My W123 with om605 turbo - Dieseeelstar - 08-31-2015
Hello! so i bought this w123 and my goal was to have a cheap and reliable daily driver, so i decided to find a om605.
Sadly i dont have many pictures throughout the project since everything was pretty easy and straight forward surprisingly, but i will try to help you guys if you have any questions.
Engine
Engine
Driver side engine arm from 601 makes a perfect fit
Passenger Side Also from 601 fits perfectly
And a bad picture of the car atm.
Im thinking about turboing it but were is the easiest place to make a oil return?

Are the om601 arms from a stock 190D? What can you get a om605 turbo engine for price wise over there? I'm looking to import one eventually for my s123.

Ye i quess so i had them from an old engine i had before i can send you the number on the arms if you want me to =), prob around 500-600 euro theyre pretty pricey.

Was bored today so decided to adjust fuel screw to prepare for the upcoming turbo convert, were is the easiest place to make a oil return for the turbo?

The stock oil return for turbo engines is also there on n/a engines. It's near the 2/3 cylinder just above the oil sump. Just drill it with a 12/13mm hole and m6 at both sides. That way it's just like a turbo engine.

So i found a turbo engine instead and decied to put it in so heres the result, but i have a problem i got no boost and it almost have no power i have connect the wastegate to direct vacuum.
The ip is from a 605 naturally aspirated with rs 201 and turned up max on the fuel screw.

EGR valve leaking ?? Try removing it completely.

Are u using thr original turbo? Ive the same engine in my cklass. Test connecting the wastegate to a vacuum line of the engine, not to the pressure site oft the turbo.

i had that problem too dieseeelstar, i dont know how much electric you have, but in my case the car was going into limp mode without showing it. A hose have been wrong connected to the magnetic valve before the wastegate. Maybe check that...

I have a mechanical ip so no electrics and The wastegate is directly connected to The vacum pump so it has vacum all the time.

The original garrett turbo has a vaccum controlled wastegate , not boost controlled like the older ones, try attach vaccum when engine is running to see if it moves.

Seems to work now i had a vacum leak.
