If you're converting from the old system to the new one, it's expensive to say the least. I got quoted ~700 to change the entire system. Don't just buy that cheap stuff that supposedly works with the old system cause it will work for a little while before damaging your system. A few people over on zcar have done the conversion, they will probably have more info.

I've heard it's just a matter of a couple of fittings, but that just doesn't sound right to me. It'll probably be a bit costy. I'm still running R12, but don't even have the belt on now. Just living with the windows down and going 90mph wherever, and I live in Arizona... ;^)

If I lived up in wheat country, I wouldn't even bother...

heh well i keep going back and forth..one day im sayin ill take the whole damn system off...nother day im sayin ill charge it...i dunno l....ill just get it checked and properly charged...i guess messin with that can be dangerous i hear
