Thread: 93 NX2000 AC Compressor Interchange - B14?

This is very 93 NX specific so I hope you don't mind this goes here rather than technical:

I have a 93 NX2000 manufactured 12/92 retrofitted to R134a (looks like quality hardware FWIW).

I got some High/Low Gauges and found my low pressure side is too high (around 90 psi+ at idle, around 45psi at 4000rpms) and my higher pressure side is too low (a straight 150psi all the time). Also my AC is cold at 4000rpms but useless anywhere lower and it's getting worse so I believe my compressor is on it's way out.

Can anyone confirm what I've found on a few sources?

The B14 AC Compressor from 95-98 on BOTH the 1.6 and 2.0 is interchangeable with the 93 NX2000 AC compressor (93 NXes made from 7/92 to 12/92, apparently the older 93s had the 91-92 compressor).

They're all identified as Calsonic DKV14D

Original part number appears to be: 92600-68Y00 (rated for both R12 and R134a)

92600-68Y00 - Nissan COMPRESSOR

which is replaced by: 92600-68Y21 (officially rated for R134a as it was all they were doing then anyway and also titled Calsonic DKV14D)

Autozone FWIW also shows the same compressor for a 97 B14 1.6 as for a 93 NX2000.

If this is true, this compressor will be easy to find. Will my lines bolt into it? Am I crazy?

Here is my shopping list BTW for the setup from RockAuto - I'll report back:
New Expansion Valve
New Dryer
New O-Rings
PAG Oil (100?)
Professional flush/refill after the new parts are installed

Thanks in advance - happy to post photos of the procedure if there is interest.

UPDATE: Pulled a compressor from a 97 1.6 sentra, confirmed it is an absolutely identical DKV-14D with the exception that it says it is R134a only. Bolted up perfectly.

nice thanks for the update I need to track one down and do the same thing

I did just the condensor first and ended up with the same readings/issue, no cold air, everything runs OK and the numbers look ok-ish.

I just got in from installing the expansion valve. AC is very very cold with now - the charge is a little low as I need one more can of 134a, but that probably explains why it's working so well. What seemed to really do it was running the shop vac on the condenser - it had some liquid trapped in it which I did while getting to the expansion valve.

Basically, without a flush I'm concerned this is just going to blow itself up again. at that point I think I really have to replace everything under the hood with clean stuff - at least those that can't be flushed to the point of spotlessness - and get another compressor.

I'll report back on the situation.

Topped up one more can, so far so good so cool. Again, this should be flushed but I think it might be beyond that at this point. I may just have to replace everything at a later date. I can confirm however that the compressor is identical - and since it's a B14 it never saw R12 - so pull your DKV-14D compressors from B14 1.6's and 2.0's at will.

Still Cold. Starting to not need AC anymore in SoCal. If only I can nail down my squeaky belts - but that is for another thread.

Great job of updating this for us...this is some good info for us guys who MUST have AC

good to hear iam thinking of adding ac back to my ride once summer hits again
