honda is not suitable in khyber.
It's really hard to fit in a honda engine because of its dimensions and it requires serious mods in the engine bay.
try Toyota engine 2nzfe or get a G series engine installed with 15A or 16A. both Suzuki engines are like bolt-on fit in khyber with very little mods.
they produce ample power and are economical too.
let me know from which city you are so that can guide you more?
