Please educate me on turbo charger. I bought a KKK turbo charger part # 002 096 9899 and it supposedly would fit a 300SDL. They are different when I compare it with the one I removed from the car. The old one is about 1" longer with AirResearch stamped on it. These are the main differences.

1) It looks the same with all the fittings, i.e. it will fit the space and mountings.
2) It is 1" shorter. I can make do with the in-take boot if necessary, so not an issue.
3) It seems NO vacuum line needed. I cannot find the inlet. Why? What is the vacuum for? Will it perform the same without the vacuum line?

Some pictures with the turbo side by side. Would it be compatible? The new turbo spins better and seems to be less oily inside the turbine. The problem I had was the engine was blowing excessive smelly smoke and very irritating to the eyes.

Any help is appreciated.
