That is for a 20valve 4AGE with VVT. 4 independant TB's. Well, According to my Chilton's manual, the 3AC has 75ft/lb of torque at 2800 RPM. It also has 62 horsies at 4800 RPM. According to that dyno chart, The 20v 4AGE VVT makes about 90 NM of torque at its lowest point, about 100 NM of torque at around 2800 RPM. It makes 10 KW at its lowest point, and 80KW at 4800 RPM. That comes to 66.4 ft/lb @ 2250RPM, 73.75 ft/lb @ 2800 RPM. Torque is looking fairly even between the 2, just that the 4AGE keeps climbing to 155NM @ 6000RPM or so (114.31 ft/lb)
The HP figures come to 13.4 hp @ 1 RPM, and 107.24 hp @ 4800 RPM. Climbs to 154 horsies @ 8100RPM.
So its looking like the 20v VVT 4AGE w/ Independant Throttle Bodies beats the tar out of the #AC in the HP department, but is even for torque, till the 3AC's peak, where the 4AGE keeps climbing. Unfortunatly, there are no flat spots in the 4AGE's torque band.. Just 2 peaks. I imagine the 1st peak is where the VVT kicks.

That is a Dr.'s writeup on his 16valve to 20valve conversion in a MR2
