My throttle linkage has so much play in it that when flooring the pedal, there is about another 1/4 inch to the WOT stop (According to the S-AFC, I get ~60% throttle when flooring it.)

I would like to replace the throttle body with an SVT piece. What parts besides the throttle body itself do I need for the conversion? Besides losing the traction and cruise control, what are the other side effects? How does the standard Duratec respond to the larger throttle body (i.e. noticable power gains, quicker response, loss of bottom end)?

Thanks.
