E270 CDI Engine transplant

[jyobeb]

Hi. I'm from India. I own a large Indian SUV, the Tata Safari, a good but rather underpowered car. I happen to have a mercedes E270 cdi engine lying around, 2700 cc, 5 cylinder , 170 hp. This engine is missing an ECM, and I am trying to procure one for it. Suppose I do manage to get an ECM, can I fit this engine onto my car without too much technical hassles or is there a lot I need to watch out for. The fitting I will get done but will the car run within this setup?
Any help on procuring the ECM will also be appreciated. Even the part number of this ECM will help.
Thanx for your help in advance.
