A friend of mine swapped a b18c motor into his civic ex and he's quick as hell. The entire swap cost him over $4,000 though, but he said it was well worth it. The other thing is, you might wanna do some more research on the ECU. My friend who has an OBD-1 failed emmissions because you need an OBD-2. He's gonna try using his civic ecu now so we'll see how that goes.
