Found an 105 Bhp zetec engine..could be fun too..may-b putting a turbo on it... i'm still thinkin' with me brains

Could you guys tell me what i exactly have to change to make it a turbo'ed engine?

first swap to an 130 bhp spec engine then decompression pistons, cvh exhaust manifold and some nice big bore exhoust behind it? Can i use a cvh exhaust pipe or do i need something bigger?

Need some help guys can't make up my mind
