Well we know the sky is NOT the limit for the R154...Albert and Turbo Habanero fried a few stock r154s in their high HP Supras...
should make you questions the W58 number...
Fixed. A properly built R154 will hold quite a bit, remembers it's not the HP that kills things it's the torque. Seeing as the supra engines don't always leave the line under 2-step and sticky tires, there's still quite a bit of driveline shock especially if the rear starts hopping.
I would honestly say if you rebuilt your W58 and never really abused it in 1st or 2nd gear, it would hold 400 ft/lbs for awhile. As soon as you try launching from a sticky surface with tires that'll hook, don't expect it to last very long.
