If it was me I'd go with the 5.0. JMO
In regards to longevity with turbos. Turbos have been used for decades in Europe with excellent results. I personally don't think durability is going to be a concern. Anything new is always suspect thats just our nature but in reality turbos are only a relatively new item here in the states. With the new and improved oils and engine technology they should run as long as a naturally aspirated engine.
