There are quite a few things you need in addition to the actual turbo units. You would most likely need a bigger fuel pump (300 lph Focus would do fine), MAF, Injectors and a tune. If I were to actually purchase a TT setup for the 3.8, I'd be getting it here.
Unfortunately I haven't heard too much as to if Andy is still making turbo setups for the v6's. I know he stopped a while back.
