What is the difference between the Skoda Rapid 90PS and 86PS version?

What is the difference between the Skoda Rapid 1.2 TSI 90PS and 86PS version? Is the latest the same engine as used in the current Octavia? Is there anything to watch for, such as the timing belt/chain intervals?
The 1.2 is being phased out in favour of the new 3-cylinder 1.0 litre engine. Skoda was late to switch from potentially unreliable chain cam 1.2 TSI to more reliable belt cam 1.2TSI. The 90PS will be the belt cam version, so needs a belt every 4 years or so, plus tensioner, waterpump and aux belt.
