Basically, throw out all the stuff to do with the engine and then install whatever motor you can afford with a charger and some batteries that fall within your budget. Vague I know but that's sort of where it starts.
You would need to work out if you want to keep the clutch or not and what motor and batteries you need and can afford.
You could do a lot worse then having a look at this thread of a Willys Jeep conversion.
After you've looked at it you may then have some specific questions formulated that would be easier to answer.
Looks like your evmath doesn't add up in regards to the controller and batteries. Even if you like the sum total for $, the amps, volts, watts and watt-hours have to make sense. And I don't follow you on the need for 4 chargers. Better recalculate some things
Not sure about the batteries. I don't think 144v and 12Ah will get you very far. Even the other way round 12v and 144Ah doesn't look any better.
I think maybe you should be looking at 12v cells with 60Ah or more per cell.
Assuming your Suzuki weighs 1400kg (and assuming lots of other things)
At 30mph you will require 7854W of power to push it along a flat level asphalt road on easy rolling tyres.
That gives you 262 Wh/mile
Your batteries have 1728Wh capacity and only 1382Wh at 80%DoD
That gives you a range of 5 miles at 80%DoD or 7 miles if you completely flatten your batteries.
If you used 12 x 60Ah batteries at 12 volts each you will have 6912Wh capacity at 80%DoD and a range of 26 miles.
Oh ok. What kind of power output does that motor have?
I'm looking to do a conversion using the drive train out of a Samurai (between 86-89) and I'm trying to find out what it will take to power it. I'm not using it to commute though. Just for trail riding and playing around offroad. Curb weight on the Samurais in the years I'm looking at are around 2,100lbs with a 4 cylinder motor. I don't plan on using anything but axles, drive shafts and the transfer case though. The rest I'll build on my own.
