 rebuild is done, then I'll finally be rid of SR's, for good...

Funny seeing this in the "FAQs". Should go under LAQs, as thats probably the least asked thing I get from folks at my garage. I usually get questions like "Whats this ticking noise?" or "Why does my car idle like ass?"

I've so got to get me a 240SX. The car looks easy to work with.

Eh... SR's blow to work on. Everything is in the way. Changing the turbine flange gasket is a nightmare. KA's are a pain. CA's are probably the easiest, but still not something I do for entertainment value.

Not nearly as bad as working on those retarded boxer motors that reside in the Subaru's you worship, but still not a walk in the park.

Quoted before hellbent quotes it.

At least you can access it fairly straightforward from the front.

I get limited side access... only way to get to my compressor is from below. From the looks of the pictures you seem to have some access from above. Well, maybe not.

Nice stuff and I really like how you mentioned the freon warning.

@Demon - f**k u demon, Iam stil quoting it.


@Floh - so does that mean u dont like Porsche motors

To drive, yes, to work on, no.

Haha id forgotten about this thread. Well if all goes well ill contribute my very own "how to" thread here this weekend, its the one i mentioned to you awhile ago floh

subaru motors hard to work on, what are you talking about? tis easy only thing you have trouble with is changing sparkplugs... removing the AC would take me about 15 minutes...

Thats the ac, he said motor. Working on the motor is a B*TCH

Wow, if i'd know this was in here, I would have removed that stuff long before I ever did it. You should do a stage two with the remaining AC stuff or other items like that water reservoir for the windshield and cruise control

very great floh

March? Cool but I thought you where going to Africa or some shit for a few years? I distinctly remember cracking a few beastiality jokes about it, and I never forget a good beastiality joke. ever

The Africa deployment fell through, something about lack of funding or something and I ended up getting screwed out of my slot. I did, however, end up going there for a short time (15 days or so) for support. Shit was fun but after that experience I was glad that I didnt go for the full 3-4 months.

eh, maybe when I am within reach of the car I will, but that thing is across an ocean right now.

Ey, long time eh..

I would do this, as I do need the weight saved.. But Aussie summers are way too hot without it.. Great tut man.
