I suspect that several of the failures occurred with the car wound out in third and the the driver grabbed second instead of fourth. It used to happen a lot on the E36 M3s. Guys would tell the dealer that the motor "just quit"; the dealer would interrogate the ECU and discover that the rpm at the time of failure was 9000 or higher.
this is because everything that Subaaru drops the 2.5 boxxer into, including the forrester, will blow. some think was cast incorrectly, and many of these cars that were made in this time frame make it only about 8,000 miles or so from new before this happens to them.
Electronic soft rev limiter protects the engine from overwinding with the accelerator pedal. Soft rev limiter does absolutely nothing to protect the engine when you are intending to upshift at high rpm and grab a lower gear by accident. That's all purely mechanical. That will really do a number on internals, especially the valve train. Drop a valve into a piston and you've got a real problem.
Hey, Old Dude. I'm 59 years old and been racing and modding for four decades now. Great to see you joining in the fun.

And all this time I thought that at 52 I was the old fogey. I built a Q-Ship Monte Carlo street racer back in 1976 and I haven't slowed down since...
come back when you have a heavy modded MS3 with more torque then god knows what to do with in a FWD car. my 1-2 are both over in a matter of about 3 seconds with a mix of pull and hard spin. You will easily bounce off the limiter before you know it.
but will still be slow
lol +1 .. y is that though, that the 6's dont make nearly as much power as the 3's.. their tranny kills them that much?.. i knew a kid who had one with meth and a gt28, he only made like 345whp on an aggressive tune..

its not the transmission, its the two extra wheels that need to be spun

i don't think its people mis-shifting, if that was the case i think there would have been a whole less engines blowing up.
since the blow ups are so random, stock car, slightly modded, and heavily modded it is probably something we don't have much control over without changing parts.
like other said, its probably detonation that are killing us. fuel pumps are not outputting enough. Like one member had the hesitation and stuttering on 4th and up on part and full throttle, it turn out to be his fuel pump. If my dealer wasn't being dumbasses and replaced my fuel pump i might have not blown up. My hesitation and stuttering turned into a bent rod and the bent rod turned into a broken rod and block.

And then there's the extra weight of the MS6, both from all extra drive line and the basic increased weight of the Mazda 6 body. Every 100 pounds eats up 10 horsepower.
Curb weight:
MS3 - 3150
MS6 - 3590
Dyno numbers don't mean jack in predicting acceleration when the cars don't weigh the same thing.

I couldn't agree more! Gearing also makes a big difference.
The 75hp FSAE car I raced was good for a ~3.8s 0-60 because it was 480lbs... just to illustrate the point.

Can't say I agree with you here. The '00 Celica GTS (VERY fast car, just no torque!) I used to have weighed 2500lbs and had 180hp. It also would do 0-60 in 5.3 sec, IIRC. That's ~90 hp down on the MS3 and 650lbs lighter. (Now, I do realize your thought is an estimate, so I'm really not busting your balls about this. Just giving my $0.02.)

5.3 sec 0-60 my ass. Try mid 6's if you're a decent driver. They are on par with a new si which is about 300lbs heavier but an extra 20hp.
Some quick math shows a 5.3s 0-60mph in a 2500lb car would require 206whp over the entire 5.3 seconds... Mid to high 6s would be physically possible...
Also, 100lb/10hp is decent rule of thumb, though always look at the power/weight ratio of the car. An MS3 is about 12lb/hp (120lb/10hp), so adding 10hp or losing 120lbs will accomplish basically the same thing.
The rough estimate of 10 horses per 100 lbs is just that a rough estimate. And it is based on the assumption of cars in the 3000 lb weight category.
But I too have a problem with 5.3 second 0-60 with a 2500 lb car with only 180 hp. Maybe if the car was turning DOT radials, but even then, I don't see that car pulling over 100 mph in the quarter. Sumpin ain't right.
Actually it's a very SLOW car with no torque.

C/D TEST RESULTS:
Zero to 60 mph: 7.5 sec LOL!
Zero to 100 mph: 19.9 sec
Street start, 5–60 mph: 8.0 sec
Standing 1/4-mile: 15.7 sec @ 92 mph LOL!
Top speed (redline limited): 129 mph
7.5secs is a far cry from 5.3sec. A Civic SI would tear that POS up and your argument holds no ground whatsoever. I raced one in a stock MS3 and absolutely slaughtered it every which way imaginable.
