currently got a FRST EFI 1800 zvh in my fiesta.
engine is a bit tired and smokey

I have a 1800 16v doing nothing from my old car (fiesta)

how hard and what needs to be done to do the swap?

im thinking spacerplate (not sure £??) - or copper gasket maybe reasonable alternative dependant on price.
focus RS plugs (these fit and be ok? what spec are they?)
modified FRST fuel rail to EFI inlet (not sure how hard this is?)
ERST T3 and manifold (how hard to fit to zetec?)

and then breather system etc? no idea what needs to be done there?
also flywheel with turbo clutch?

what else have we?
