VVTi into non-VVTi truck? (1 Viewer)

Currently looking at a cheap 100 with a bad engine.

We have an '05 Tundra parts truck that we'd bought to re-body our farm truck. Farm truck has a good 2UZ in it, I was going to sell the VVTi engine from the parts truck, but I got to thinking...

High miles but I know it's good, we drove it almost 500 miles home (we needed an RCLB, and RCLB parts trucks with decent bodies are hard to find here in the heart of the salt belt) and it ran great, good power.

Is this a swap where anyone's done it before? Or I'd be having to figure it out as I go?

Most of the engine is the same besides the variable intake manifold, the SAIS, and the VVTI. You can block off the SAIS ports easy enough. I think the variable intake works off vacuum so it should work if you keep the system intact. As for the VVTI, it's a pretty simple solenoid switch which you could wire up to an aftermarket RPM switch.

There's a couple threads on it, but don't think anyone's done it. Since you have the whole truck there anything that came up with the ECU or harness you'd at least have available.

That's a very interesting point! But would fueling be close enough to correct if I'm running the VVTI separately from the ECU? IOW, any idea how much extra fuel the ECU sends to the injectors when the VVTI hits?
