I am not a big fan of the rotary engine(however I did want to put a 13b in my spitfire) but that just doesnt seem like a very good swap IMO. That car will not handle nearly as well as it did before plus that could not have been cheap or easy to swap out and fabricate everything needed to make it fit and be reliable (I would assume adding a turbo or modding the rotary would be much cheaper and easier).
