I wouldn't say pissing in the wind. I did the 3RZ swap and have to say while its not power monster, it is a good swap for anyone wanting more than a 22RE will put out. The 3RZ motor seems to be more responsive than the 3.0 with the same amount of power and gas mileage the rivals the 22RE. And because it makes its power around 3000 its great for the freeways. However there are no kits for it that I now of. This is were the 4.3 swap starts to look good, as there are plenty of people that have done it and lots or resources to draw from. Not to mention that if you are power hungry you will start with and beable to do more with the 4.3.
