Mercedes S123 station wagon with Tesla SDU

Hi everyone,
my name is Stefan and I am living in the southern part of Germany.
Currently I am in an early planning phase of converting a Mercedes S123 station wagon (E-class built between 1977 and 1985). Have been lurking around this forum and DIYelectriccar for quite a while now, still more questions than answers...
I want to replace the whole original drive train and fit in a Tesla drive unit controlled by Openinverter. Regarding power I want to stay within the max range of the original ICE which was 185 hp / 136 kW. I hope to get a minimum range of 150 km.
Regarding batteries I read that these PluginHybrid batteries seem to be a good source. What Voltage am I looking for when planning a pack?
No clear idea about my requirements for charging yet, the more charging power the better? Still trying to get my head around this topic generally...
My workshop is still blocked with my current project, a 1986 BMW 635CSI. This will stay on combustion engine, have already invested too much in it... Hope to finish this car soon, but in the meantime I'd like to play around with my new project and possibly already buy some components and get the electric drivetrain running on a bench.
So I think I am looking for a small Tesla drive unit. This could be a model S/X rear SDU or should I wait for the Openinverter solution for Model 3?
Any benefits from Model 3 drive units over S/X?
Concerning the rest of the components, I am also still quite confused what to look for.
Any proposals for charger, DC/DC, HV distribution and other components?
I hoped to stay within 15.000 € for the components only (no labour costs). Does this seem realistic to you guys with more experience?
thanks a lot
Stefan
