pappy said:I dread the day I find a 3RZ in the local u-pull boneyard. The thought of taking a day to pull the engine. The thought of storing it in the garage until I'm ready to install. I hope I never find the engine because I'd pull it in a heart beat to replace my 22RE. And Marlin sells the bellhousing to mate to my R151F. Oh goody, no Tacos at the u-pull today. Ya, there is no way I'd pass up a 3RZ for my 4Runner.

4WheelUnderground said:Power to weight is the concern. I did the 3rz swap back in 99' and while its a great upgrade and adds 50% more power over the 22re, the 3rz weighs the same as a 1uz that has nearly a 150% - 200% upgrade in power. It costs more but is a huge power gain. The 5VZ is great but weighs more and has less power than the 1uz. I certainly wouldn't go that route if a the 1uz was an option for you. Any one of those motors is an upgrade from the 22re. In the end you may find you go with the one that you can purchase most conveniently.
Who has installed a Tundra V8 in a mini? IIRC those engines are a tight squeeze in an 80 series Land Cruiser. I don't see them fitting easily in a mini.
My 22RE has, and continues to be, a fine engine. Is is a rocket ship? Nope. Does it fit my needs? Yep. Would I like a modern 4-valve-per-cylinder 3RZ? Dang right. I've seen a 5VZ in a Gen1 4Runner and it sure looked like more work than I want to attempt.
No matter how one looks at it the 3RZ is a significant upgrade over the 22RE.
