I will be making one this summer. I have a 85 jeep that the 2.8 V-6 has broke the crank and rod went through the side of the block. So my replacement is a 2.5L DUKE that is given to me for free! I am going to fab the header. Run a T-3 draw through style turbo I picked off a 2.3L Ford fairmont in the JY for $50. The only part I have not figured out yet is the oil feed. As the T-3 I have is only oil cooled. It will need a good stream of oil. Not sure if a HV oil pump will be enough but will find out here next winter. As I winter in AZ.
