Does anyone know if you can replace older Toyota cams with the new VVT-i cams instead of replacing the entire engine? This refers specifically to the 2.7L 4-cylinder in Tacomas. Did they change the whole engine configuration or just the cams, plus controllers?

The cams will have different profiles, the head will contain mechanisms for changing the timing of the cams. If you're looking to throw in any old cams to replace a damaged one it *may* work. If you're looking for performance gains you wont get any, tis a totally different setup that requires all the controller hardware and mechanisms, and a different head.
