Performance Mods
Just a curious kind of mind thing. I belong to other forums where performance is the objective and also have seen some pretty extensive performance modifications to diesels. Light duty pickup trucks like my Dodge are famous targets.
I was wondering if anyone who frequents this forum has Modded their Mercedes Diesel, OM 617 and 603's in particular? Mild turn ups? How do you turn a 603 up? Is it much like a cummins where you first open air passages up for better breathing(ie. exhaust and intake tubing) ? ? route air up front to an intercooler? Turn up the injection pump? Any documents or websites out there on this kind of stuff? Just interested. Thanks a bunch.

Your 603 can easily be modified with ALDA adjustment and wastegate adjustment for more fuel & 15psi boost from I believe 10.5 stock, to go above that you can start to adjust the rack and add a bigger turbo, add an intercooler, it's all on here somewhere.
There's a smokey-donut video around here somewhere of a couple of cars (W124 and W201) that a Dutch firm tuned pretty extremely. - Jeff

Do a search, it can be done but requires a lot of time ,money, and knowledge. The Finns are able to get 400hp+ out of 603's. The stock IP limits you to about 180ish if my memory serves me.
If you instal an EGT guage you can turn boost, and fuel up a little bit, as well as play with the ALDA. Next step is an intercooler to get any noticeable gains.

Stock IP limits you, it's only good to < 200hp.

I think you're asking a similar question to what I was looking for on my tuning thread. Didnt get as many responses as I'd liked...
