it's the old 1984 Mercedes 300D automatic tranny diesel what is the deal with the Turbo on old diesels being or not being EMP proof? I always thought the old ones were EMP proof like on the original Cummins and the late 70;s and early 80's Mercedes, but I just noticed that JWR on survivalblog says repeatedly to buy 'pre-turbo' on the old Mercedes??? if that makes them EMP vulnerable, could ya just easily take off the turbo? thanks! and also, my 93 1st gen cummins IS EMP proof even though it is Turbo....correct?
