The Ford Probe had 4 diffrent engines. Of them, 3 where originally Mazda's (the MX-6 and probe are identical). The trashed engine appears to be one of the 2nd Gen v-6's, a KL-03 or KL-ZE. There are two dead giveaways- One are the valves, 4 in each cylinder. The second is the block made out of cast aluminum. Stock, it was advertised at around 200 HP
With out knowing anything else about the engine, it's impossible to say how much power it was producing. My guess is that the boost didn't kill it, but something causing premature ignition or detonation. Bad gas perhaps. This forced a piston down on to the rod before it passed TDC, and the rest of the pistons died as everything became unbalanced and generally messed up.
As it happens, Mazda engines are, for the most part excellent. I have one in my Miata that after 15 years hasn't had a single problem. They were made by the guys who figured out that rotary engine thing after all.

You can buy tuned crate v8's that easily make a reliable 1000 with out anything fancy going on. Not to mention about 4 times the torque.
