I was thinking of doing this with the 3RZ in an '88 3.0 4Runner with a blown engine. I was going to swap it into my '94 pickup but why not just drop the whole drivetrain in the 4Runner? There are alot of 3.0 rigs running around in "old man daily driver" untampered condition and we tend to write the 3.0 trucks off but it might be a good place to look for clean builders.
