The Borg Warner K03 turbo is the same turbo used in VW vehicles, the Eco just uses 2 of them for more flow. I haven't heard of a single person shying away from a Jetta TDI or GTI because it had a turbo. I don't understand the hesitation with this powertrain. It's grossly overbuilt and engineered for the job its supposed to do.
It's because people rely on hearsay way too much. The Eco had some problems up front; the major reason it became such a big deal is the number of engines that have been sold. I believe it's over 650,000 Ecoboost engines just in the f150 line. The rate of failure/problems is actually very low considering the number of them sold. There will always be problems with a production made product, the higher the number of them made the more you will hear about it.
I do think that Ford mislead people on the maintenance though. Because of fuel dilution with direct injection, oil changes should never exceed 5,000mi and spark plugs need to be changed and properly gapped every 20-30,000mi. The vast majority of problems with the Eco come from worn or improperly gapped spark plugs.
I agree, it's a very robustly made engine that is designed for far more power than it makes in stock form. Just look at the specs for the GT and Raptor. The GT is around the 600hp range and the Raptor is 475-550hp while putting down over 650tq.
