I face a similar situation, and have scoured the internet/forums for info. As yet, there are no turbo kits for 2.3 duratec Rangers. There is a site that has everything needed (focussports??) for fusion/focus, but the gear doesn't cross-over to the Ranger. Nice to dream about the potential. There are companies that provide serious work for the LIMA engine, but that doesn't help us.
At 1 time there was a build in process that was to be the forerunner of a turbo kit for the 2,3, but I think the company didn't survive, and have seen no more on that project.
Turborangerforums is an interesting place, and showcases some 1 of a kind rigs. Long story short; there's not anything readily available on the after market to fill our needs, YET??
