It isn't worth it anyway - you would need a new chassis, new shock towers, pretty much a new car. . .
An electric car only puts out a fraction of a horsepower while a Nitro car puts out close to one or even more. Plus a Nitro VIBRATES a TON more than an electric car does, so everything on a Nitro needs to be beefier than on an electric.
so, besides where to mount the motor, gas, etc. your electric car just isn't built to withstand the power and vibrations of the nitro.
