Good find guys...K20 in a Civic which is stock. Havent seen this setup before personally.
K20 swaps are expensive and it would be great to see if someone has done it in Pakistan. A K series engine will fit in almost any Civic from 92 onwards (88-91 EFs maybe) but you will need new transmission or mod the existing one, new enigne mounts, updgraded suspension and braking components.

Of all the modifications you have mentioned about your car, i cant imagine how have you increased your performance significantly. I am not saying you are lying but adding an intake, header, exhaust, upgraded ground wires, tuning will result in nominal gains (on a 1.6 SOHC Civic no more than 7-10 bhp maybe) so i dont know what are you talking about?
Based on my experience working on D and B series Honda Engines...there is no magic bullet out there. Unless you go forced induction, all these mods bring about minor changes. Can you explain further??
