The Eaton M90 that comes off the the T-bird won't match up to the split port intake and heads of the 99-04's, it will match up to 94-98's though because they are single port. For the split ports you can get an Eaton M112 off of a 03/04 cobra and the adapting intake manifold from Super Six MotorsportsHelpppp. Ive been looking into the T-Bird SC with my dad as he is doing the hard labor while im deployed.... but we have come across and heard that they wont work due to the manifold..... anyone have in depth details on this? i know i can do procharger and yadi yadi ya but this would do me fine. so as i cant be picky any help is appreciated.
