They won't drop right in because the motor mounts don't line up, but there's no reason you can't make the stock motor naturally aspirated.

ok just curious about this, in a piston engine you have to drop the compression ratio in the cylinders right to cope with the compressed air? Which obviously requires changing the pistons and fitting new ones. I dont know if its the same with a rotary but, would you have to change the rotor when your running an NA tuned 13b?

its not the motor mounts per say but the location of the motor mounts.

There is nothing internally which is required to be changed for going NA. There are things you can do internally for more/better power when going NA.
Since the 13B-REW comes stock with twin turbos, there's an exhaust manifold which connects the turbos to the engine. With removing the turbos, you will replace the exhaust manifold with headers (either custom or possibly from an FC).
