As both of those cars are front-wheel drive cars, there would be MAJOR reconstruction needed to fit the 13b Rotary into it. It would not fit onto the transmission already in the car, even if it would I doubt the transmission is built enough to handle the load. You would need to use a transmission matched to the engine, which would mean converting the car to rear-wheel drive. Possible? Yes. Expensive and time-consuming? Most definitely. There ARE cars out there that have been converted from FWD to RWD (and even AWD), but the price tags associated with them are often worth much more than the gains and done 'just because'.
