**** you're almost to a used FAST for that much.
watch the classified section...$250-350 is the going price. opening is 75mm or so, which means a stock TB is all you really need. ported helps though.
going just by the picture, that one you linked is NOT the slp version. the slp unit came with the EGR hole in the snout, which worked well for those who need emissions.
