It would be a hideous job to change this engine out for for a different model....it would be much better to find a replacement 2.8l V6. There are plenty of older ones of these knocking about. It would be more economical to buy a replacement similar vehicle with a decent 2.8l V6 engine and making 1 good one out of 2 bad ones. It wouldn't be possible to change the engine out for a Ford 2.0l/2.3l or a VW 1.9tdi without changing almost every item under the bonnet....including Gearbox, Radiator, etc.
