How far have you got with this azzy? Have you sourced a turbo yet? Do you know what boost to run? What about the exhaust, wastegate and induction piping? Have you looked into remapping yet? You'll probably need an Apexi Power FC or similar to take over engine management.
200 bhp from a 1.3 engine for less than £1500 is really not possible IMHO, even if you get a second hand turbo. You would really need to strengthen the block to cope with the extra power and this would soak up most of your budget.
