seriously just buy a 1.6 16v it'll be cheaper and way easier.. transfer your good stuff over to the new car and sell the old one to the scrappy.... the only engine swaps that are worth it are the 1.8t or r32. The rest is a waste of money and time.

I was exepcting that kind of replies. Do you think that your reply added some value to the thread ?

Agree with the above, at this point it's not worth doing the engine swap, unless the shell itself means a lot to you or if you just want the experience of doing a swap.

Either way, answers below:
1) Fuel pump will work fine. Check part numbers online for fuel pumps from a 1.4 and a 1.6 if you want to verify yourself.
2) Brakes will be fine, but the 1.6 16v has a bigger radiator than the 1.4.
3) None of the 1.6 16v engines used a cable throttle body, they are all drive by wire. The 1.6 8v, however, did use a cable throttle body. The engine codes are BFQ or AVU. In both cases, the 1.4 throttle body is smaller than the 1.6. I think the 1.4 throttle body was 10mm smaller in diameter.
4) I believe axles and gearbox are different on the 1.6 to the 1.4, and so is the cluster/clocks. The 1.6 rev counter has a higher red line than the 1.4. If you get an ECU kit from one car, then you won't need to code anything. The kit should include ECU, instrument cluster, keys, and lock barrels.

Thanks a lot for the information. It's my first car, and would like to keep it as long as possible. Furthermore it's a good platform to work on and gain some experience.

Minor update, mine is not a DBC, it's a DBW eventually. So i should have a lot more engine code options right ?

I was trying to avoid changing the instrument cluster, keys and lock barrels. Coding will be faster/easier/cheaper.
