I have not had to add a drop of oil to the 3RZ since I first filled it after dropping it into the bay. That is a very good feeling. with the 22R I would check it every time I filled up with fuel. Usually had to add about 1/2- 1 full quart every time I checked.. The standard 22R/RE radiator has been working fine for me. IT IS WINTER and has been cold when I have been wheeling, but so far no issues. beating it pretty good in the mud. Very happy with the performance of the motor. All of the worry about having any issues with the swap and t cases have now passed and the hard work is paying off. This swap is well worth it. The cost of the swap will pay for itself in the cost of fuel alone within a year at most. The difference in power really does make all of the difference when trying to get up and over slippery obstacles or any obstacle for that matter. Id make it almost a standard at this point to put a 3RZ in any yota I own from here on out and will never waste another penny on a 22R/RE to try and squeeze the power out of it- IN MY OPINION!!!!> It would take more $$$$ than what you could buy a "complete 3RZ swap" for to make a 22R/RE any where near as potent as the 3RZ... No offense to the 22R/RE. Its a wonderful tride and true, extremely reliable motor and I am not knocking it. Its just not something you wanna throw a bunch of money into to try and make it fast. The term, " Beating a dead horse," comes to mind. that's just my
