Yeah, I have a 2.3L Focus. Just finished putting on my Cosworth race header and flex pipe along with the 2.5" exhaust.

The 2.3L came in every model in 2003 in CA, MA, NY. That list expanded to 5 green states in 2004. You could then option the 2.3L in any state bordering a green state in the base and premium cars. All power premium cars in 2004 got the 2.3L. So there you have it! Mine is a special order 2004 ZX3 with only A/C as an option and the 2.3L. Should have it on the dyno in the next week. Hoping to make about 170whp and 160+wtq with standard bolt ons.

Right now I have done the following:

Engine:
Cosworth Balance Shaft Delete
Cosworth Race Header
Cosworth Flex Pipe
Custom 2.5" Exhaust
FocusSport Intake
Cam Adjustment
FocusSport tuned SCT XCalibrator 2

Transmission:
3.82 final drive
Torsen

Suspension:
KW Sport Kit
Eibach 22mm Front Bar
SPC Camber Plates
Prothane lower motor mount insert

So I'd be pretty happy to see those numbers pop up with those mods.
