Expert Answer

The 1 SZ engines are fully interchangeable regardless of cabin type. All landing dimensions of the engine are standardized. However, if you install the engine from another car, it is better to replace it together with the native control unit. Since you will be installing a new control unit, you need to transfer the immobilizer from the same engine and the CHIP from the key to your car along with it. Thus, if you buy a used engine, ask the seller for a complete control unit, an immobilizer and a chip in the key. This would be the best option. After replacing the engine, it will work immediately without problems.
