I want to relocate the brake booster to the front of the engine on the power steering pump bracket as shown. The car will not have power steering, which is fine with me, but another consequence is the air conditioning compressor will not fit in the stock location anymore. The attached pictures are not of my car, but show what I where I want to put the oil filter housing.




Therefore, I'd like to mount the compressor on top like on a naturally-aspirated 300D. It will also work better with the original air condtioning setup the W111 has. I'm wondering how feasible this is. It looks like the compressor might be able to be relocated simply by adding a compressor bracket from a naturally aspirated 300D and then using the thermostat housing and hoses that go to the engine so everything clears.

I happened to find a picture of an OM617 turbo engine with a top-mounted compressor, but don't know if it was an easy installation or required a lot of modification. If anyone here has relocated their compressor up top on their OM617 turbo, I'd be interested in hearing about it.
