How are EV drivetrains salvaged from newer vehicles, and installed in a conversion? I imagine there are lots of parts that have to be removed, then installed the same way to make the drivetrain think it is still driving the original car. Otherwise the car computer may refuse to drive the motor or be in limp mode.

 Ok,
so I brought my Van through three engine conversions since its 2.1L 
days, it´s now
2.5 TDI Audi V6 incl reversed Tiptronic. sine 2006

The "keep it stock, genuine" Vanagon, : It´s long gone, so keep that in 
mind for text below!

Turns out, this latest iteration is slowly biting the dust:
Tiptronic is leaking ATF (heavily between trans/engine, probably 
converter/oil pump seal, if not both seized), converter clutch 
definitely busted.
Engine is missing at least one rocker arm under the camshaft (visible 
via Oil filler opening). Where is it? Who knows. How many more are 
missing? Who knows.
This summer, camping season is lost anyway, so I could try something 
new: electric drive.

Now:
I could get the whole drivetrain repaired. I estimate (roughly converted 
from Euro)
gearbox $3000
engine (incl Turbo and stuff): $3000-5000

Idea:
Throw the whole damn Diesel out, and get electrtic. The Van would be one 
of the first electrics in this decade.
Conversion prices may vary. I am in the E-vehicles business anyway, so I 
hope to get most of the conversion done myself.
I only need recommendations for which motor/inverter/controller might be 
best. Integration with Vanagon/AudiA6 is to consider.

What are youre opinions?
200+ horsepower, no need for 600+ Tesla.

Iterations before:
-2.8 12V Audi V6 1998
-2.8 30V Audi V6 2000
-2.5 TDI Audi V6 incl reversed Tiptronic. 2006
