Mercedes OM606 Fuel Pump

I'm new to this entire Mercedes Diesel scene, and I am thinking about swapping one into my truck.

I have a 1990 Jeep Comanche, and originally had the idea of a stroker motor, however I ended up selling it off, and was wanting something else instead. Fast forward, I found out about the OM617, but I was not satisfied with its performance. So, I heard about an OM606, and the ability to swap it to a rear sump, and I knew I HAD to have it. The dimensions are very similar to the Jeep 4.0, and the weight and rev range as well. I just have a few questions that I couldn'd find online anywhere.

First of all, can I use the OM606 pump with a standalone ECU? I get why everone likes to be fully mechanical, however I would assume the ECU would be programmable(sort of like a "chip" in a diesel that lets you load separate tunes, I.E. tow tune, high HP tune, conservative tune, etc.) If that were the case, I'd love to get the electronic pump bored to a bigger size, so I could make more HP, and have it adjustably tuned by a switch.

My second question would be, why are there no rebuild kits for an OM606? I was planning on picking one up with higher miles for cheap, and I was going to possibly get it honed, if necessary, and bored if it's that bad, then re-ring, pistons if required, and get crank polished, but I cannot find many of these parts online.

Another reason I'd love to keep the electronic pump is I live in California, and I will be required to have all of the smog parts from the existing car(the E300D) installed on my Jeep, in order for it to get refereed and pass smog.

I apologize if these questions have been asked before, however I can't seem to find answers to these online. Thank you again for any tips and advice.

A chap does make ECUs for the EDC pumps. I don't like referring people to other places but honestly everything you want want to know is on the forum, including the ECU guy.

You can get larger elements installed in pumps if you want big power but it has to be done by a specialist shop. Most will recommend a Swedish company called Dieselmeken. There are some others around though as well.

Honestly your best option is just to pick up a lower mileage 'should' not need any work for a long time. It's a fair investment in parts and money to rebuild one....just start off with a good engine

All the rebuild parts are readily available. You can order them from Pelican or your local dealer. There is no prepackaged "kit", you just provide a list of part numbers and quantities.
