mine is a zvh - yep it has took alot of work - and shit loads of money

but its not just the engine that is the probs

i destroyed my standard box after about 300 miles of it being on full boost (14psi) and the box had only covered about 10k previous. also u wil need a paddle clutch of sum sort.

i agree wit the comments that the zvh is very smooth through the range.

being honest if i regret anything its the fact i didnt go for a complete zetec version with the 16v head.

also if u go for a zetec or zvh u gotta go for a bigger turbo in my opinion - so i went for a t34
