phil its more the other way round.

I suspect the rings are gone in the zvh and that the engine needs a rebuild.

i have what was a good working order 1800 16v thats now doing nothing... so thought... hey what the hell it cant be THAT hard or expensive to do.

the important thing here is cost.... not anything else... needs to be very cost effective and effectively use up parts I already have.

i.e. I could use the zvh sump as it is already modded for the oil return etc.

cam timing? on the zetec you dont need adjustable pulleys do you? so would it be worthwhile tweaking the timing a bit (they are currently 105 cams)

what boost would i need to run to get somewhere like 210bhp? is it poss?

oh CR aswell.... what will i need spacer wise? 81 bore isnt it? but whats current gasket thickness compressed?
