We try to give helpful advice to all   
EV builders, and so far have not
charged for it, as many others now
This does take a lot of our time but
feel it is worth it for the EV future.

If you feel we gave you some         
valuable information and it was       
 worth something to you, please      
   make a donation so we can          
 continue helping others as we        
           have helped you.

       Thank you !

We are an electric vehicle conversion company that did our first electric
car conversion way back in 1975. Our goal is to create
quality electric
car conversions using
quality parts.  For the home builder we sell these
parts at reasonable prices too!

Build a car for you, not for them ! (the oil companies!)        
We take pride in our work and
try to build to the highest quality
front battery box of a miata
conversion, holding 5 batteries,
all wiring hidden from view
We strive to build to the highest
standards of quality and create a
vehicle that a novice EV'er can
confidently drive.
This is under the front battery
box, once again there is no bare
wiring. This is a Warp9
motor,mated to an automatic
transmission. This is wired to a
curtis controller
both of which we sell of course!
(and more!)
Here is another view of
themotor before wiring, with
power steering and air
conditioning mounted, and the
alternator for charging the 12v
system, only energized during
closed throttle.
A complete set of pictures
are now on the "projects"

conversions since 1975
At EV-propulsion llc we have been converting cars to full electric power since 1975.

We sell  quality electric car conversion parts with consulting services available. Or we will
convert a car for you using our years of experience to build you an electric that drives as
well as your gas car without the noise, pollution, or maintenance of a gas powered car.

Since our first conversion in 1975 after the first "oil crisis" we have continually improved our
design so that now you can have an electric car capable of highway speeds with an
automatic transmission, power steering and brakes, and even air conditioning. We take
tremendous pride in our work and our conversions have the look and drive feel of a factory
built vehicle.

With an electric car, you will have a zero emissions vehicle, be able to bypass gas stations
and "plug in" at home to "fill up", and also enjoy the silence of electric drive.

You will also have huge savings on maintenance, as an electric motor has only one moving
part compared to hundreds in a gasoline engine, there are no fluid changes, filters, and
tune-ups required, and all at the equivalent of 180 MPG.!
