2UZ has 245 horsepower 315 ft/lb torque.sweet .. im going to running 40's with a 1uz im afraid its going to be gutless in high.. i have dual cases with 4.7 cases in the back..
but just stock axle gears. do you know the hp and torque specs of a 2uz vs a 1uz non vvti?
1UZ runs fine with mid grade believe it or not, they pull so little timing is probably why. and as far as torque goes it's pretty much 200 ft lbs at 1200 rpm and peaks around 250. By no means gutless or torqueless. and this is coming from a person who has all 3 mentioned engines, pre94 1uz, post 98 1uz and a 2uz. Albeit the extra 60 ft lbs of torque from the 2u is very nice.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.
