First, the MB turbos are amazingly hassle free. They run much cooler than gas engine turbos and seem to have been made very very well... We see very few complaints on this forum compared to the number of miles and number of vehicles equipted with them.
One of the few hassles concerning turbos is the lack of hand space when dealing with stuff under it.. like the starter...
But in general turbos are made to go with Diesels... some day I hope to redo my 240 engine with turbo pistons, oil squirters, etc, and add a turbo. The are available in India stock from MB that way.
