  2. MK1 Focus
    I have a 2003 Ford Focus SE 2.3L Wagon with 136k miles that shudders/struggles to start up when cold. Any ideas for what to look for? I have 4 new spark plugs New starter New valve gasket cover New fuel filter When I put the dash into test mode, fuel pressure was reading around 40 PSI so I...
  3. DURATEC Performance (2003-2007)
    Hey everyone, I’m new around here. Just bought a zx4 ST with the intentions of modding it, any thoughts on good first mods? I’ve heard that the suspension on 06+ models of the old ST’s are pretty soft.
  4. DURATEC Parts (2003-2011)
    I have some parts I want to get rid of from my 2.3 to 2.5 swap. I'm located in Southeast Florida for anybody who wants to pickup.

  7. Engine & Transmission Swap
    I found a place around where I live that has a 04 SVT engine that doesnt have the water pump for $1000. Think it would be worth it to swap that with my 2.0 SPI? I know that I would have to get a new tranny too so I'm also looking into that.
  8. ZETEC Performance (2000-2004)
    I am confused. I have a 2003 Ford Focus ZX3. I know for a fact that it's a Zetec, because of the VIN number, however it's a 2.3L. Is this possible? I only seem to be able to find things regarding to a 2.0L Zetec. I know I have the PZEV motor, too, which I hate!! I want to rip off the PZEV intake...
