Your not talking to the right people then, no this tranny will not last very long at high torque numbers unless you granny shift most of the time...one individual I know (high HP early adopter) has already gone to a Tremec on his DD , he has broke two Aisin's, Robert Stout's racing FRS early on went to a bespoke Hewland . Sure OEM will last for awhile,but don't expect reliability . At this price point don't expect things to be "over built" in fact just the opposite. There is a safe point probably for this engine and drivetrain where your not over taxing the design limits and should expect some decent reliability without a ridiculous amount of supporting mods, IMHO that's about 50 to 75hp over stock. But it won't be in the double the torque and horsepower area,...
