There were at least 2 base engines for the first gen Focus. The 2.0L SOHC split port and the 2.0L DOHC Zetec. The Split port is rated for higher MPG from lower cam profile and taller gearing. ZX3 and ZTS had the Zetec standard. While the LX and SE came with Split port standard but Zetec was an option. Not only do the PZEV engines reduce HP, Torque, but also MPG.

There was a high output version of the Zetec available on SVTs. Then there was the 2.3L Duratec in the faux "ST" for MY '04-'05 and the new 2.0L Duratec base engine from MY'05 on.
