My only thought behind this swap is a 3UZ can be found under $1000, and if everything was interchangeable, the swap might not cost anything after selling the 4runner engine. But now I'm learning its more complicated than that due to the ECU/transmission compatibility issues
What can I say though? I like significant performance mods for the least amount of money. When you start getting into full engine builds you're into it for many thousands on top of many thousands for a supercharger. I guess if you have deep pockets thats cool but not all of us do.
Sometimes Toyota makes things easy, like converting my 2001 Tacoma Prerunner into a 4wd with no fabrication work needed, literally bolted a 4wd tranmission/t-case on and bolted in a front diff.
None of the sensors are interchangeable and this has already been done in the reverse order by putting a 2uz block into a car with a 3uz heads while retaining the sensor function and vvti function, you are not the first to do it. What needs to happen is some of the parts from some of the engines interchanged while some are not and the rest are custom machined. The truck will never pass smog again and if anything breaks or doesn't work nobody can help you. Not only that, but the owner who did this 10,000 dollar "swap" was not impressed by the measly 40hp gain in hp for all that money.
