Remember that porting requires an engine rebuild. Not worth it to pull apart a prefectly good engine unless you are very bored, have a lot of time, or about $2000 burning a hole in your wallet.

It requires engine disassembly and reassembly. This requires the typical cleaning, measuring and gasket replacement procedures in a rebuild. In theory you don't have to replace all the seals but that's just plain stupid unless you are tearing down a super low mileage engine. Hence, it requires a rebuild.

on an automatic. I would think that some gears would be a huge performance increase if you have no dont mind some slightly worst gas mileage. youll be just like a normal rx-7!
grab some 4.1's from a normal 5sp n/a or 4.3 from a miata or GTUs
stock in an auto is 3.9

Now the runners on the other hand, I have read mixed reviews. Comparing a Streetport to the option you suggest on an N/A, where would the most gain be realized?

Street ports rule. Best bang for buck for the NA rotary, hands down. Of course this assumes the motor is already apart, which it will be if you own the car for a while.
