Not that I've ever seen, but it shoudln't be too hard to do with a single throttle body adapted to fit the stock carb manifold. Or if you actually have two intake ports, one throttle body per cylinder, with a custom manifold. That would be pretty sweet! You could drive it with MegaSquirt, and maybe add a little boost to the stock motor!!! You might be able to get 50-60hp out of one of those little guys! Something like an Extrudabody throttle body would probably be the easiest to adapt.
I know there was a performance kit sold back in the day for these cars. High compression pistons, and a header and I think they were able to bump the car from 36 to 45hp. I guess it would outrun the Minis of the day. Not sure if they were talking the 850(?) minis or the 1275s. The 1275s were quick, so I think it would be a stretch.
Heard rumor of certain Goldwing pistons fitting in there too, other than that haven't heard or seen much else on modifying those motors.
