Because your automative engineer I had some questions for you:
1. What do you of the turbos? Because I heard that turbos are pretty bad for engine’s.
2. How much miles do you think that engine will last?
3. What do you think about the transmission? Because I heard that it’s pretty bad.

Hi here is my response to your question
A properly designed turbocharged engine will last as long as a N/A engine when cared for properly
The ecoboost engines have steel compression ring lands (like diesels)
They have reverse twist compression rings
They have forged split beam connecting rods
They have deep skirted blocks with six bolt mains (side bolted mains)
They forged crankshafts
These engines are designed like diesels & are very durable
Here are some links

The transmissions are very durable
I reprogram the transmission along with the engines so it will work well with the increased engine output
When driven conservatively (normally) I usually get better fuel with the recalibrated engine VS a stock calibration
I drove our 2011 F150 3.5L ecoboost for 110k miles with no issues
I know a lot of posts on here complain about the cam phasers rattling
They can do so when in very cold conditions
However they are well designed are very durable & the noise goes away in a few seconds
So for me that is a NON-ISSUE
I always use full synthetic oil & never use anything less than 91 octane fuel
Turbocharged engines will produce the same HP & Torque at high altitudes as they do at sea level whereas N/A engines will lose about 3% hp & torque for each 1000ft above sea level
I will always choose a turbocharged engine over a N/A engine for the above reasons & many more
