om603 Performance

[dfac69]

I just purchased a 1987 mercedes 300td wagon with an om603. When I got it, the trap oxidizer had already been removed. The car topped out at 65mph when I first got it. It shifted very hard and the oil was like gum. After changing the oil, fuel filter, transmission fluid/filter and removing alda, I can now hit 100mph pretty easliy. I just changed the very dirty air filter to a fresh k & n 9" cone. I noticed no difference and it was a pain, I do not recommend. Anyways, I would like to ask a couple of questions, as I am new to diesels, mercedes, and this forum. How do I know what injectors are interchangeable? I want bigger injectors but I dont know what will fit. I plan on this being a 500hp or so build (eventually). I also need to know how to "turn up" my injection pump. Also, my injectors seem to be leaking. My friend said its injector cups which I would like to change as well. I plan on a hx35 turbo and a better injection pump shortly, but I want to start with these upgrades, since the injectors are leaking anyway. Part numbers or links to the parts would be greatly appreciated. Once again, injectors, injector cups, turning up ip, and if possible a link to the injector return lines. Those leak too. Thanks so much!
