I was wondering if anyone who frequents this forum has Modded their Mercedes Diesel, OM 617 and 603's in particular? Mild turn ups?

How do you turn a 603 up? Is it much like a cummins where you first open air passages up for better breathing(ie. exhaust and intake tubing) ? ? route air up front to an intercooler? Turn up the injection pump?

Any documents or websites out there on this kind of stuff? Just interested.

Thanks a bunch.
