I detest the Toyota diesel, especially for what Diesel Toys wants for it. It's pretty gutless, and I'd rather have the Cummins, if you could legally install one in the 4Runner. Plus parts availability is stupid simple.
Having driven a 4th Gen with the Cummins 4BT, an old Tahoe with the 4BT, and several of the D4-D conversions from Diesel Toys: I would much rather have the D4-D engine. Expensive? Yes. Worth it? IMHO - Yes. Can I afford one? NOPE!
Side note: I have no experience with the new Cummins engines, but it is all irrelevant as it is still cost prohibitive for me.
