If the engine is coming from the same model as yours you shouldn't have to change the loom over, all you'll essentially need is the engine and ECU . All the wiring for the sensors should be the same and the existing fuel pump should easily run the 1.6.

You might need the chipped key to match the ECU for the immobiliser though?? Depends on the set up, some are wired into the ECU , some aren't and I couldn't be certain about that Clio.

Understeer is when you hit the wall with the front of the car.
Oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall.
Torque is how far you take the wall with you.

Hi,if you are putting in a 1.6 instead of a 1.4 and the engine looks the same I would just swap over the engine only and check how it runs, your existing engine is a K7J and the engine you are putting in is probably a K7M, if you swap over the engine ecu you will need the immobiliser control unit and the original key.
