I was told the vvti is interference, but the only difference is the camshaft on the intake side :confused:

Pretty sure the VVTi is non-interference.

from the factory, the 2jz is non-interference... with the right pistons/valves/cams, the motor does become interference

The GE VVTi engines are interference motors. In the repair manual when you're setting the timing, it tells you to turn the crank and make sure the pistons and valves don't hit. I would assume the GTE VVTi is the same.

I believe that is due the cam profiles and the fact that it is higher compression. The piston dome is probably taller.
