Looking for advice and any upgrades or mods to improve the reliability and preformance of a 2013 mk 3 1.0L ecoboom cheers 

Change the wet belt asap if it’s not been done already.

Booked in for Monday to have it changed at a ford dealership £1600 with full check over ect

Also to add are there any parts from later or more heavy duty models that can be put into the 1.0 ecoboom to make it a bit more robust I've been shafted by dodgy dealers and flimsy work that's caused problems so trying to eliminate all I can while fixing up a car I enjoy!

Well I've never seen that before! 

The words "Ecoboost 1.0" and "Robust" used in the same sentence 😂

Just make sure, once you get bill of health from current engine, that you change the oil EVERY year, at least, and use the correct oil and NEVER use flush

There were problems with coolant hoses on early Mk 3s and a recall. Should have been sorted by now, but worth a check.

Many threads on the subject, one example here:

The cooling system modification recommended by @JW1982 in the second post of that link would definitely improve the reliability.
