hi guys

not to sure if this has been posted about before,

i have the 2.1 cvh engine ( zetec bottom end, standard rs turbo head)
would i be able to get more power out of the engine if i put on a zetec head so it would be a full zetec engine? or an st170 head?

any help apprieciated
cheers

 

you've posted in wrong section you need to re do thread in the car specific area under escort rs turbo and the answer is yes you want a blacktop head then you need to uprate the valve springs and that is it, but your bottom end might not be suitable now as your oil galleries might be blocked so not a straight swap and your compression may be to low also

 

oh ok sorrry and cvheers for the info mate
