Hi all,this section is very interesting and I spent allot of time reading your posts.

I have a Mercedes w201 2.5 diesel 1989 model.It's Europe version because I'm from Malta.The engine has only 68000 KM on the clock.The engine is in very good condition starts first time no black smoke and it's strong for a 2.5d.

Now I am planning to add a turbo,I don't need to much more power but what I'm looking is to add some more torque.

If I add a turbo how much psi can the engine take without harming the inner parts?
