hmmm... i think i understand now... thnx u guys can continue to have a debate over whether or not the rods in a vvti motor are smaller or the same size
someone told me something i have never heard today...

2jzgte and 1jzgte VVTi have the same rods as their non VVTi counterpart.
NA VVTi 2jz and 1jz are thinnerEvilempire1.3JZ-GTE;1524227 said:
I have one, Have rebuilt them, they are the same. same goes for VVTi 2jzgte.Evilempire1.3JZ-GTE;1524227 said:
VTEC doesnt really adjust time it adjust Lift & duration.
So VTEC haves no benifit over having an engine with a more aggressive set of cams other then better gas millage when chocked off by the less agressive profile.
VVTI actually changes the timing of the cam.
The only thing better then VVTI with aggressive cams would be like mentioned before solenoid actuated valves.
It takes a lot of power to move a valve in micro seconds at the right moment.
So much so the size if the solenoid & placement almost makes it nearly impractical.
Why you dont see it today.

so with vvti and an aggressive set of cams is like the most desired build for n/a's? just get bigger rods to support any kind of horsepower then severe cams with vvti?
