hi guys im building a zetec turbo lump, this will be my first engine build, ive done a few engine conversions, but ive never built an engine from the ground up, i had a rs focus lump in my car but it never ran right , so ive removed it and stripped it down,

since then ive sold the head and turbo, as i needed the money, but know im in a good postition to start building her up again.

ive heard the st170 head is one of the better ones to go for, is this correct , i m guessing i should do away with the vvt,

what management should i use, what inlet manifold ? what headwork should i do anything i should do to the bottom end ?

any help will be much appreicated (sp) cheers

btw the cars a focus
