Yota 1NZ-FE engine has 103 ft. lb. of torque. More than an A15 -- which will sooner or later break the H145. Especially if a steep 1st gear transmission is used. Some have reported the H145 lasting for a while behind an A15, but it is not rated for long-term durability. TS-Cup racers used H145 but had to be very gentle and they still broke sometimes. They also used diff coolers.

Remember, the higher the engine revs to make peak HP, the lower the torque will be. HP and FT-LB figures cross at 5250 RPM. For example, a 100hp@7000 RPM engine vs 100hp@6000 RPM -- the slower engine will have more torque. And torque is what breaks gearboxes and diffs.
