Hey. I scoured the engine mods forum, but i didn't see anything on this, so people who get upset at people who don't look before posting, know that there should be nothing but peace in your hearts toward this post. [/disclaimer]

So, i have a 2.0 SPI, but i'd rather have the 2.0 DOHC Zetec from the ZX2.

I've heard that, since the block is the same, you can just swap the head (valvetrain, and everything), intake manifold, throttle body, intake and computer.

I've also heard that the above is actually more work than swapping in the complete zx2 motor and computer.

if this was your decision to make, how would you do it?

Uhhhh how are you going to swap a DOHC on to a SOHC motor???? check erdt out or something... CuZ single over head cam will not fit a Dual over head cam or vise versa

I know that two cams will not fit a head designed for one cam. But what i'm talking about is the removal of not only the single cam i have now, but the whole head and valvetrain--everything above the block itself, and replacing that with the head/valvetrain from a DOHC motor.

know what i'm sayin'?

there are some japanese engines that people do this sort of thing with relatively frequently, or so i hear.

I gues the real question is; how swappable is the 2.0 zetec (Zx2 version)?

Is there some reason why 2nd gen people always pick the SPI over the Zetec?

In my mind, (which i'm the first to admit, isn't the real world) the engine bay of the zx2 is almost identical to the engine bay of every other 3rd gen escort, so, in theory, a Zetec swap for someone with an SPI would be fairly straightforward.

Hey Dude, If you are looking to buy a Zetec engine, I have one in my garage collecting dust. I bought it thinking I would try to put it in my 1st gen but that never happened (probably never will). Also have a ZX2 tranny as well. Let me know if you are interested.

I thought the Zetec didn't bolt up to the CVH/SPI trannies ?? *scratches head* At least I thought that was the reason.

This guy did it the oter way around.
CVH SOHC head on a Zetec block.
I've seen that before.. and I've still got the same question I did the first time.. WHY :?: It would think it would be so much easier to use off the shelf turbo Zetec parts (from europe) to go turbo..

Anybody got any information on how I could put pushrods on my CVH? Or maybe some info on a charcoal burning steam engine swap? Out with the New! That's my motto! [/sarcasm]

Yeah, beav', i'm not seeing any reason to put a CVH head on a Zetec. Seems pretty backward to me.

Pimp_scort_89_GT: I might be interested. I'm still trying to figure some things out. Namely:

Will a zx2 motor mount up using the 2.0 SPI's mounting points?

Will a zx2 motor bolt up to the lx's tranny?

Can i do a head/TB/computer swap instead of a full engine swap?

Am i retarded, or does the 2.0 Zetec have more tuning possibility than the 2.0 SPI?

When am i going to have to start paying back my college loans?

Mesa Arizona? Whoa. what would the shipping be on something like that?

Well, usually your college loans will not begin to factor in interest until you're no longer in school. I believe most loan policies allow at least 6 months after leaving school to begin billing you.. 2 of mine started after 6 months, and another one didn't start for a full year.

... yeah.. that's all I know to answer on this subject.

I'd be very interested in this info as well.

Yes a Zx2 Zetec will bolt to a third gen tranny, all mounts are the same on a Zx2 as they are in a third and second gen. The third gen tranny and clutch is stronger than a second gen, but you could swap it in a second gen with using a second gen flywheel.
No you cant just swap the head....unless you are the owner of a machine shop.
The reason of the guy that swapped a CVH SOHC on a zetec bottom end is because he wanted the displacement and strangth of a Zetec, but keep the engine managment the same, that and I heard the CVH head is stonger than the DOHC, not sure how true that is tho.
If you keep on loking in that guys wab sight there is a link to a guy who put a DOHC on a CVH block..I think
But remember the Zetec from a focus or contour/couger has a lot of differences with the Zx2, the Zx2 has a lot incommon with a thrid gen Escort.

So tranny mounts are the same for the Zetec as well? I mean, I can swap a Zetec engine and tranny into my 2nd gen LX without any welding or fabricating? 8O

Are the DOHC focus engines and trannies any different than the DOHC ZX2? The axles are different, right?

Yes a "Zx2" Zetec motor and tranny will bolt in to a second gen, you will need the axles, fuel pump and computer with all of the motor/fuel pump wiring.

Any other Zetec's and you will run into differances.

Casey (dimmwatt) at ERDT did the swap to his second gen wagon.

If I understand correctly, swapping a CVH head onto the Ztec block would make a much higher compression engine. Theoretically, the CVH head could be stronger since it has half the valves. You would have to compare the cross sections of the heads at their weakest point to be sure though. A lot of work for how much gain?

I nominate Jeffescort for "information man of the month"

I can see a ZX2 Zetec a good thing for an LX, but for the GT it would be almost point less for 3 hp and 11 lb ft.

Oh and I can't go to erdt...they banned me...for posting information...about cars. :roll:
