I think saying $15,000 to do it is a LITTLE over estimated. You can get a whole 2003 SRT4 for less than that and swap everything over.
The point is, if you want the 2.4 torque like the SRT4 has instead of turboing the stock 2.0, swap to the 2.4 NA engine and build it up and boost it cheaper and easier. Josiah, do you have pics of your setup or a walkthru that you followed that you could post for him?
