Question about 1984 Mercedes-Benz Mercedes Benz 300 Class
These days, everyone has heard about the amazing power that can be found from tweaking a diesel or adding extra components. I have a 1984 300CD and am very skilled at mechanical fixes and troubleshooting, but I still can't find any info on how to get more power out of my little turbo charged 5 cylinder diesel engine. Anyone ever try to ''trick'' their mini diesel engine?
You turn up your ADLA,but you wont have any overboost protection,some guys remove this,or you can just clean it out,this gives the boost to the turbo.

Those old engines were made to last - compare the weight of the motor to one of similar capacity nowadays; the old ones were made of cast iron which is quite heavy, the newer ones like the C270CDi Mercedes motor weighs about 30-40%less due to aluminium parts. Longevity suffers, but you need less power to drive the engine, giving you more power to drive the car. Furthermore, the common rail injection used nowadays are a lot more flexible and powerful, due to the fact that the exact amount of diesel needed per cylinder stroke is injected, whereas the old system injected a fixed amount per stroke, whether you are doing 20mph or 80mph. So, it overfuels at low revs and underfuels at higher revs. To prevent it from burning too lean the engine has a rev limit, roughly where the mixture is running at "100%" effectivity. The newer motors use computers to make the decisions based on 83452 different inputs, the older ones just measured the diesel needed and the air supplied.
So, the sad news is that the only way to get the car to perform a lot better is to put in a new moter eg. C270CDi, or put in a REAL motor like a 350Chevy :-D but leave the 300D badge on and see the other guys $h@ their pants when this "diesel" smokes them!
