well, depends on the 18R also. they weren't torque engines(had less stroke, only about 2.0l i think), but it was made in several configurations, most notably the 18R-G that made about 140hp, and often pushed much higher. better swap for a celica though, and kind of hard to find since it was never sold in the US.
the 18R-C that was sold in pickups and celicas here from '73-74 made about 100hp or so, but low on the torque.
