All of these things will result in accelerated rod bearing failure. When you get oil to the bearings they are fine. Do something to prevent proper lubrication and you have trouble.
I guess it would be stupid to assume Honda drivers are more diligent than SR20 drivers when it comes to proper lubrication. This makes me think Honda's general engine lubrication design is probably a step above what the SR20 has. Maybe their oil pick-up and scavenging is better, maybe their oil pressure operation is more stable under cold temps, etc.
When treated properly, the SR20 is as reliable. Maybe it doesn't take abuse as gracefully as a Honda motor.

Maybe Honduh owners generally don't have the balls to rev as much, and as high, as SR owners.
