    Default Reliability & Service - Duratec Vs. Zetec

    I realize that the Duratec is still a relatively new motor, but any thoughts on it vs. the Zetec strictly from a reliability and service level standpoint? I'm buying a sedan for my sister, so I'm trying to ignore the performance aspect, difficult as that is for me. Any early teething issues on the 2003's with the Duratec? I'm gravitating towards a 2003 SE at this point, and since I'm in NY, they aren't as scarce with the 2.3L as elsewhere in the country.

    Any input appreciated...

    Howdy and Welcome to [FJ]focaljet.

    The Duratec is being built in four countries on three continents. It's manufactured to the closest tolerances possible and precisely assembled by robot.

    It's Ford and Mazda's new 'world' engine and will see service in many models in 1.8, 2.0 and some 2.3 displacements.

    It has a predicted service life (under the care of the average person; poor fluid change maintenance) of 150,000 miles. As far as servicing this engine at the dealer, it's a plug-and-play. They'll just replace the entire engine while under whatever warranty one might have, if any problems are encountered. But I haven't heard of any yet.

    It is a well-designed piece, very light and quite reliable to 220 horsepower with the stock crank, rods and pistons, adccording to Mountune U.K. who builds motorsports versions for customers.

    Walter Marcy of Marcy Motorsports is a big advocate of this engine as well. A conversation with him will delight a performance enthusiast.

    As far as '05 model year availability, as far as I know, the 2.3 wil only be offered in the top level Focus ST Sedan.
    All other '05 models ahould be equipped with the 2.0 version Dutratec, which has a slighlty shorter deck height than the 2.3.
    Cyl heads are interchangeable, and all performance parts available for the 2.3 should work on the 2.0.

    I have an April '03 build 2.3 ZX3 with 26,000 on the clock and it has been virtually perfect, except for a noisy serpentine belt tensioner pully which was replaced under warranty at no charge at 6000 miles.

    The engine has incredible torque for a SULEV four cylinder; I'm quite pleased with it's day-to-day performance and I come from a 347 inch 302 V8 that had 420 lb/ft of torque.

    What type of problems? Auto or 5-speed? Isn't the Duratec spec tranny "beefier" than the Zetec one?

    Thanks for the feedback so far.

    July 03' w/ 42k on mine, no problems besides a slight leak in a power steering pump seal or gasket, fixed same day under warranty.

    side note: I drive it really hard. 75% of the time, the other 25% I'm either in traffic or at a stop light

    I've had electrical issues with mine (TPS, CAS, and Fan relay) but beyond that it's been pretty good. There's an "unfixable" creak from the front end (i think its a motor mount) but the dealer claims it's fine. My sychros dont work right near rev limit around 6500 or so...never have though I think I just need some better fluid in there and they'll be happier. They're just a little sluggish right now.

    I'm at 6,000 miles and no problems at all. (Yeah, I'm sure that's really helpful )

    I would point out that the MTX-75 on the Duratec is stronger than the Zetec version. However, it also has to deal with much more torque.

    Same with the automatic trans; in a PZEV sales brochure insert to the '03 Focus, Ford claims to have 'beefed' the auto for the considerable torque increase...

    The electronic shift map is awesome; where shift points are relative to revs and throttle position.

    Still wish I had a man trans, though.

    I don't know why, people marvel at the beefiness of my MAN trans.

    I forgot about that, I have that too. I guess I'm used to it now
