yes I think you could do a converion for that price according to the research I have done so far. I have not done the conversion yet to my car, but it looks like it is feasible.

Here are some prices I have found

$240 - 911 crossed drilled rotors (set of 4 new)
$300-$600 4 piston 944 turbo cailpers (set of 4 used)

So as long as you dont go overboard, you could probably do it for less then a thousand. Especially if you can fabribate your caliper adapters.
