Zetec OR Duratec? I wish I had known the difference before I started. Which one should YOU buy?

[@astjeff80]

The st150 uses a fiesta gearbox it's not the original mk1-5 chassis but it's a 5 speed and smaller

[@andyswales781]

You'd be best with an ST170 engine a correct bolt pattern and there a built bottom end of stand

[@mike_themechanic]

I'd love a 170 engine but the last one I saw for sale in Sweden cost £1400 🫣😲

[@GarryRobinson-ru9tg]

No offence but your out of your depth a bit here, it’s a Ford engine mazda adapted. Mtx75 box fits, fiesta st150 ib5+ box fits, focus mk2 2.0 duratec box fits. Any box with a bell housing adapter plate for £2-300 quid A bit more homework would have saved you a lot of hassle. I’m no mechanic but know these things. Duratec 1.8 2.0 2.3 2.5 Ford engine 2.5 has vvt Mazda 1.8 2.0 2.3 have also got vvt. A lot of internal differences/ dipstick location inlets etc. Major thing you should have checked. Duratec has a chain Zetec has a belt Hope this helps a bit to someone

[@mulmanalmelo]

These duratec is also used in volvo v50 c30 2003-2012 front wheel drive with 5 speed MTX75.

[@mike_themechanic]

True.

[@madmatt2024]

In the US, every Duratec powered Focus with a manual transmission has the MTX75. They are pretty easy to find. The 5 and 6 speed transmissions from the Mazda 3 also bolt up.

Probably. Anything will fit it just needs more fabrication work to fit it.

Old Fords are like a LEGO set! Every engine will fit every gearbox and drive shaft. The Mk2 Mondeo in 1998 still has either Silver or Blacktop but all the bolt patterns are the same for RWD or FWD I built a ZVH turbo engine (1.8 zetec bottom end with CVH head) and all patterns are the same. When the Duratec came out they used Mazda engines and gearboxes. But when the Zetec SE came out (Yamaha engine) they used the old RWD T9 pattern!

[@Strider9655]

The Mazda version is arguably better than the Duratec, Ford cheaped out on the bottom end components, namely the pistons and rods, to get 300bhp from the Duratec takes a lot of work, not so much with the MZR.

Ib5 out of an st150, bolts straight together.

Any of the ib5 gearboxes bolt straight to the zetec engine

[@branney6914]

This is the confusion - the st150 is definitely duratec 2.0 and definitely ib5... I wonder if there are multiple variations of the duratec blocks with different bell housing bolts no one talks about...

[@madmatt2024]

@@branney6914 Highly unlikely. The transmission just has a different bell housing to fit the other engine. This is very common.

Can be souped up to 230hp on the standard cranks no problem. Great engine.

[@1crazypj]

Are the 'black top' engines cast aluminium or engineering plastic? Biggest problem I have with Ford is they use the same name for vastly different engines (guess that's the problem you found as well?) I've got a 2004 Mazda B2300 but no idea what actual engine is in it, I know it's Ford and maybe Ztec? If I was still in Britain it wouldn't be a problem as I knew several people working at the Bridgend Engine plant (but I think that's also been closed down now?)

[@mike_themechanic]

They are cast iron blocks with alu cylinder heads.

[@1crazypj]

@@mike_themechanic Sorry, I should have been more specific, I meant the cam covers

[@mike_themechanic]

The black tops are plastic and the silver tops are aluminium but the silver top does fit on the black top.

[@1crazypj]

@@mike_themechanic That's good to know, 'plastic' seems to distort and leak oil into spark plug recess. I've worked on motorcycles about 50 years and never liked engineered plastics on engines, even alloy on the Honda 750/900 (and various Kawasaki's, Yamaha's and Suzuki's) allowed leaks around plugs when the seals were not in right or age hardened.

Still have it. Inlet manifold is included. No wiring unfortunately

@@mike_themechanic Thanks for your answer. I am thinking about using the engine stock including injection and everything so I would need the loom, keyfob, instrument cluster. I suppose I should try to get a complete scrap car. What is your plan to get the fiesta through Swedish mot/besiktning? Keep up the good work.

[@mike_themechanic]

That was my plan from the beginning but it's alot more work than I was planning on. I've gone with an ecu from Motorsport electronics and a set of bike carbs so it's only 3 additional wires to the loom plug and play for the rest.

[@edalbagem]

@@mike_themechanic I just watched a KZbin video about the duratech and realized that my plan is not possible. The intake manifold is not going to work in a rwd escort and since its made from plastic its not possible to work on. I will have to rethink this. Getting scrap engines etc in the uk is much cheaper than in sweden as im sure you know but i could still use/modify the standard exhaust manifold. I suppose it could be possible to build an inlet as long as i use the thottlebody...

[@mike_themechanic]

There are people in the UK that build rwd escorts but I'm not sure which engine they use. I got my engine from a scrap yard in Sweden but it didn't come with everything so its took me time to find all the extra parts I need to fit it in. I would have liked an st170 but they are crazy priced in Sweden and its only the head that different to the engine I already have.
