Can understand budgets. A diesel conversion can play havoc with one. A few things to keep in you potential to do list. One would be get rid of that tilted, angled exhaust manifold. That unit came on the CPL767 used in Ford E350 vans. Cummins discovered that the tilt caused premature failure to turbo bearings and seals. Other Ford vans wound up with a top center mounted turbo. A second would be a better turbo. That small H1C was OK for the base 105 HP but doesn't have a lot of potential much beyond that. It's just an antiquated design and not much way to improve on it. A turbo from the HX30W series would be light years better. And as I mentioned, any power plans beyond stock will need an intercooler. If you haven't driven diesels before, be patient. They build power a bit slower than gas engines but that incredible torque is like a giant hand pushing you. Guys often take off an leave me in their smoke but I often catch them or pass them when they caught a stop light.
