Its not worth the money bro..
go for Daihatsu YRV ! its worth the money and there's a video in youtube (Nissan 370z vs Perodua kenari with a YRV engine)
guess what ? YRV wins and it may be as powerfull as a Lancer Evo if you know how to mod it !
Those engines are cheap- ask your foreman about this engine for more info..
theres a myvi somewhere in sarawak running with 4G93T...this would be cheaper.
but yeah.. for the FD2R K20A the halfcut is pretty expensive...havent included installation n custom fabrication yet. im pretty sure its possible if money is not an issue
but seriously... ur driving the WRONG CAR for this kinda things la... myvi seriously wasnt meant to be any form of performance machine.
