I would buy a Toyota Sequoia long before I swapped a 1UZ into a Runner. A friend of mine has one and it's impressive. We used to haul his big wakeboard boat to the lake passing other traffic without a problem. I was shocked how powerful it was. Of course he was one to push that accelerator pedal all the way to the floor without mercy. That 2UZ is a great engine. It's surprising how low I've seen prices on the older Sequoia's drop on the used market. I put my 1UZ into my truck partly because I love tinkering with things and building engines. If you are just interested in the end result upgrading to a newer or larger vehicle is without a doubt, the best move. I would have bought a Tundra and started building around that if I had to do it all over again. Would have saved some money doing it that way for sure.
