Hello, as the title says I want to swap my boring 69 hrsprs 1.3 rocam engine that comes in my 04 fiesta with the 1.6 rocam from a sportka/streetka wich makes a whaping 95 hrsprs, and i need some advice regarding the folowing.
I know that :

• they are the sane engine, just diffrent bore size
• one uses a diffrent type of injectors and I might think fuel pump
• bothe use iac valve and a DBW throtthe body

Now, my questions would be:

1. Can I just swap the engines without changing to the 1.6 ecu ?
2. If i swap the ecu, wich looks the same as my ecu, will i retain all the functions that my car had before ?
3. Can i use the gearbox from the 1.6 ?
4. If i use the gearbox what axles do i need ?

Thank you in advance guys for the answers and the help.
