Slowly, but yes.
I looked at a few options, but circled back to the '94 Explorer radiator I had laying around. To fit it up, the stock radiator mounts needed to go, so I drilled out the spot welds.
My new intercooler showed up, this one fits a Focus or Escape Ecobost 2.0T. (I stayed away from the V50 intercooler for now) It's slightly smaller than the RS intercooler, but looks very similar and meets the specs for hose size and frontal area. It still looked like a pretty tight fit, so I did a lot of eye-balling before cutting any sheetmetal.
My intention was to relocate the battery to the drivers' side to accommodate the cable run to the Cummins's starter and put the air box on the passenger's side close to the turbo intake. It didn't take long to realize that the intercooler needed to be shifted off-center and the battery kept in the OE location. The air box will require a different solution.
Even shifted 3" off-center, the intercooler barely clears the battery.
In a weird twist of fate, The off-setting of the intercooler and its width exactly fit between the uprights of the core support.
