The only reason I suggested closing this thread is the last update was 5 months ago...and then other discussion and sale options were popping up. I hope Jim is OK but is there anyone, George or Jim, that can provide an update? If it doesn't seem possible again, let's just close the darn thing and try again later. With as long as it has been, do we really believe that all those that voted are really still in anyway?

...just a thought.

I had good luck converting my standard a/c to R-134a last summer. I was surprised at how well it worked. Car is in storage, so soon I'll know if the charge held through the winter. The tech who did it said he charged by weight, not by pressure readings. He did a system evac, changed the receiver dryer and refill of R-134a by weight using the standard conversion ratio, if I remember correctly.

Hello guys,
Just see this thread right now. I'm not sure I need a full new kit conversion because my AC works perfectly and it been converted to the nex gaz yet. But I have a probleme: the dehydrator (not sure if it is the word!?) has a leak. If can just change this part, it would be better.
Does any body now where I can find one?
In case I don't find one, I would be interested by a full new kit...

I think you are referring to the drier. It's the Coke can sized thing in front of the condenser. They're common sources of leaks and, at least here in the US, quite cheap, On the order of $10 - $25. Maybe you can order one from Rock Auto. You will have to have your system evacuated and recharged when changing it. Do Not open the new drier until the moment it's being installed or you'll need another new one!

If you just want it to "work" you just need to make two hoses that go from the compressor to the condenser and the cross over tube. The JZ hoses are the block style and the Mk2 stuff is standard tube O fitting. I just cut off the crimp fittings and welded a tube O fitting on the JZ hose end. You can then make a hose with standard fittings For wiring the VVTIs have the 4 pin AC compressor connector. Find the wire that goes to the clutch and connect it to Mk2 wire.

If you want to upgrade things and make an AC kit you can buy a generic condenser and dryer on ebay that look almost identical to the ones in the kit. The condenser I have in my car is a 12x24 and the dryer buy one of the smaller ones. Most of the hoses that came in the kit are recreations of the stock ones so technically speaking you don't need them. You'll need to plumb up the dryer and the two lines from the compressor.

You don't even need to go that far. Just take the stock mk2 lines, and whatever you have of the JZ ones, cut the crimp fittings off (but be very careful not to damage the actual connectors underneath, slip the JZ connectors for the compressor side into the same hose, fit it all on the car and clock everything right, and mark the line to connectors with some pen. Then take it to an AC shop and they can cut some new hose, slip the mk2 and JZ connectors onto the new hose, and copy the same clocking you have marked, then use new crimps on the old connectors and it works like a hot damn.

That is the best way to do it By weight, if you do it by gauges you can be off as much as 4 oz. After the charge is correct then you can check to see if you have too much or to little oil charge, it must be about 90 degree's outside to do this if the compressor is over a 140 degree's add 1oz oil and check again, if the compressor is under a 100 degree's your getting ready to slug it you have too much oil. Any question pm me.
