The vvt on both the black and silver is the same Mechanism. VVTI has the same features as vvt, but also has the ability to change lift and duration. The only toyota engine that has this is the 2zzge
from club4ag
Its bullshit.
VVTi cannot change lift, only duration.
VVT is ON/OFF
VVTi is variable.
VVTLi is lift aswell (The 2zzge is correct)
EDIT: By bullshit I am not referring to the first sentence, just the 2nd.
