One thing I noticed about the 3RZ is the peak torque number. The specs I've seen show peak torque of about 177 lbs at 4,000 RPM. At freeway cruise speed of between 75 and 80 MPH (3,000 to 3,200), my RPM is right in the middle of my peak torque in my 22RE. With my rebuild specs, my engine should be producing about 154 lbs of torque at 3,000 RPMs.
Of course right now it ain't produc'n didley!!!
How many lbs of torque is the 3RZ producing at 3,000 RPMs?
