Too many points? I only had one...Mazda dropped the ball.
BZZ, with all due respect since you have helped me many times when I was stuck and needed it... you're not going all corporate on us, are you? I never said I could tell exactly what happened with his motor. It's really hard to tell now that it's in pieces. My whole point is that the burden of proof doesn't lie with the car owner...it lies with Mazda to prove that it wasn't their problem. Assuming, of course, that the car wasn't modified to any extent. That's why the Magnusson-Moss Act was implemented. Right now it looks like it's up to Mazda to prove that the owner was somehow responsible. True, detonation will usually pound on the upper half of the rod bearing and thin it to the point that the backing grabs the crank and spins it, but unless the FS motor is even weaker than I realized, I don't see how this could cause a rod to puke the block and cause the catastrophic damage that occurred with his engine. I know it's comparing apples to oranges, but I spun 7 of 8 rod bearings once in my ancient Pontiac 455 in the T/A once at high speed (7200 rpm in 4th gear...181 mph...I was running from the flashing blue lights...don't ask) and the motor still got me to the house regardless. Sure, it didn't want to turn over again after it cooled back down, but it at least stayed intact. I'm just still at a loss to understand how the hell someone can puke a block on a stock Mazda motor, unless it's a weak ass motor or unless something was way wrong or way weak with the thing from the get-go.
Like I said, Mazda did a lot of things right with this car, but there are a few very important things that they didn't iron out. If it won't hold up, don't build it and market it as a sports car! I'm as big a Mazda fan as you'll ever meet, but I'm not letting them off the hook on this point. If you're going to turbo an already weak motor, at the very least make sure the A/F tuning is right. Same as if you're going to install a LSD from the factory, make sure it won't break under normal "Zoom Zoom" use. If not, be prepared to deal with the consequences.
Right now it looks like this one is on Mazda, and the burden of proof is on them to say that it's not.
