Kei trucks are very versatile vehicles, but their stock powerplant can leave a bit to be desired. If you need more power, why not try an electric conversion?
[Ron “Mr. G” Grosinger] is a high school auto shop and welding teacher who worked with his students to replace the 40 hp gas motor in this Daihatsu Hijet with the 127 hp of a Hyper 9 electric motor. The motor sits in the original engine bay under the cab and is mated to the stock transmission with a custom adapter plate made from plate steel for less than $150. We really appreciate how they left all the electronics exposed to see what makes the conversion tick.
The faux battery was made by a foam sculptor friend out of urethane foam shaped with a carving knife and then painted. It slides on a set of unistrut trolleys and reveals the 5 salvaged Tesla battery modules that power the vehicle. The fold down sides of the truck bed allow easy access to anything not already exposed if any tweaking is necessary.
We’ve seen a kei truck become a camper as well or an ebike powered with actual power tool batteries. If you’re thinking of your own electric conversion, which battery is best?
