i changed the bottom o rings of the injectors in order for them seat properly in the zetec rail the tops were fine. i have not changed the valve springs as i aint gonna be running major boost if they cause a problem then i'll change them. i only used the 2.0l tb and cams as they came in a doner engine that i bought off flea bay for sump, pick up pipe and ally stat housing etc etc.

if valve springs are that importatant who makes a decent set and what sort of cash are they???

thanks for advice

cheers,
Phil
