206 1.6Xsi Interchangeable?

[Mattr5uk 20 5 Cars]

I seem to be accumulating cars ATM apart from the 5 205s I've got a 206 1.6 16v 2001 I'm sure someone on here knows what fits from this onto the 205s. The rear callipers if I'm correct are same as the 1.9? Any ideas on what else? And opinions if its worth using the lump etc in a 205 or if its worth the time hassle and money to do?? Your opinions and advice are gladly welcome and appreciated
