I thought the SVT focus just came with a nitrous bottle that was disconnected, and a warranty that would be void the instant you connected your factory supplied nitrous? Maybe that was a different model. But yes, they were all fwd, however there exists a kit to BOLT in a 302, diff and all, with no cutting or welding to be done (so I hear). There was that one supercharged cobra powered focus that cost upwards of $100k to make, and was faster with 5 people than with 1 just because the power to weight was so rediculous it couldn't hook up, but I don't think it was anything more or less than an extremely well made one-off custom.
Mikelly: I'd do a track day in a heartbeat too, but since the closest track to me is Sebring (home of the 12 hours of Sebring) and not really that close, I haven't had a chance to do one yet. Plus i've heard it's like a few hundred bucks, which I can't really afford right now.
