How do I get another 20-30hp from my 87 190D NA - PeachParts Mercedes-Benz Forum

I like the car but it is just too slow. If I could get a reasonable power increase for a reasonable amount of money I could live with the car for quite a while. bearing in mind that there is no turbo. I have thought of trying to locate a complete 2.5 turbo setup with IP and all but so far have found nothing. Anyone have any direct knowledge of where one can be found. Short of that what other steps can be taken to get some more oomph. Can the IP be tweaked significantly or the injectors. I get absolutely no black smoke now at all, ever. This leads me to conclude that there is at least some power to be had by changing the settings of the IP. Am I wasting my time looking or are there sources I could get some info from. Enlighten me. Cheers Dan

Sell it and buy a car with 20-30 more HP. There is nothing you can to without a turbo to get that much power.

Propane.

I don't think propane will do him any good since there's not a turbo to provide air to balance out the extra fuel. As far as I know, NA diesels don't have much power potential beyond increasing displacement.

By far the least costly and least labor intensive approach is to sell it and buy a different car. Adding 30HP to that engine will likely cost more than the car is worth.

Would an OM603 fit in the engine bay? I bet you could find turbo 603 engines far easier than 602s...

That would be sweet! I think it would be a very tight fit, but I think it might work. I'm pretty sure I've seen some 190s in Finland that have either a 603 or 606..of course, they can do just about anything over there, it seems.

you can put anything in anything if you have money,

It is such an elegant little car that it is a shame to mess with it much. I have decided to sell it. Hopefully someone else can appreciate it for what it is. In the meantime I did a bit of adjusting of the ADA and a couple of other things which gave it a bit more zip not much but some. Cheers Dan

I even tried Methanol in my water injection in my 190D, and no, nada, none at all, zero increase in power. I think you are correct about propane injection as well, it does not work with NA Diesels.
