Are there any turbo-charged OM604? - Steve202 - 05-15-2021
Hello,
I am thinking about turboing an OM604. So I am looking for informations about it.
Which header could I use? Is it possible, to take a header from an OM611 or OM646? And could I use the intake-manifold from one of these engines?
How many hp will the conrods endure? Should I better use conrods from OM611/OM646? My power-goal is 250-300 hp.
The head gasket has to be custom made?
Please excuse, that my English is not that good. But I am from Germany, so English is not my natural language.

604, turbo... yes... although the internals may need some atention.
Well... besides the colectors a lot of things need atention:
1-IP , most probably block may need some machining to fit a M Pump as it is the best solution for lots of fuel, a VE can also be used but in this case, moding is needed as the original pump is the Lucas EPIC EDC, and this one worth nothing.
2-Head assy, need stage 2 mods or 3.
3- HG will hold, for sure if is MLS.
4-Pistons also hold, rings are same for any 89mm MB piston.
5- Rods very week ... CDI rods are a good swap.
6- Oil pump and squirters need some atention.
Basically is it ... certainly with 160cc of fuel and a lot of air it can be taken to the 80hp cylinder mark.
I can help u with it, email me at frgman@gmail.com if u wish.
