But to answer your question, NO! There will be no 1.5/1.6L Civic in Pakistan. They may have an EXi, but it will still have the 1.8L engine. Here is why:
Basically, you have to see if the manufacturer makes a particular car for SOME other country other than yours. If they don't offer the car anywhere else, you can never get one in Pakistan.
For example, look at Corolla Altis. Long before Pakistan had 1.8 Altis, the US market Corolla was 1.8. It was easy for Toyota to simply take their 1.8L engine and start offering it in Pakistan (not exactly becuase the American 1.8 produces 180hp whereas the Pakistan 1.8 produces 150hp!)
So Look at all the Honda sites around the world. Civic is not offered in a smaller engine ANYWHERE else. So bottom line---Sorry you can't get your 1.5 EXi Civic back! Rather, you must buy the 1.5 VTEC Crap that call City these days.
BTW, the EXi offered in the UAE market is STILL 1.8!!!
