It spools up pretty quick now, so even around town it has much more pep, even w/ the AC on MAX. It seems like my impeller has been dragging all these years, robbing needed power.
If you don't want to rebuild yourself, Turbo City in Orange, CA will do it for you for a couple hundred bucks.

I just had the regular turbo kit w/o impellers.
617 engine '85 300D CA. 187,000 miles (bought at 93,000)
The impellers seemed fine, no nicks or damage.
I used plenty of "Bead Blaster" and cut the head off a bolt with a grinder. I didn't get the special tool kit, though there are snap rings deep inside the turbo body that need replacing, and it was a PITA with just 2 ice pick tools. My snap ring pliers weren't long enough. If I was going to do another I'd make some tool for that.

First & foremost :
_BEWARE_ the ' cheap Mercedes ' !! .
I personally love my W-123 300CD Diesel Sports Coupe , I'm on my third and hopefully last one , it's co$t me wayyy too much Lolly over the years but well worth the $ IMO .

You're right on target Chip ;
R-12 cools ever so much better .
To revert back you'll have to open up and flush the system of the old R134a residue and it's oil .
They make and sell simple kits for this , there's mucho labor involved but well worth the effort unless you break things in the process .
Basically , you open the inlet & outlet commections on the evaporator and condenser , connect the flusher's hose to one and begin squirtinjg the flushing agent in .
Marvel at the amount of metal chips , old oil and general funk that comes roaring out the other end and remember I'd warned you to lay down BIG trash bags and bag the open outlet with a large , clean cloth....
Those German wool carpets wear like iron and are pretty & oh so soft when SWMBO takes her shoes off but after you've ruined them with AC spooge , they're *very* $pendy to replace .
Unless you've done so already , replace the expansion valve and of course , the receiver-dryer too , cheap insurance .
New oil in _before_ you begin re - charging it .
Seriously consider the Japanese Sanden Compressor up grade ~ if you can find it with the brackets , please let us know , I didn't save that site .

You'll be pleased to find you only needs remove the arm rest then the interior door panel to do this simple job .
Best of all , the driver's (most often worn out) side one is the _very_SAME_PART_ on the rear driver's side door (the least used/worn door) making finding a *perfect* used piece a snap .
Be aware there's several Phillips screws that will be wanting the correct size screw driver , not any old worn out tip Chinese thing you have rolling 'round your tool box .
To remove the trim panel I use a GM window crank tool , it's made of 4" wide stamped sheet metal
with smooth edges and so is *perfect* to *gently* slide between the panel and your door & lever loose the plastic clips ~ once they're loose all the way 'round you'll have to flex the panel so the clips are proud of their holes whilst you slide it _straight_up_ to release the clever (= PIA German over engineered) clips holding the upper ends of the map pocket to the door proper .
If you go this far in and find only the roll pin has slipped out , use a same diameter cotter pin slid in from above , it'll work and never slip again .

Maybe start running penetrating oil in around the studs now to help loosen them. If you can reach them, give them a loosening twist now to see how many are stuck. Bill in

The engine is now clean on one side, the manifolds are in along w/ the gutted CAT. I took apart this turbo, after making marks for later placement, and found gelled oil behind the impeller and throughout the housing, on the intake side, and built up carbon on the exhaust side, so obviously this turbo was leaking oil and needed a rebuild.
I'll put the turbo back together today and install.
I added some pics: engine, manifolds & CAT, turbo taken apart before cleaning intake & exhaust

Another question -- did you use the mercedessourse tool set? Are special tools necessary?

There were a few PITA moments with the turbo, yet pretty straight forward if you follow the instructions.
I added a couple more pics.
Here's a video from Mercedes Source on turbos:

I used the Mercedes Source turbo rebuild kit.
