When adding HP to a stock vehicle strength of components affected should always be a consideration.
Swapping engines with more power – torque – is going to add “strain” on the drive train. I believe it is a fact that the drive train of at least the early Toyota pickups is considerably stronger than other vehicles in its class. I believe the drive train on my 1986 Xtracab is plenty strong enough to handle a 225 HP Chevy 4.3L Vortec, for example. Or, the 276 HP of Toyota 4.7L V-8.
Can you, at will, break something in the drive train of a 96 HP Toyoto truck? YES.
Driving a vehicle with a significantly increased HP engine or high performance modifications doesn’t mean you have to be an idiot or foolish and abuse it.
The guys that I know who have done engine swaps and the many posts in Toyota forums, I don't recall hearing or reading about having to upgrade drive train components because they experienced unusual failures.
Gnarls.
Keep in mind these same manual in the 2wd versions are found in the supra, which have way higher HP and TQ values over the trucks/SUVs do.
7MGTE had the R154 (similar to the R150Fs)
