Please quit dreaming about the 1.6L version. That is never going to happen anymore.
Reason: Honda worldwide does NOT make anything other than a 1.8L and 2.0L engine for the new Civic (Actually the US hybrid one is 1.3L).
The older shape Civic was offered, worldwide, in engines ranging from 1.4-1.7. So Pakistan got 1.5 and 1.6 engines. They could, if they wanted to, bring the 1.7L engine offered in the US model to Pakistan. Back then, if Honda Atlas wanted to offer the Civic in a 500 hp V8 engine, they could not do so simply because Honda did not manufactur a V8 engine for the Civic---as simple as that!
If Honda does not make a 1.6 engine for the Civic, Pakistanis can't bring it here. Unless they are willing to do their own engineering and somehow figure out a way to fit the City engine in the Civic.
BTW, if you can visit all Honda sites worldwide and show me ANY country where a 1.6 version is offered, then there will, at least, be some hopes of an EXi in Pakistan.
