What's your take on Ford throwing Ecoboost engines in everything? Gotta be shortening engine life.
Blown engines have bigger effective displacement.

It goes like this, NA engine operates at 1 bar.
So if your eco boost engine is 2.0 liters and on top of atmospheric pressure you blowing 15 psi into it, your effective displacement is 4 liters.
You have more parts to go bad with turbocharging. But it does not mean it won't last well past 150,000 miles (provided you doing 3,000 mile oil changes). Obviously, something else to standard naturally aspirated engines will break.
Ecoboost engines have chains, but the chains they use tend to break, at least it was one of the illnesses.
I wouldn't go with ford ecoboost engine, since neither Ford nor other domestics know how to make good small engines. For small engines you should go with Toyota and Honda, or Lexus and Acura. However, Ford is known for solid V8 engines. Money you overpay upfront is well worth it in the long run. However, if you don't care to keep your car for too long, Ford Focus manual could be a nice sporty choice.
P.S. - quick word on motor oils. Many think synthetic is the best type and should be used exclusively. It is only partly true. Synthetic is good for high heat, racing, traffic, and other high load conditions. Otherwise, for quick drives it can actually hurt your engine, as it never gets warm enough to work properly. You should be using whatever your manufacturer recommends, but not obeying their 15,000 mile oil change recommendations. Also, once you use one oil, stick to that oil. Don't be that guy that goes with whatever is cheapest at walmart. This causes oil deposits, clogage, and premature wear. Best oil is always your manufacturer's brand.
