I'd like to answer this if I may:
Yes I do believe this engine is feasible in Pak. The engine has been developed with a little headroom in terms of suitability for various regions, i.e. hot/cold climates, like all turbo cars. This engine will be soon available in some regions with very poor fuel quality, comparable to Pak, they have thought about low quality fuel from the start for this engine, trust me. This isn't a top of the line sports car where they develop it for use only on high octane euro/us fuel. These days modern engine ecu's manage fuel quality in real time and are able to adjust around the fuel used.
Let me tell you the biggest difference that I think will make a huge difference in Pak, fuel economy; I can't give you exact figures right now but I can tell you it will be a lot better on fuel than the 1.8L 140hp engine when driven normally.
Maintenance wise honestly it isn't going to be any worse than the current civic. Internationally this engine is long life service approved meaning service every 2 years if yearly mileage isn't high.
Other factors to consider; the 1.5 turbo will be a very different character to the 1.8. Some prefer one or the other so keep that in mind. 1.8 you really need to rev to get it going and this turbo you will have a wave of torque from very low down (1500rpm). Put it this way, the turbo will make full torque and hp a lot sooner than the 1.8, making it much faster in real world performance than the 33hp difference would make you believe. 0-100 time of 7.0.
Also remember if you want to maybe in the future add more power without breaking the bank that is possible with the turbo but not really possible on the 1.8.
