Re: Is 5 valve better than 4 valve?	Mon, 30 May 2005 15:37

With N/A motors like this, I think cam profile and valve timing is one of the most important things. (Again, just putting together what I have read). 4AGE 16v cams are about 240 degrees duration? The 4AGE 20v cams are 250 degrees both on intake and exhaust. I think this is enough to make a fair difference. And with the 20v, the intake cam is timed at either 125 or 95 degrees depending on RPM. Exhaust cam is timed at 109 degrees fixed. I think the basic way to get more power out of any 4AGE would be to get cams closer to 300 degrees, with the lobe centers closer to 100 degrees both exhaust and intake. (Less duration with lobe center at about 110 degrees would work better at low rpm). The 2ZZ-GE is a great motor, I love it. (I get to drive them sometimes). But the way its makes power is still basic. Its just a 16v motor, which makes a bit more because its 1800cc and not 1600cc, and it uses bigger cams with more lift. 292 duration and 11.2mm lift on intake! 276 duration and 10mm lift in exhaust! for the big cams. But the 2ZZ-GE has 2 totaly different cam profiles on each cam. If you changed the computer to get the big cams going earlier, the power band would be more like 4000 - 8200rpm. But they have set it up to be very conservative up to 6000rpm from factory for some reason. [Report message to a moderator]
