@Mirza967 and @rozzzzz I also want more powerful engine but my first priority is Petrol and CNG efficience.
I have a range of 1 lac in which i want all mechanical problems solved with all four disc brakes but i went to shershah and asked about the parts .... he said that it will take 1 week to come at his shop.
my friend told me that i should swap my engine with more efficient one, so that is why i thought of swapping it.
i am new in this stuff that is why i asked on pakwheels forum.
i know all wiring and other stuff that is why i asked someone to send me 1.0 efi daihatsu engine. i will also keep all these things in my mind when starting work on my car @Mirza967.
if there is any other suggestion for me, i would be very glad to know it.
