If you were going to do a Duratec swap, I might try to convince you to do a high compression NA motor. With 12:1 pistons in a 2.5, a healthy set of cams, a good header and ITBs it would put 230-250hp to the wheels and be a riot on the street. Especially with a modern gearbox behind it (there's an adapter to use the RX-8 6-speed box available now). Or we could do a medium-boost turbo motor. Either one would be a lot of fun on pump fuel. Being as it's a pre-OBD-II car, there would be no issue with running an aftermarket ECU and maintaining emissions legality.
