If I was to swap a 1.0 for a 160SR engine from a Micra K12, would everything be directly compatible? This includes the ECU and the engine setup with the gearbox and wiring loom. Also, the engine is advertised as not having a throttle body, so would this mean buying a new throttle body or re-using the current throttle body? Because the prices for a new throttle body are in the £700 range ....
