Firstly afzal, as your car is auto so converting it into manual will be an issue as you wont find manual tr of 1sz that easy.
Second part is of turbo.
Combining both, cost will raise to minimum 70k.
What i recomend you is swap in 1.8 vvti altis engine with some nominal alteration. Its an awsome project which i too have planned to do one day.
Anyways, a friend's friend have done a 1.8 non vvti swap in vitz and is running good. May be wasay ahmed will guide you further on swapping 1.8 in your vitz.
Later engine bay of vitz is big enough and you can put a turbo in it as well.
