Hi, so my series 1 r33 GTST's AC decided to die in California's hot summer. I've been finding replacement parts and its been a nightmare. I've been thinking of rebuilding the ac but I heard its pretty expensive and It's hard to find a place here in san Francisco. Does anyone here have experiences or alternative to fixing the compressor?

I recently went through this with my w34 stagea and was unable to find new genuine or aftermarket options. I ended up taking a punt and buying 2 used ones off yahoo japan, and the first one I fit worked so I have a suspect spare.

I suspect AC compressors are going to become one of those impossible to find parts over the next few years until someone works out a non genuine alternative including mounting

Hey,

Sorry to hear, I'm not trying to be a dick, but do you know that it is a compressor failure, or are you just speculating because your A/C isn't working?

Well, the clutch is apparently not engaging at all and has a huge gap, it also does have an activating click when turning on the ac. But regardless the compressor needs to be changed anyways

Yahoo auction is actually a pretty good idea. do you know if stagea's compressor will fit the gtst?

Possibly...there were differences across R33 air cons and I'm not sure what they were. Late R33 and Stagea are *apparently* the same.

The mounting is the same, the wiring is either the same or interchangeable (1 wire) but the fittings to the car can vary.  I'm sure others know better than me.

You can confirm the exact part# using your VIN through FAST or parts websites.

Clutch <> compressor. Compressor could be fine. Probably is. The compressor and clutch are going to be common with other cars. Take it to an auto electrician, particularly one who also does air-con regassing etc.

And how can it be hard to find someone is San Fransisco to rebuild a compressor? I live in a backward city in a backward country where we all hang upside down from the ground, with a population of only a million or so people and I can probably come up with a list of 5 or 6 places that I would be able to get an air con compressor done. You have SF (pop 1M, LA (pop ~4M), the rest of California (~40M), every other city on the west coast, every city everywhere else in a country with 300 million people.

you're right, I might've not looked hard enough, I will do that this weekend when i'm free of work

It is possible the clutch isn't engaging because the air gap is too big. The clutch air gap is adjustable. The clutch air gap is determined by a stack of shims of varying thickness. You can change the air gap by changing/removing shims. You also need to be sure the clutch coil magnet is getting 12 volts when you turn your A/C on. And you need to put a set of manifold gauges on the system to see what it is doing. If the gauges indicate the static pressure in the system is okay, and you are getting 12 volts to the compressor and the clutch air gap is within specification, then and only then can you rule out the compressor while watching the gauges. Hope that helps

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
