I think this is what he meant.

"Hi I have a 2000 zx3 manual it runs good, but I really don't like the max rpm limit. I have a zx2 and the rpm limit is higher than the zx3, can I swamp the heads of the zx2 to my zx3? Is it possible to do? All the specs show it can be done. I want to know if someone has done it and how did it come out? What mods have to be done to make it work and does the ecu need to be tuned?"

Also, Welcome to Focus Fanatics!!!

Yes you can swap the heads but the ZX3 head is just as good , your zx3 should go to 6250 just like the zx2 does

For better performance add a SVT header , intake , TB and a tune and you will see about a 20% gain in performance

uhhh zx2 goes to around 7k... definatly not 6250?

but regardless if it revs more or not, you will need to get a vct delete if you want to use a zx2 head, and the vct deletes for the zx2 are hard to find... unless you can figure a way to wire in the use of the vct into your engine.

the vct is variable cam timing and it's on the exhaust cam (unlike the intake cam on the svt engines).

I don't think you're understanding.

HP peak (stock) is around 6,250rpm for both engines.
We know full well how VCT works and what the differences are between the ZX2 and the SVT ... unfortunately the standard Focus zetec does not have VCT, so both cases are irrelevant.
