Now, whether the pair of ECU's comms with any 'Body related' ECU's as well, such as ABS, SRS, elect dashboard, etc, etc--Who knows!

I have heard of someone who fitted a Sprinter engine to a car (W201?) with all its ECU's etc, but cant 'break the Immobiliser'
--Maybe there's other issues with it too, I dunno...

Easiest way is drop the electronics and tune it mechanically, Thats what the Finns and others do....

Later Coomon-Rail Direct-Injection engines ain't as tuneable allegedly and you have all the issues above...
I was thinking the om603 in a w123 chassis, most likely a 300td (love those wagons with the yellow fogs). I was reading a bit over on superturbodiesel.com and found out that the biggest struggle with diesels is getting the inline pump to push out more fuel. Also saw that a common solution was to upgrade the elements. Once this was done then a bigger turbo (holset seems to be the most popular with the big HP Finns) could be installed or even adding a nice supercharger to the mix. Correct me if I am wrong in any of my thinking or have skipped a couple steps.

What kind of hp could I expect if I upgraded the elements to 7.5mm (guy on superturbodiesel.com does this and gets the parts from a guy in germany can't remember his name though right now) and also upgraded my turbo to say a big holset one (hx40?)?
