Engines blow up, as soon as people think they are a problem every single case is known. I've heard of just as many blown 1HZ's but they don't have the same reputation... I worked in technical assistance for Holden and heard of every 4JX1 (Jackaroo 3.0 TD) failure, but after speaking to plenty of people with them - they love them!
At the end of the day they are a smaller engine in a big car, it's working hard so won't last along as a larger capacity engine doing the same job.
Get used to it, small, high boosted engines will become far more common in the future.
