Hi! I've been browsing the forum for a couple of hours now, and I'm still not sure about the power ratings and equivalence between ICEs and DC motors.

I want to convert a classic 1981 Daihatsu Hijet Wide 55 microvan.

Land vehicle Vehicle Car Van Motor vehicle

the original engine's specs are as follows:

Type: four-stroke, water-cooled two-cylinder AB20
Displacement: 547 cc
Power: 22 kW at 5500 rpm
Torque: 4.2 kg⋅m (41 N⋅m; 30 lb⋅ft) at 4,000 rpm.
Transmission: 4 speed.
Max. speed: 105 km/h

I want to at least conserve the same power and speed ratings, and ideally make it a little better. I want to achieve an autonomy of 100 km.

I found this forklift motor for sale:

Product Water Cylinder Plastic Liquid

Type: Series-wound Brushed DC
Voltage: 48V
Amperage: 170A
Power: 6.5KW
RPM: "about 1500"

weight: 85 kg
length: 47 cm
diameter: 25 cm

So, the thing is that according to some posts, this should be ok, but The power rating seems too low. another thing I did was using the EV calculator, but the results seem to be off, as it says I would need a 50 KW motor to be able to achieve the specs I want.

I still can't seem to wrap my head around over-volting and brush-timing and such.

Any help would be deeply appreciated. Thanks a lot In advance!
