From what I've heard, the intake ports on the SVT are bigger and the bolts for the intake manifold are a little off. The Focus guys have to file out the holes on a SVT manifold to make it fit on a regular Zetec. These sound relatively minor. I'll know more when the supercharger gets delivered. (the pic above is from the sale on the focus forums)
If I have to port my head to make it work, no biggie. I'm already prepared for having to do some weird crap with the accessory drive. The Focus has a two-bolt style mount for the alternator and I think it's smaller. I also don't know if the idler bracket that they supply is going to work at all.
Oh yeah, the SVT Focus also doesn't have EGR. I think that why the normal Focus guys also stay away from it. That and the Powerworks supercharger is MUCH better. Intercooled M62.
It's going to be a fun weekend digging into all of this stuff.
...that's if it shows on Friday...crosses fingers...
