90' B2200 Renesis 13b Swap
 

Hey guys, I recently picked up a 1990 Mazda B2200 pickup. I have an engine and tranny from a 2005 RX-8. I have seen people swap the FC RX-7 engines into them but I can't find anything on the Renesis. Is this doable with the stock ecu? How much different would it be from an FC 13b? Any information would be greatly appreciated!
