Here is the info about the Duratech 20. I got it from Wikipedia and can't vouch 100% for the accuracy but I have no reason to discount it.
Beginning in 2004, Ford dropped the old 4-cylinder Zetec engines in favor of Mazda's MZR design. Thus, 2005 and present Duratec 4-cylinder engines are Mazdas. This includes the 2.0 L Duratec 20 the 2.3 L Duratec 23 and the all new 2.5 L Duratec 25. The engine is currently built by Ford in Chihuahua, Mexico; Dearborn, Michigan; Valencia, Spain; Laguna, Philippines; and Nanjing, China.
 Duratec 20
The 993 is a 2.0 L (122 CID; 1999 cc) version built in Chihuahua, Chihuahua, Mexico. Bore is 87.5 mm (3.44 in) and stroke is 83.1 mm (3.27 in).
It is used in the US/Argentinian Focus and the Brazilian Ford EcoSport. (European Fiesta ST, Ford Focus and Focus C-Max, Mondeo, S-Max, Transit and Galaxy use Duratec HE engines). On the 2007 Focus, output is 136 hp (101 kW) at 6000 rpm with 136 ft·lbf (184 N·m) of torque at 4250 rpm. The 2007 Focus sold in the US states of CA, NY, MA, VT and ME comes with the required PZEV emissions 20E version which produces 130 hp (97 kW) at 6000 rpm with 129 ft·lbf (175 N·m) of torque at 4000 rpm. The PZEV is available as an option in border states. The compression ratio for both versions is 10:1. On the 2008 Focus, output is 140 hp (100 kW) at 6000 rpm with 136 ft·lbf (184 N·m) of torque at 4250 rpm. The 2008 Focus sold in the US states of CA, NY, MA, VT and ME comes with the required PZEV emissions 20E version which produces 132 hp (98 kW) at 6000 rpm with 133 ft·lbf (180 N·m) of torque at 4250 rpm. The PZEV is available as an option in border states. The compression ratio for both versions is 10:1. It has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods, a one-piece cast crankshaft, and a cast aluminum or reinforced plastic intake manifold. It does not have variable valve timing. The power output is less than the Mazda version which does have VVT.
The plastic intake manifold on early versions has a major fault due to poor quality materials. The manifold has swirlplates mounted on a square shaft at the aperture where it mounts to the cylinder head. Early 4 cylinder Duratec engines can be ruined when the swirlplates break off and enter a cylinder . Most cases are of single swirlplates but also the shaft can wear and break. Early signs of this fault are evidenced by a ticking noise emanating from the front of the engine. This can occur as early as 25K miles, with failure typically occurring after about 90K miles.
