2UZ has 245 horsepower 315 ft/lb torque.
However the pre 98 1uzfe is rated at 250 bhp with 260 tq
I want to say that the two engines have similar horsepower ratings but the the 2UZ has 60 more ft/lb of torque.
The 1UZ is cammed to run higher rpms thus the more HP. I believe that in our situation, we need low end power, to climb over obstacles which the 2UZ is great for.
The 1uz has high compression pistons and needs premium or super gas
while the 2uz will run on regular.
1uz has an aluminum block while the 2uz is cast iron. I believe that it weighs 82 lbs more.
