The 2.9 bent six that Alfa uses is a fine engine.
That "horrible" 3.5 Ford uses won Lemans and beat Ferrari.
This "my favorite engine is better than your favorite engine" BS is the equivalent of "my dad can beat up your dad." Yawn.
How about a mediocre V8 compared to a powerful 6 cylinder motor?
A lot of BMW people would rather have an inline 6 cylinder. Sounds like the new Defender inline 6 cylinder is quite good.
Dust will eat turbine blades in a turbo too. Years ago Ford sent us laminated color charts showing the turbine blades worn off a turbo for a 7.3 Powerstroke from dust from poor filters. No warranty. Use a good filter and change it when needed. Don't be cheap.
Local construction company ran cheap filters that tore along the sealing edge. The bought a couple of turbos.
