The two engines are very similar; it's basically a small increase of 200 L. You should be able to retain the existing sensors. The intake/exhaust manifolds may have to be replaced due to possible increase in port size; if there is an appreciable difference, then that's not good; it can screw up the tuning. however I'm not sure on that.

You will have to perform the throttle valve re-learn procedures. If the car doesn't run right, you may have to re-flash the ECU.
