Rightt bringing up an old topic. Earlya this year put some piper cams on my 1.8 zetec, along with a 2.0 turbo head, runs 100% perfect but as you can see, running low compression (didnt think of that at the time).

Anyways I want to make the most out my cams and see 2 options:
1- swap the 1.8 block for a 2.0 block, skim the head and make it high compression, then go the route of throttle bodies or something.
2- make the most from the low compression and turbo it, as the way i see it besides maybe some stronger valve springs, its capiable of a turbo now.
Needs some help on this from experts unlike myself

 

that compression wont be low enouph for anything above 6 psi with standard pistons in my opinion

 

I'm confused, what head is it? A standard 2.0 head will drop the compression very slightly on the 1.8 but not much.

Alot of people run decent power using standard pistons and ARP con rod bolts.

 

Agreed! The head won't really change the compression much...it will just be ported differently to a NA head.
