update?

Also, what type of oil and how much did they use?

Can greatly affect the life of the compressor.

Hi Luke,

After inspection, it looks as though the AC compressor had overheated internally and seized.

The A/C specialist suspected the pressure's were too high due to the older original condensor design as the system was not designed to operate on R134a.

We used PAG46 oil in the new A/C compressor. Between 160-180ml.

Did they replace the reciever drier and clean out all the lines? Cause the metal shavings from the first failure will kill a new compressor very fast

Yes they replaced the reciever drier, cleaned out all the lines, even replaced one. Also did the evaporator, TX valve under the dash. Cleaned the lined out with Shellite. The works.

Hi All,

OK so here is the update and where I am up to.

I have 3x GTR R32 A/C compressors. 2x Zexel (original one off the car that leaked and a second hand working one I bought recently) & 1x Valeo (the new one that failed)

The specialist pulled apart all 3 of them and made 1 really good one. Looks like he decided to use the Zexel housing.

180ml of n8 denso oil has been put in it and we fitted it to the car.

Next we have removed the old condenser from the car, drilled out the rivets and removed the mounting brackets to be reworked into a new universal condenser.

The reason for using a new universal condenser is because it was suggested that the pressures with the original condenser was to high after retro fitting with134a gas.

The old condenser was a 'Serpentine' type and the new I bought is a much more efficient 'parallel flow' condenser.

Just waiting for the rain to clear so that we can fit it to the car, then have to clean all the lines again before recharging the system and it should be ready for winter lol.

Pictures to follow..

Hmmm.

I have a feeling it may be over oiling.

I have run 134a without any issues.

Even in temps as high as 40°.

Do you know how many mls you put in yours?

Paulyp, did you modify your condenser fan to turn on with the air con?

Hi Dark26, Yes that was modified to turn on whenever the air-con was running.

Will check the fan before re-fitting to make sure its still ok.

cant remember.

Would have been around the 30ml mark.

But, I will check the workshop manual and let you know what Nissan recommend.

Hi all,

Just another update for everyone.

We have finished fitting the AC about 2 months ago and its working well.

Went through alot of effort to fabricate brackets and have hoses made to fit. Also had to modify the standard cooling fan to clear the new condensor.

Please see below pics and it should give anyone thinking of doing the same a good starting point.

for what its worth, if your going to goto the effort of modifying or making up new lines for an ac system, you may aswell replace the compressor with a universal aftermarket type and just get the lines made to suit, and on the topic of higher pressures, you should have a low and high pressure switch installed to make the ac cut off if pressures get to high, yet a newer style of condenser will cool better so lower pressures a bit more and keep the car ac abit cooler.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
