do you want a quick spool turbo or one with lag. for a quick spool around a .68 trim like a GT28r the higher the trim/AR number the more lag you will get. TurboTom makes a good kit for the Zetec (you would have to supply your own turbo) he does the tune and all. FsWerks makes a complete bolt on kit for about $4k, comes with every thing you need to just bolt up and do some runs to get it dialed in.
Hope that helps some.
