I just found some pricing info...
Drag gen III is about $3,000. From their website, it includes:
Super efficient and powerful Garrett T04/T3 turbocharger; 4 into 1 cast turbo manifold; Turbonetics Deltagate wastegate; Custom 2.5 inch down pipe; Wastegate dump tube; Larger efficient front mount intercooler; Chrome one piece intercooler and turbo piping; High flow performance fuel pump; Vortech boost dependent fuel pressure regulator; HKS Super Sequential blow-off valve; All necessary plumbing; MAP bypass valves; High flow intake filter and piping.
Some of the items in there are rather undesirable; for one, change out that deltagate for a tial.
The Greddy is in the neighborhood of $2,500 but it doesn't come with a front mount intercooler. If you do a search for Drag Gen III's I'm sure you can find more info. from the forced induction techs around here. Hope this helps for now.
