I think the EcoBoost is a great idea as long as it's engineered for a truck. With a direct-injected engine, the compression will be high enough to aid efficiency and low end output and the turbo will take care of the rest.
If Ford can't build an engine that can go 150K without spitting out head gaskets and turbochargers or melting down, then they shouldn't bother. But if they can, I'd buy one. I miss having a truck.
I've also been given an 84 Eagle SX4-Got it running and gave it away, a 1995 Dakota 4wd. (fire damage) an 86 f-150 fixed and gave it away, and recently a clean 1996 f-150 that needs and engine.
