Sanden compressor conversion brackets for sale

[Layne]

Hey guys,
I haven't been on here in forever. Good to see the classifieds is still "closing soon". Some things never change.

I have a very small one-man BMW restoration shop that I call L.C. Wylie & Co. and I also make and sell these brackets to convert your air conditioner to a modern Sanden type compressor. The original compressors are inefficient, expensive, and very hard to find a reliable new or rebuilt unit these days. Sanden compressors and replicas of them are reliable, efficient, and easy to find. The only E34's these would work on are M30 535i's, M20 525i's, and possibly M5's if you delete the air injection pump and install an M30 wing cell bracket. Not totally sure about clearance to the coolant pipes on the M5, but I'll get customer feedback on that eventually. This is not needed for M50 and M60, those stock compressors are already pretty good and not so expensive, unlike the older models.
My bracket attaches to the oem aluminum wing cell compressor bracket that should already be on your car. Installation is very simple and the hardware is included. Just bolt on the bracket, and bolt your compressor to it. I've been selling an M30 version for a while now and just finished developing a new version for M20's. Photos below show the prototype installed on an E30 325i. I sell them for $150 and that includes shipping within the 48 states, and the mounting hardware. Worldwide shipping is available at additional cost. You can buy online at the website below, or follow me on facebook or instagram. It'll be a couple weeks before the M20 models ship out, but you can go ahead and buy any time.

Glad to see you here again. Any idea what changes might be required to get the E34 AC to cool more efficiently, effectively, and without triple the refrigerant capacity of a normal car?

You have a M60 right? So it's factory R134a? I never had a minute of trouble out of the A/C, except the compressor clutch bearing failed once on my old 740iL. They work fantastic. Might help that I'm comparing it to 80's BMWs and not to brand new cars.

M50 now, factory R134a, overhauled with new seals, dryer, and condenser a year ago. Works well but not as good as newer vehicles, and hisses.

Are you working to produce the same for the M/S5X line of engines, E36/E39 fitment?

No. Those have a Nippondenso compressor as far as I'm aware. They work great are are not expensive or hard to find like the old ones. Plus they are rigid mounted with a serpentine belt and a tensioner. It's a much better setup than the older cars had.

Dude yess!!!! I havnt been on here in a while either and just so happen to see something I actually need!

my e32 735’s compressor finally bit the bullet. I’d love to change over to one that’s more “proven”, any advice on the swap as far as the lines? Are there fittings or would a swap require custom lines?

Layne,

Nice website and very cool product. The A/C in my '91 has been inop since I bought it. Getting the A/C working has been on the wish-list, but I have never done it because I have always liked the idea of finding a way to integrate newer components that are more efficient/lighter if I can find a way to make it work. Maybe now I will focus on this and figure it out. Very cool.

The lines are pretty easy. The smaller one should bolt right up to the new compressor. The larger one has the wrong size fitting on it. So you take your old line to a hose shop and they can reuse the metal pipe on the fender and attach a new piece of hose to it with a different sized end. It's pretty cheap, should be around $25.

Beyond that, you need to flush the system if it hasn't had pressure in it for a while. I like to replace all of the O-rings. The interior ones are probably pretty difficult to get to in an E32 though. Best to get a new receiver/dryer. In most cases you need a better condenser to get satisfactory performance when converting to R-134a, but not on the E32 (or E34). The factory condenser is huge and they did not change it when the factory switched over to R-134a. It works great. And of course you want to leak check everything before filling it up. Pressurized nitrogen is the best way to do that. You can get an AC shop to leak check and fill it up if you don't have the equipment.

I'm doing an AC job on an E34 M5 for a customer. Turns out my bracket is a great fit even with that radiator hose that hangs down low on the right side. This is with the air pump deleted and an M30 wing cell bracket installed, but it might even fit with the air pump.

Does anyone have a link to the compressor that we need to replace the original?

Bump!! I’m working on my AC now on my 1991 M5! Need a compressor & bracket!

Glad you found this - I was going to direct you here in your thread in the main section. Layne will get you sorted

Do you have a bracket for the M70 v12?
