yeah well at mo have a 1.8 zetec lump and a wrecked mk4 fiesta shell. the plan was to build up a zetec turbo but after looking at the cash involved its all a bit much. I'm looking for around 230bhp so think a cheap zvh would be more up to the job and in my budget range. I don't know much about the cvh's apart from there's efi turbo and mfi turbo, i know the mfi blocks are hard work because there aren't many sensors on them. I was thinking an efi head would be the easiest to work with
