i've already made this post but wasnt getting much response to im trying posting here.

so i've had my car for about a year now, bought it without aircon and was happy with it but i think i'll be keeping it for a while to come and want to put the air con back in, i want to know whats involved in doing this, parts i need etc. the car currently has the climate control thing and everything on it works, except for the fact there is no actual aircon system in there

Yeah. You got better info in your other thread

My point being is it's not easy. Not even for some people who work on car AC's for a living.

Skylines AC was sophisticated for it's time but it's different from other vehicles

Getting the 2nd hand parts and putting it together . Do they even work? How would you know ?

Then find out some components need replacing. Thermister, receiver dryer, condenser, all the sensors, using correct ohm resistors

There will also be a level of fault finding and rectification once it's together.

I hope you have the AC manual with wiring diagram and fault codes/diagnosis The AC diagnosis will give you good information and point to the issues

But if your not an AC / Auto elec it's going to be a bugger because you need an understanding and be able to trace wiring faults and remedy.

Somethings your better off not doing DIY.

Why do you think i'm posting here if i knew how to do it myself? i asked for a list of parts and wanted to know what's involved in the process, i know its complicated and i never planned on doing the entire thing myself but i wanted to get an idea of what i could get myself and what i could do myself and then once majority of it is done give it to someone who knows what they're doing to finish up all the wiring/little details. If i wanted to simply give my car to someone else to do the entire thing for me and spend a fortune in the process then i wouldnt be on this thread, and yes your initial information was totally useless because i asked for parts and a process and you told me to go do it myself or get someone to do it, please learn how to read and answer a question while using your brain before you write a reply thanks

yet again your info wasnt helpful, i live in qld and theres plenty of places i can get parts nearby, what i asked for in the original post was a list of parts i needed for this, for example what parts i need to get new and what i'll be fine with second hand and whats involved in the whole process, i have gotten a response in my other thread although i'd like more than one source of input just to see if theres anything he missed etc, unless you know whats involved and a list of parts i need or a source with that information then stop wasting my time and get off this post

No photos posted on what's already in the car so how can anyone give correct advice.

For all we know it might only need a compressor but then again the whole evaporator unit may be missing.

If the evaporator is there, perhaps it's rooted and could be a reason the previous owner ditched the aircon .

Too many unknowns.

im being rude because he was being rude lol, and jiffo maybe people can just ask those questions i can give a response? i dont plan on writing out every single detail of my car and hope some of it is relevant information haha, im assuming the previous owner pulled out the AC because there used to be a big single turbo rb26 in it, and i can provide pictures of the engine bay and all that if needed but from what i can tell nothing on the interior of the firewall has been pulled out just all the engine bay components

So you're saying the evaporator is still in position.

Did previous owner seal the high/low pressure fittings at the firewall? This is vital or contaminants will have entered the system and you'd be spending a lot of time and effort on a blocked TX valve as a minimum.

The engine bay components are the compressor, condenser/filter dryer and the connecting pipework.

There should also be a thermo fan in front of the left side radiator.

None of this is much use though, without the electricals. Hope previous owner left all that intact.

Mounted on the bonnet latch strut should be the ambient air temp. sensor.

In one heater pipe at the firewall should be the coolant temp sensor.

Inside the car on top of the dash should be the sunload sensor.

If the evaporator is untouched its sensors will still be there.

It's a complicated system.

Best chance is to find the complete setup from a 32 half cut.

so to update i couldnt find any electicals because i wasnt too sure what to look for, the fittings weren't sealed, im fairly sure i found a sunload sensor on the dash and couldnt find the air temp sensor, i'll post some pics as well

Here's some photos from my 32.

The ambient air temp is that cad. plated box and may not be exactly as this one is due to the fitment of a magnificent horn.

The thermo fan can also be seen.

Filter/dryer is attached to the condenser.

High and low pressure fittings at firewall. These are going to cause you a headache as yours were left open to atmosphere.

Suggest you have a talk to an aircon. specialist to see if they can flush your evaporator.

Explain your situation, it's bound to have happened previously.

In fact I gave a mate an under-dash aircon unit for his Statesman way back when. Unit had been kicking around in the dirt for years yet he installed it and the experts made it run fine.

Your electricals will pose problems if they've been hacked off. You may have to strip back the various harnesses to find the remnants of circuits.

awesome, well for starters i'll go get it checked out by an aircon specialist about the evaporator and after that i'll get all the parts i'll need and either install it myself and get all the little things sorted out by a pro or just get someone to install everything in one go

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
