Loss of power on my Avensis

[Devontony]

Hi guys 

I have a 2008 Toyota Avensis that has lost power. I am convinced its something to do with the turbo. Before I lost power every time I changed gear it sounded like an Owl, no joking honestly. I don't know how to identify what engine I have too? I put in my reg number on auto data and it comes up with a cambelt kit and a timing chain kit, now I know it doesn't have both. 

Please can you give me some advice please?
