If you install connecting rods from specific year 1uz they are more robust and will allow the 2uz to handle more boost. Forced induction is easier than a engine swap to a different engine. I believe under dog racing has a supercharger kit. Turbo would be best though.
The 5.2L stroker was available years ago but no longer. I read that there were issues with long term wear on the cylinder walls. More info on lextreme.com
Lots of comments in this thread are why I settled on cams. I can leave the block in the truck and don't have to touch the bottom end. I can use slightly thinner head gaskets to increase compression also and redo all my cylinder head seals and timing belt at the same time to get it ready for another 300k. Also with the heads off I can weld the air injection ports up and that allows much better header options (for VVTI).
Oh yeah and I'd be in only $3-4k.

How much are you willing to spend?
I've thought about this and come to the conclusion that if I need more low end grunt, I'll look into a Level10 racing transmission with a billet torque converter and a higher stall speed. I have good experience with Level10 on a different car. The higher stall speed is like having a lower gear ratio for take off. Top end still locks up for fuel economy on the highway. I see it as getting the best of both worlds. Cost would be in the $4,000 range.

Thanks Abuck, was just at Cruiser Outfitters the other day picking up some stuff, they're local to me. I'll definitely give them a shout, should have thought of that myself
Something that I have not seen discussed yet is regearing. The 4.88 gears in my truck make a big difference. Especially with the 34" tires I have on the truck now.
Steps to follow:
-Take pictures of 100 interior and exterior
-place on Craigslist and sell 100
-put new funds towards 200 for the mighty 5.7 with about 400 hp and torque.
Easy peasy.

Ha ha you are totally correct. I am not sure how I overlooked that!

My 2UZ journey started in 2005 with a 2000 2WD Tundra. Over the course of the years I added a COI, JBA headers, Magnaflow cats, JBA Y-pipe, Vibrant resonator, Magnaflow muffler and a Unichip piggyback ECU "tuned" for 92 octane. It was a LOT more drivable, rarely downshifted and was much more comfortable to drive than stock.
Early 2019 I bought a 2005 Sequoia. Sequoia's are about 1,000lbs heavier so I knew that I was going to want the 5 speed trans and additional power that the '05+ came with. Given the weight penalty I was still expecting it to be a dog but I was pleasantly surprised, shocked, really. The thing had no problem getting out of its own way and was still very easy to drive even after putting 32" tires on it.
I get where you're coming from, totally. However you've got the lowest power engine coupled with a 4 speed trans pushing around about 5100lbs dry. If you want more scoot (reliably) then you should really look at an '03+ for the 5 speed trans or an '06-'07 for the additional power as well (or a 200). As much as I'd like to throw a welded stroker in or see someone else do it there are a lot better ways to burn your money. The performance aftermarket for the 2UZ is nearly non existent and the trade off in reliability and durability just isn't worth it, IMO.
If you want to stick with your current rig and add power just be sensible with it. DT headers and a full exhaust will open it up. A variable length intake from a VVTi 2UZ can be swapped on as well. Of course make sure your maintenance is up to date. 4.88's if you've upsized your tires. But I really wouldn't go beyond that.
