i think the one u r talking abt is the one showed at the klims 2003? apparently, there were only one unit ever made, and it was aerotech who did it for ford. ford originally wanted to make 60 i heard but the car wasn't selling so the idea was scrapped.
i called them and they quoted me 30k. it may be reasonable for those who have the $$$. but its all HKS, so i guess there's nothing much on quality issues. the price would include the manifold, turbo....etc. the usual bolt on stuff. as well as a new computer, specially programmed for it. (apparently 5k there). an oil cooler would also be installed.
the idea according to aerotech is to create a car as reliable as the ori. so there u go. $ for quality and peace of mind.
i did a rough calculation, even if u ran haltech/microtech, made a turbo and fabricate all else and had the car running, u would only come to some 10k. HKS VS Home made.
