I bought the car like this, but the previous owner installed a on/off switch on the dash to turn on the AC compressor. I believe this switch is wired to the engine bays fuse panel. When i switch the AC compressor on, i feel it dragging the engine and it makes a grinding noise.

My question is, should i have the AC compressor rebuilt? is that a possibility? or should i buy a new one?

Yeah, it is possible. But like many related things (ie, alternators), it's getting harder to find anyone who does and will, given the change to just throwing shit away and replacing with new cheap shit from Chinese factories.

If you want to pursue the option of rebuilding, you'll have to dig up an auto A/C specialist or three to find out whether they still do.

If you really want good AC consider the frenchies kit.  All modern gear, works much better and is lighter.  But it is $$$$$$

I'm looking at it now. The price dosent seem that bad.. a new R32 GTR AC compressor is $500-600 here in the states. It looks like they are using a different compressor though from a Toyota Echo.

I actually think its really good value for everything brand new plus the conversion work all done. Just its more than buying just a compressor.  The billet bracket is a work of art. 

This pick alone, tells you how many decades you are moving forward

I did not need to see this! :D With summer quickly approaching...

Did you just get the compressor with the bracket or the full kit with fan and everything?

In what way is different to the old OEM one?

I got the full kit.

 

The compressor as above is much smaller and lighter.  Also quieter.

Bracket is visually mint and much lighter.

The dryer and heat exchanger(rad) are one unit. Also smaller and lighter.  Much more room for an oil cooler.

The fan I got was a bit Meh and I might change it.

 

And above all else it is more efficient, tested a good 3-4 degree's cooler than the old system, which is a lot.

Disclaimer though - It wasn't a back to back test given different days. It really does feel colder though(always).  And this example is in my car with that crusty looking old compressor, not new vs new :D

The website said you need a AC technican to swap it in. Is that true? How did you fill the refridgerant? Was it easy to install? 

If i just got the bracket and the new smaller AC compressor, would the other components be compatible with R134?

I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications.

This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.

There's probably an underlying issue with the A/C system too.

I recently fixed mine, now it's fully control by the Haltech and car's factory HVAC controller

      And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.

      Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.

      Deeve, I don't suppose that you've made any progress on this? My Stagea has the exact same problem, and just like you, I've read through as much as I can online, with no real progress. My car isn't throwing any codes at all, which is a little frustrating. I've changed plugs, checked the wiring and harness. A new MAF gets here next week, but I'm not hopeful it will solve the issue.
