You need to tell us where you get your electronics from, because most people I am sure don't have access to a surplus store like the one you are blessed with.
cool link, lots of goodies there, I'll need that one for my build.

A lot of money first. A good light weight vehicle. 9" motor, Soliton1, Synkromotive controller, Warp Drive Controller, Zilla Controller. A large pack of lithium batteries. 45 kWH at least. A good charger and lots of money. Oh, and more money. It will be expensive. You won't be able to do that with Lead Acid batteries. PETE
Most of the other stuff is minor compared to the car, motor, controller and battery pack.
Okay small update, I'm getting a controller with torque control, DTC, with speed and torque modes. Freight company is supposed to be picking it up tomorrow. I will update again when I get it.
The contactors and other controls for the heater, brakes, and steering have all been put into proper electrical enclosures. I also got a vacuum pump to operate the HVAC dampers/air doors. Pictures soon
I am a little confused with something though, It seems I can't get full torque with DTC, I can only get full torque in scalar mode with "IR Compensation" which I assume is more or less equal to torque boost or voltage boost.
The torque control with DTC works great, it just doesn't provide full torque, which is important. Torque control is also important, I just can't seem to make both happen at the same time.
I'm not using any encoder now. Knowing that I may attempt to attach one. The drive came with (what I assume is) an encoder board. I've got an encoder as well. Now to get it onto the motor..
Okay, the van now has yet another motor, a 30 HP 6 pole motor, and things are looking pretty good.
The controller seems to be able to get up to 3 x nominal torque from the motor. The DTC is great, it drives just like the normal gas version in torque mode, and it can go into speed mode with the flip of a switch for Regenerative Braking.
The biggest issue now is the batteries... they just can't output enough current. Youtube kind of ruined the video, but you might be able to see where the bus voltage drops down to aronud 445 volts
Max power at this point seems to be something like 50 kW when the batteries are charged and heated.
Still, the van seems to be able to do 50 MPH on level roads pretty easy.
