Explain "Great Civic" How come on what standards?
2ndly make sure its all functional with wiring sensors as good or close to original OEM working. not jugarofied in any way else it would be PITA to actually fix it.
engine swap as you call is i guess an assembly changed(engine block head changed with another one from scrapyard with all same wiring as old) or its a complete change of wiring engine mounts???
