[Biturbos4] I think I really did it this time (timing belt gone wrong) HELP!

Yeah, I have to concur with Igor, Matt.  That noise is a pretty 
unmistakable clanking.  I wouldn't reccomend messing with it for another 
instant and take it straight to a paid mechanic.  If you're religious, pray.

I had it slip off as I was removing the belt, and the passenger side cam sprocket and cam popped and went to the left.  I had marked it before on both, so I brought it back to that point and reattached my camlock thing. When I started the job, I rotated the crankshaft to the point where the holes in the cam sprocket flange were parallel to the ground. As I was putting it all back together, and checked my marks, and they were just a slight bit off, but both of them were, so I assumed that it may have turned a bit.  But the toothed belt would not let me change that at all.

But if I stab the throttle, I'm getting an awful clacking sound that sounds like it's coming from the middle of the engine somewhere.  I can't tell whether it's due to timing being slightly off, or what else it might be.
