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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
