and.... that's what happens when you hear that awful metal on metal sound for 5,000 miles....

 
Seen that a few times. We had a few older woman customers bring their cars in with huge chinks missing from the rotor

Holy crap. that's must have been making a ton of noise. How do people do it?

 
That... is a lot of boost. The powerstrokes make 30+ stock but they're sleeved. And gthere's still issues with them

Diesel is a whole other beast. Engine design is different, cyl pressures are far above even what that TA motor saw.

 
Gas powered engines are cast aluminum, very lightweight cuz they are used for the daily driver.

Diesel engines are cast iron, that is why when you see turbocharged applications, boost is between 30 and 40 psi.

Another thing. Gas engines combust by ignition(spark), whereas diesel is by compression. If you look at the compression ratio between a diesel engine and a gasoline engine, you are looking at 21:1 and 10.5:1 roughly.

That is why diesel engines are cast iron. The block needs to be strong to withstand that pressure to support combustion.
