Will 3UZ VVTI cams drop into a 2UZ VVTI? Has it been done? Has anyone measured the lobes to compare? What about 1UZ VVTI I believe they are different and won't work? Thanks. Looking for a low-cost option vs. custom cams just to see what is possible.
 
I tried to use Toyodiy to figure it out but could only get a list of factory parts. I guess it will remain a mystery.
 
For the intakes; 2UZ phaser is too different in the way it functions (there appears to be a middle timing position)...versus the 3UZ/1UZ VVT phaser rest in full retarded position and the oil pressure pushes it to advance. Physically they do fit though (the camshaft is different lengths, but with the phaser, it is the same length. This is VVT, not sure about non-VVT

The exhaust are interchangeable
