2.0L head swap for a 2.3L Duratec
 
Hey. So, my 2.0L Duratec head (2005 Focus) is about to take a $h!t. Can I put a 2.3L head onto a 2.0L bottom end? Has anyone done this swap? Am I crazy or is this possible? Assuming this is okay, would I need a 2.3L harness/ECU? If I have to replace the head I figured I would try and get a little more bang for my buck.

Thanks in advance... be gentle [boxface]

Yes it can and has been done , I did this swap back in 2005 , it would be best to also swap the 2.3 intake and use the 2.3 cams

Sweet. Any idea as to where I could get a decent 2.3L head, cams and intake? And will the 2.3 bolt right on?

It will bolt right on , I would surface the head about .015 and add some cams , would be the perfect time , then add a tune

What would this do, exactly? And would this be possible on a 2nd gen?

This helps me out a lot. I have an 07 2.0L dtec and have been thinking about doing this head swap. Probably would be a good idea to replace your water pump while your at. If you do this let me know what kind of gains you get.

Absolutely. I plan to make the change here in a few weeks. Ill take pictures as I go and upload them when I can. As for a water pump, I am thinking about doing a complete rebuild since I will be replacing the head. Intake, cams, Water pump, rings, alternator, belts, plugs, and maybe even my coil packs.

More power. When you bolt a 2.3 head on a 2.0 block, you get instant improvement in flow through the head and can make more HP at higher RPM. Add a header, a decent intake manifold and some stage I or II cams and you can easily get about 180-190 WHP from the 2.0L engine, depending on your tune and type/octane of fuel used. [race]

PS: not sure about the 2nd gen thing... ask around. Someone has to know. In theory, you can.

The Dtec in my car is the same as the 07, so I think I would just need a tune.

I think theres some constraints on 2 g guys because of the throttle by wire and the cht sensor I'm not sure what years use it.
