My conversion cost a total of $6,000 for everything and I did the labor my self, except the drive line. This included the engine w/flywheel, starter, ect. , intercooler from a 99 ford, 3:55 gears, gauges, adaptor plate and engine kit from FordCummins, drive line shortened 3", exhaust and all the shipping. 24k later, it's still running great. Mine was a gasser, but the cost should be about the same and the powerstroke would be easier to do because you don't have to mess with the fuel tanks. You will need to do a throttle cable. For my tach, I used an Isspro 3 3/8 programmable gauge and isspro's sensor. Hope some of this helps.
