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 !

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!

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 the
motor 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

Welcome to
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.!
