I called the 1-800 number for mitsu once and actually got to talk to an engineer when I was figuring out if the KM148 would handle the torque of the 2.6T. I got some nice lady on the first human pickup, and she listened nicely, and then actually transferred me to engineering, albeit an english speaking Eng. Dept., who listened with interest ("Wish we'd done that") and told me that it would handle over 300ftlbs of torque...

If you can to them, betcha they'd like to chat about your question, too.
