Several post in the Mazda section have mentioned the first gen RX-7 could possibly be moving from ITA to ITB.
The reason (of course) is were too slow to be competitive in ITA. How about, instead of moving 'us' to 'B', give us the same rules as the piston enginge cars in IT and allow port matching on the 12A rotary?
