I siezed p the engine on my CRX and am wondering if the swap of a Civic Dx engine I have laying arund will swap easily? I've got it in storage. I'm not sure if I have the transmission. I guess I would need the ECU and wiring harness from a civic, but other thank that. what would I need to replace?

Thanks

just reuse your Rex intake & exhaust and trans as the motors are identical except the Dx in 1.5l and the Si is 1.6L .
