Morning all! Firstly I'm from the not so Great Britain picked up a w210 over the weekend to swap the 606 into my w124 and ditch the old 603 non turbo anchor. Fly wheel and clutch I'm going to use single mass conversion from a mercedes sprinter van and maybe the same gearbox. I know I need to swap to a 603 sump and pick up? Which I might need some help with from you boys as we never got a turbo 603 here in England. My other question is, I know I'll be wanting bigger internals in the injector pump but, can my non turbo pump be fitted with an Alda then updated with bigger internals and used on my motor? If not then I'm gonna be in the market for a 603 turbo pump. Hope that all makes sense. Might be asking the same old stuff but certain stuff is hard to come by here, info and parts!

I gather the question is can an N/A pump be turned into a turbo pump. I think the answer is no, but I would ask whoever you intended on having modify the pump. They would be the ones to do it and they would know for sure.

I'll have to check when I'm back home from working away. Few diesel place locally. Would be ideal if it could but as you said I don't think it can be. Unless buying new om603 turbo pumps are near impossible to find without looking abroad

The last two 603 turbo pumps I sold went to the UK!

I also sold a guy in the UK a ton of Alda's, he was trying to convert N/A pumps to turbo, no idea if he was successful, I will try to find his info.

Thanks mate that'd be great. I've replied to a couple sales threads on here about pumps

You can make an external ALDA using a 7 psi wastegate actuator attached to the stop lever.It should pull the stop lever partially with no boost but also the stop lever must be able to travel more to shut off the engine.Take a look at this video it should clear things up
Dieselmeken shows outside adjustable ALDA for Mercedes Superpumps - YouTube
Or you could buy one already made by dieselmeken.Priced about 120 eur i think.

The difference between a turbo and non-turbo 603 IP is the ALDA (for turbo) and the elements size (bigger in turbo). So yes.
