Taking things in a different direction, what can be done to maximize torque on a 1UZ engine? It may be that these are not designed for torque but I have an interest in using this engine to drive a propeller for an airboat application. Automotive engine airboaters use reduction units (2:1 to 3:1) to keep propellers below 3000 rpm. The conventional thinking among airboaters tends toward lower rpm, huge cubes and keeping things simple. (carberators) Big torque seems to rule. These fellas undoubtedly know their stuff, I am sure the 600 cube chevys work, but I just want to explore the area outside the box a little.
