I have a friend of a friend over in Missoula who recently had something like 50 HP at the wheels with a stock 22RE with a typically built 4Runner, so 102 HP may be pretty good in reality.
I liked the 3RZ, but I did not personally think an additional 40-50 horse was worth the trouble of the swap. Don't get me wrong it was that "just enough more" that you wish your 22re had. Perfect trail rig engine for sure. It's just that the exact same amount of labor could get you a lot more power.
Next time I do a real swap I want to do a 1UZ or maybe a 2UZ in something. Like a mild looking pickup with skinny 33s on it
.
I think, after having a 3RZ, several 22re, 20r, and the 22r that the 22re EFI is the limiting factor, both the best and worst thing about the 22re. I can net large perceivable, seat of the pants changes with carb with a small amount of effort, where you can throw all kinds of stuff on a 22RE and you won't see much after freeing up the exhaust and having a good tune up. I did a cam, intakes, AFM messed with. The header helped, proper gearing was huge, not much else did anything.
I know this rambling is kind of off the topic of the cam thread, but I think the relevance is that what I found over the years was the 22RE is probably happiest in a near stock state of setup.
