I’ve had the idea of converting an MX5 to electric for a while and had been tossing this around with a few friends. Having recently bought an old MX5 I’m actually loathing the idea of taking out the beautiful petrol engine and I was dismayed to discover that other people have already attempted the conversion that I was considering! 
I guess I can attempt the project at at later stage. It all looks very expensive, I might look into it later when the cost of parts comes down.
