You need the Ford Mortrsports Apple Green 42`s or anything that will interchange with them

question #1 still hasnt been answered, how much PSI can a stock zx3 zetech engine handle safely and what to do to let it handle more PSI? thanks

I think the psi thing is hit or miss, some have higher than others.. Good luck though.. Hope you plan on upgrading later.. But sooner would be better.

None , NO boost is safe on the Zetec with out proper tuning

...with proper tuning what can a stock engine handle?

With proper tuning and 93 octane fuel 8psi in my opinion is max , If you are willing to run higher octane 100 to 110 that 250 is a good safe number and i have made over 300 at the wheels on an all stock Zetec

Makes me wonder:
On an SVT Zetec, with a little headwork (including a thicker head gasket), what kind of boost can you safely run?
