I know it prolly isn't the most 'cost effective' swap. I was just stating an idea.. since he asked what motors you could swap in tere.

I was comparing a boosted Zetec vs. boosted SOHC.
I would rather boost a SOHC then swap to a Zetec than boost it, here are a few reason's: It would be cheaper. Your over all power output will be very simular. Like I said, the Zetec head flow's better, but just bump the boost up a psi or 2 on the SOHC and you've made up the difference. The SOHC has lower compression, makes things easyer for boosting, you can run more timing and less octane. The rings are set a little looser in the SOHC, bad for making N/A power but does better when things get hot. The short blocks in the SOHC are just as stong, in fact the main caps are smaller in the Zetec.
A zetec swap is'nt really needed to go fast. If some one wants a N/A motor only, then the Zetec would be the better way to go. But if it's gonna be turbo'd, might as well stick with the SOHC.
