Or just convert the system to R-134a (DIY somewhere on here (about $500)) and have a nice working system for the next 10 years.
    There's no need to do a full conversion. My Porsche 924S (which has basically the same AC system as the e30) was obviously an R12 car. The stock Bosch/Denso compressor will work fine for r134 as long as you fully drain the old ether-based oil and replace it with the appropriate amount of PAG. The only things you actually need to do are replace the ports to r134 spec and replace the dryer (which is cheap). Make sure the system is totally evacuated and charged to the correct pressures with manifold gauges (NOT the quick-AC stuff you buy at the store).

    Your stock condenser and evap will work fine with r134. My 924S blows colder than my WRX, my late-model CX-9, or my Sequioa. I was freezing my ass off last week on those 100-degree days in this car.

    Yes, they say that r12 lines have more permeability and could leak r134, but that's really not true assuming the system holds sufficient vacuum. Try a basic conversion for the price of a $30 drier (with new o-rings) and the r134 ports before you go all-in with new everything. As long as your system isn't currently leaking, it should work just fine. If it works, great. If it doesn't, you're about $20 worth of r134 at wal-mart and THEN you can drop $500 to do the whole system with new stuff.....

    Just my 2 cents...YMMV.

    I have couple of 14oz R12 cans. Would like to have my system vacuum tested, pressure tested with Nitrogen and charged with R12. Shop recommendation in DMV area please.

    No clue
    But when I filled it up with r134a it cools pretty good
    But I have an issue where my compressor cuts off around 2500rpm upwards
    And only renegades when the rpm drops below 2500
    So let me know if you do find a local store :)

    Plenty of Shops in the greater NoVa area that specialize in BMW that can top off an R12 system.

    Was your system converted to 134a when you got a can of that stuff from the auto parts store, or was it still R12?

    I know there is an alternative to r12, that works with the OEM parts

    But you'd still need a shop, or someone with a vacuum machine to suck out the old freon

    See above post, you can't buy R12. I think you can source some reclaimed R12 from AC suppliers, but it is truly expensive and if your system is leaking, its a lot of money wasted. If your going to be making repairs to the system, you may as well convert to the newer refrigerant to save money and make the system serviceable years down the road.

    A/C Recharge Shop in DC Area?

    The A/C in my '91 318i is not as strong as I'd like it to be this summer, and I think it just needs a recharge. Have any of you come across any good shops to do the work in the DC area? I'd much rather go to a place someone has experience with than pick one off the internet.

    Thanks.
Working...
